1. Description

PoKeys products line consists of simple, easy-to-use USB and network devices with the extended list of features making them powerful input/output devices. PoKeys55, PoKeys56U and PoKeys57U devices also incorporate a virtual USB keyboard and joystick with a simple setup. PoKeys devices enable user to design specially built robust computer interfaces. The devices are highly adjustable and as such require no complex knowledge on device programming. Virtual USB keyboard supports emulation of single key presses or various programmable series of keys (keyboard macro sequences) while virtual USB joystick emulation supports mapping of analog inputs to joystick axes and mapping of digital inputs to joystick buttons. All peripherals can be tested via included software with highly intuitive graphical user interface. Chosen settings can be stored on device, so no special software is needed on target system.
If additional input and output capabilities are needed, the devices provide 55 digital 5V tolerant inputs or outputs, 5 10-bit analog inputs (on PoKeys55) / 7 12-bit analog inputs (on PoKeys56 and PoKeys57 series devices) with adjustable software low-pass filter and one 10-bit analog output (on PoKeys55). These are complemented with 6 high-speed fully configurable PWM (pulse width modulation) outputs. User can freely set PWM period and PWM duty cycles. PWM module runs at 12 MHz (on PoKeys55) / 25 MHz (on PoKeys56 and PoKeys57 series devices) and allows high-speed output switching.
PoKeys devices also support up to 25 pairs of quadrature encoder signal inputs for which can be freely connected to any of the 55 inputs on PoKeys devices. These inputs increment or decrement the counters that can be read via provided software of other third-party applications. Changes in those signals can trigger virtual keyboard presses on USB versions of PoKeys devices. PoKeys devices also support three additional fast encoders, when higher frequencies of the quadrature encoder signals are in use. PoKeys56 and PoKeys57 series devices add additional support for one ultra-fast quadrature encoder signal that can handle even greater frequencies of these signals with ease.
In the cases when the application requires more than 55 inputs or outputs, PoKeys devices have the inbuilt support for matrix keyboards sized up to 16x8 with freely assignable key codes for virtual USB keyboard, while the PoExtBus bus feature adds the support for additional 80 digital outputs.
PoKeys devices also support hd44780-compatible character LCD displays and two serially driven 8x8 matrix LED displays.
Third-party application developers that are adding the support for PoKeys devices, are encouraged to use the supplied communication DLL that can be simply used in the different .NET framework based applications and various other programming languages that provide support for ActiveX interface. There is even an open-source cross-platform C library available at https://bitbucket.org/mbosnak/pokeyslib.
To aid developers that are communicating with PoKeys devices on the low-level, the extensive documentation on device communication protocol can be downloaded free of charge from the product webpage.

6.6. Power supply for PoKeys57E v1.2

PoKeys57E requires external 5-12 V power supply to be connected to the board. PoKeys57E uses switching power supply to power the 5 V power supply bus (also available on pin +5V for external peripherals that require +5V). If any additional peripheral is connected to PoKeys57E board, combined current of peripheral and PoKeys57E board must be taken into consideration when selecting the power supply.
Take care when selecting proper power supply for PoKeys57E. The power supply may never exceed the voltage of +15 V or the PoKeys57E can get damaged.

6.7. Power supply for PoKeys56E (and PoKeys57E v1.1)

PoKeys56E requires external 5V power supply to be connected to the board. If any additional peripheral is connected to PoKeys56E board, combined current of peripheral and PoKeys56E board must be taken into consideration when selecting the power supply.
Due to the protection diode in the circuit, a 0.8 V voltage drop can be observed between input voltage and 5V pin. When supplying the PoKeys56E board with 5V power supply, take care when connecting peripherals that require 5V supply voltage (e.g., LCD displays).

8. PoKeys configuration options

8.1. Digital inputs and outputs

Any of the 55 pins, available on the terminals on the PoKeys PCB, can be configured as digital input or output with selectable polarity. All pins have a weak pull-up resistor enabled and are 5V tollerant.
At every startup, all digital input or output configured pins are preset as digital input pins (with the weak pull-up resistor pulling the state of the pin to logical 1). To enable output function on a selected pin, SetPinFunction command must be executed. This behaviour can be disabled using the SetAutoSetOutputs command or via PoKeys configuration software (Settings > Initialize outputs on startup). Each output pin can sink or source up to 4 mA of current, with the limitation that the pins combined source or sink current does not exceed 100 mA.
All digital input pins on PoKeys55 or PoKeys56U can be configured to simulate a configurable USB keyboard key. When there is a high state on pin (on low state when using inverted polarity option) PoKeys device sends a USB message with the key code and modifier associated with this pin. Moreover, PoKeys device can simulate a series of key presses, what is called a macro sequence. Up to 64 different macro sequences can be setup with the combined total length of 3584 characters with each macro sequence shorter than 128 keys. All macros can be labelled with a 7-character name. Character codes (most frequently used are listed in the Appendix to this document) are USB HID standard keyboard codes.
An extension to the USB keyboard mapping described above, PoKeys supports also triggered mapping of inputs to USB keyboard keys. In triggered mapping mode, only pin state transitions (low­to-high or high-to-low trigger a USB key press) with different key combinations for each transition.
Type-matic like repeat and delay is an additional extension to the triggered key mapping. Instead of relying on the user’s system to trigger key repeat events, PoKeys can be configured to simulate repeated key presses at the predefined rate (period between two key presses is adjustable in 5 ms cycles – 0.78 to 200 repeats possible1) after a predefined delay (adjustable in steps of 5 ms – 0 to 1275 ms possible).

