CIRCUIT DESCRIPTION

1 Power supply

Components: 7201
The power supply makes use of the LT1761 low drop linear regulator of Linear Technologies. The output voltage is 3.3V.

2 Reset & delayed reset.

Components: -reset: 7202

-delayed reset: around 7203, 7204
The S-809 (Panasonic) detects the hardware reset level of the batteries. Below this level (2.8V) reset is passed to the
“delayed reset” circuit.
The “delayed reset circuit” is activated by the S-809 or the reset switch 1203. It will delay the reset signal by approx. 80ms and
has a hysteresis of 200mV

3 Battery level measurement

Components: around 7206, 7207
The battery voltage is measured via a 1:2 divider by the master microcontroller. This divider is switched on/off by the master
by means of 7206 and 7207.

4 EL-foil driver

Components: around 7205
The EL-sheet is driven by the D371 (Durel). This component generates a high-voltage semi sinewave by switching a coil of

2.2mH. It contains 2 oscillators: a high-frequency oscillator switching into the inductor at approx. 17kHz. A low-frequency
oscilator drives the EL-sheet at approx. 500Hz. The EL-sheet is driven with approx. 75Vpeak.
Zener diodes 6208 and 6209 limit the sinewave voltage when no sheet is attached (during repair of the unit).

5 +/- 17V generator

Components: around 7210
The + and - 17V are generated by the MC64063A, a DC-to-DC converter who is used in a step-up configuration.
The switching frequency ranges up to 150kHz (depending on the load) with ringing on the edges of approx. 3MHz.
The generator is switched on/off via 7208 and 7209 from the master microcontroller.

6 Master microcontroller & memories

Components: 7101, 7115, 7103, 7102
The master is the main microcontroller in the system (M30800, Mitsubishi). It uses external flash program memory
(AM29LV800BT, AMD) and SRAM (CY62256V, Cypress). Address selection is performed with 74LV139.
The master runs from two crystals: 7.3728MHz, onlu runing when active. The other crystal of 32.768kHz is always running,
even in sleep mode.

7 Buzzer

Components: around 1103
The sound function is made by a piezo-electric buzzer. The steering frequency range is 200Hz ~ 8kHz.

8 RS232 transmitter

Components: around 7105, 7106
This circuit converts the RS232 outgoing signal from the master between 0 and 3.3V to -15 and +15V levels.
RS232 communication is set at 115kBaud both directions.

9 RS232 receiver & detection.

Components: around 7107, 7108, 7109
Transistor 7107 converts the incoming RS232 signals between -/+15V into 0-3V levels towards the master.
Transistors 7108 and 7109 perform a RS232 incoming signal detection and interrupt the master during sleep mode when
communication starts from a connected PC.

10 Touchscreen.

Components: around 7111, 7112, 7113, 7114
A resistive touchscreen is used, composed of two layers of resistive material. Pressing the screen causes a short-circuit
between the two layers.
The touchscreen is operated in two steps:

1. detection of a touch

2. reading of the actual position of the touch
Detection is done by connecting one layer to ground and the second layer to 3.3V with a pull-up resistor. The voltage on the
second layer will change from 3.3V to 0V when touching.

Readout is performed in 2 phases, each determining one coordinate.
First, layer 1 is connected between 3V3 and ground. The potentiometric position of the touch location can be read by
measuring the voltage on the layer 2.
The other coordinate is read by interchanging the layers in previous procedure.

CIRCUIT DESCRIPTION

11 LCD

Components: 1101
The LCD module (Wintek) is a STN type 100x160 pixel including the driver HD66421 of Hitachi. The touchscreen is glued on
top the the LCD module.
The LCD module uses a 8 bit bus directly iterfacing to the databus of the master.
It uses two voltages: 3.3V for the logic and 17V for the LCD glass drive.
The LCD driver uses a clock of approx. 190kHz to generate all timing.

12 Keyboard

Components: 0102, etc...
The keyboard is a matrix of 6 x 3 keys. It is static when no key is pressed, and scanned when a key is applied.

13 Slave microcontroller

Components: 7301
The slave microcontroller M37540M4 (Mitsubishi) takes most of the real-time functions: IR-sending, IR learning and steering
the database microcontroller.
Sending IR is performed via pins 28 and 29, combining envelope and carrier with AND-gate 7302.
Transistors 7303 and 7304 combine the IR-sending signals from slave uC and database uC towards the IR-transmitter circuit.
The salve uC also switches on/off the power of the learing circuit via 7305.
Bidirectional communication to the master uC goes via a UART at 57kBaud.
Communication to the database uC goes via a 3-line dedicated bus.

14 Infrared transmitter

Components: around 7307, 7308
The IR-transmitter transmits any IR-code coming from slave or database uC.
It steers two IR-transmission diodes with a peak current of approx. 300mA in each of them.
The IR-diodes transmit invisible infrared light at 940 nm in an angle of 2 x 25 degr.
An electrolytic capacitor of 100uF smoothen-out the carrier frequency in order to have only the average current flowing from
the batteries (envelope of the IR-code).
There are many many brands with each several IR-codes. Basically, all codes consist of a low bitrate burst (around 1kbit or
slower) modulated on a carrier of 30 - 60kHz, and repeated at a rate of 5 - 20Hz.

15 Learning circuit

Components: around 7309, 7310
This circuit is used for learning IR-codes. It uses signals captured by the IR-transmission LEDs 6301and 6302. Transistor
7309 amplifies the signal. Opamp LM393-B puts a minimum threshold and amplifies further. The output of LM393-B contains
the carrir frequency and is fed to the slave IC for carrier frequency measurement. The output is also fed onto a detector. This
has a time constant suitable to detect to the envelope signal of the IR-code. Opamp LM393-A cleans up and its output is fed
also into the slave uC for envelope recording.

- Tricks for Remote Controles that are “Difficult”

• Replace the batteries in your original remote control. Poor battery charge in the original remote will still operate original
component from long range, but will corrupt carrier frequency learning

• Change distance. Try increasing distance up to 4 feet. Start in the normal 1” to 4” , then double the distance to 8” and so on.

• Use a short “Tap” instead of a press and hold. A press and hold is only really necessary when you are learning a button that
in actual operation you would sometimes press and hold (e.g. volume up and down, fast forward scan). If your system is large
and you are concerned about memory, try teaching most commands as taps rather then extended press and holds.

• The “Flicker” technique - rapidly tap the button while learning (7x per sercond or faster). This is very useful for difficult
volume up and volume down commands from some manufacturers.

• The “Swoop” - Start from 2’away and swoop the remote towards the learning remote. Use in absolute desperation, out of
sight from anyone who might see you. Reportedly works occasionally.

• The “Flasher” - Hold an opaque object in front of the remote and remove it then quickly replace it. This is especially useful
when you want to capture one part of a macro from another remote.