PoKeys configuration software usage

There is graphical representation for configuration of each PoKeys device’s pin on left and right side of main window. To change pin function, click on pin name and change its function in central ‘Pin settings’ frame.
The maximum repeat rate depends on the user's system
25
www.poscope.com
Figure 1: PoKeys configuration window
There are 6 main pin functions possible: inactive, digital input, triggered digital input, digital output, analog input and analog output.
Inactive
Any pin (except those fixly mapped to an activated peripheral) can be set as inactive. Inactive pin is put in high-Z state with internal pull-up resistors enabled.
Digital input
Any one of the 55 pins can be configured as digital input by selecting ‘Digital input’ option box. If the
pin polarity is wished to be inverted, check the 'Invert pin' box.
There are several additional possibilities for digital input pin functions.
Direct key mapping – only for USB devices
Digital input set up for direct key mapping acts like a keyboard key. When there is a high state on pin (on low state when using inverted option), PoKeys55/PoKeys56U sends a key associated with this pin. Select a keyboard key from drop-down box and check appropriate key modifiers (Shift, Ctrl, …).
Example: Send Alt-F4
Select F4 from drop-down box and check Alt checkbox.
Example: Send ( (opening bracket)
This key kombination differs from your system regional settings. As the PoKeys55/PoKeys56U devices emulate a system keyboard, key associations depend on current sytem keyboard regional setting. To send an opening bracket symbol, one possible solution is to press Shift-8 (in most non-English countries) or to press Shift-9. Out of this reason there are no such secondary keys listed in drop­down box and must be entered by user as described above.

Example: starting a program on Windows using PoKeys55/PoKeys56U device
On a Windows operating system, users can assign a custom shortcut key to any program shortcut. Find the shortcut and then right click on it to show the context menu (Step 1). Select Properties (Step
2), and under the Shortcut tab (Step 3), click on the ‘Shortcut key’ text box. Proceed by typing in a
combination that you wish to assign to a particular program (Step 4). Next, open the PoKeys application and connect to the desired PoKeys device. Click on the pin that will function as a launch trigger for your application (Step 5). Under Key mapping, select the same keyboard combination that you assigned to the program shortcut (Step 6). Click on the ‘Send to device’ button (Step 7) to transfer settings to the device. This will activate the new shortcut.

Keyboard macro – only for USB devices
PoKeys55 and PoKeys56U devices support keyboard macros – the key press combinations that can be up to 256 keys long. To define a keyboard macro, first select Keyboard macro mapping option for one
of the pins. ‘Edit macros’ and ‘Get names’ command buttons become enabled. To add, change or delete macros click the ‘Edit macros’ button. The following dialog appears
28
www.poscope.com
Figure 3: Macro editing dialog
First select the macro you want to edit. To change macro name, enter desired macro name (up to 7 characters long) in 'Macro name' text box and click 'Change' button. This name is used only to help user differentiate between multiple macros.
To set macro contents, simply enter text into 'Macro contents' text box. If there is an invalid character found, the text appears red. When finished, click Write to write macro to device.
List box at the right displays final macro sequence that is sent to PC when the macro gets activated.
Triggered digital input – only for USB devices
Any one of the 55 pins can be configured as triggered digital input by selecting ‘Triggered input’
option box. This pin mode enables user to select a key that is pressed only when a transition in a signal occurs. Different keys can be selected for ‘LOW-to-HIGH’ or ‘Key up’ event and for ‘HIGH-to­LOW’ or ‘Key down’ event. Selecting the keys is similar to Direct key mapping described above.
Digital output
Any one of the 55 pins can be configured as digital output by selecting ‘Digital output’ option box. If the polarity of the pin is wished to be inverted, check the 'Invert pin' box. On startup, all pins (although optionally configured as digital output) are by default initialized in high-Z state (behaving like inputs). To use the outputs, SetPinData should be called before attempting to set the output state. However, there is an option to disable this behaviour - use the ‘Settings > Initialize outputs on startup’ option to either enable or disable output activation on PoKeys startup.

Figure 4: Input and output status dialog
There are 55 pins represented as colored squares in the dialog, organized in the rows of 8 pins. Each square contains a pin index number in the lower left corner, while the lower right corner is used to indicate a digital output (small black triangle is displayed on pins, configured as digital outputs). The color of the square resembles the current state of the pin – green for the activated (HIGH state) and white for the unactivated (LOW state).
To change the digital output state, first enable ‘Enable output control’ option, then either left or right click with mouse on the square representing the digital output to activate or deactivate this output.
