2 Introduction
The DA16200 is a highly integrated ultra-low power Wi-Fi system on a chip (SoC) and allows users
to develop a Wi-Fi solution on a single chip. The user implements their application with the DA16200
SDK and the compile environment is the IAR Embedded Workbench IDE of IAR Systems.
2.1 Overview
The DA16200 SDK has eight folders:
● build: Build scripts, temporary build artifacts, or environment files
● customer: IAR project files and applications for customer.
● doc: user documents (user guides, programmer guides, etc.)
● img: to which the images built / pre-compiled are copied
● lib: to which the pre-compiled lib files (.a) are saved
● sample: to demonstrate common use cases of what the DA16200 SDK provides
● src: source codes
● src_tim: source codes for TIM SDK
● version: version files to include when Image created
The DA16200 SDK may be provided with different features per customer or per certain applications
so the source code configuration and the system libraries can differ according to the customer /
application requirements. Dialog Semiconductor pre-compiles the system libraries with the relevant
features enabled before the SDK is packaged. As a result, the customer can modify the pre-compiled
libraries. Features are defined in customer\main\inc\config_xxx_sdk.h (the file name may follow
its reference type) where users can enable / disable some features.
NOTE
Not all features can be freely enabled / disabled. This depends on the pre-compiled libraries included in the
SDK package. Ask Dialog Semiconductor for more details.
The typical IAR project for the DA16200 SDK is shown in Figure 1. There is the possibility to add new
user application files to the existing group Customer_Apps under the cusomter_app project. There is
also the possibility to create your own group, to which you can add files in the “Customer” folder.
Figure 1: IAR Embedded Workbench Project Configuration
Development Environment
The DA16200 SDK only supports the IAR Embedded Workbench to build a project. Users with an
IAR license can download a specific version of IAR Embedded Workbench from the IAR website.

NOTE
Due to compiler compatibility, the DA16200 SDK user should use the exact version of IAR Embedded
Workbench, which is version 7.30.4.
1. Open the URL https://www.iar.com/support/customer-care/my-pages.
2. After successful login, click on Find updates. See Figure 2.
Figure 2: Update IAR Embedded Workbench
3. Click on Other Versions to download an old installer version. See Figure 3.
Figure 3: Install IAR Embedded Workbench
4. Click on 7.30 to go to the download page. See Figure 4.
Figure 4: Checking Version of IAR Embedded Workbench
5. Choose version 7.30.4.XXX.
2.2 Startup Main()
After system reboot, the system library invokes function main(). The following steps are run:
● Initialize HW resources (PIN_MUX, RTC, Console …)
● Start function system_start() to run the DA16200 as Wi-Fi IoT device

}
else
{
PRINTF("\nFailed to initialize the RamLIB or pTIM.\n");
}
return status;
}
After the basic HW resources are initialized, function system_start() is called to run the Wi-Fi
operation. The following happens:
● Configure H/W and S/W features
● Configure system resources for system clock and TX power
● Initialize Wi-Fi function in wlaninit()
● Start of system-provided applications in start_sys_apps()

return TRUE;
}
NOTE
The features supported in the SDK are defined in file config_xxxx_sdk.h (i.e. config_generic_sdk.h) and all
features of config_xxx_sdk.h can be enabled / disabled freely.
If the user wants to change more detail features to handle delicate operations, some features in file
sys_common_feature.h can be changed, but that requires the support from a support engineer of Dialog
Semiconductor.
2.3 Startup System Applications
After running the main function, the DA16200 SDK runs some system provided applications and
user-written applications. Each system application is started by the customer’s define features.

NOTE
The user does not need to modify the system application tables provided in the DA16200 SDK.
If the user does want to modify the system application table, then that is possible but only with the support of
a Dialog Semiconductor Engineer.
2.4 Startup User Applications

2.5 Write User Application
The DA16200 SDK provides an independent customer project named as customer_app. See Figure
8. And in the SDK, the user can add new application code in the folder ~/ customer/apps/src and can
add a newly written application file in the project customer_app such as user_app.c.
Figure 8: Customer Project in IAR Workbench
If the user needs to change to a new SDK, copy the contents of the ~/ customer/apps/src folder to a
new SDK and ~/build/customer_apps.ewp which is the build compile configuration file for the
customer_app project.

The DA16200 SDK provides an interface to add a user application. The interface is designed to
create a user thread. For this purpose, define your application with this interface and then a user
thread is automatically created and run when the DA16200 starts.
The structure of the application thread information is as shown in the example code below:
[ ~/src/sys_apps/inc/application.h ]
typedef struct _app_thread_info {
/// Thread Name
char *name;
/// Funtion Entry_point
VOID (*entry_func)(ULONG);
/// Thread Stack Size
USHORT stksize;
/// Thread Priority
USHORT priority;
/// Flag to check network initializing
UCHAR net_chk_flag;
/// Usage flag for DPM running
UCHAR dpm_flag;
/// Port number for network communitation
USHORT port_no;
/// Running mode of the DA16200
int run_sys_mode;
} app_thread_info_t;
● name [ThreadX feature] Unique thread name
This name is also used to register to DPM sub-system
● entry_function [ThreadX feature] Thread entry point
● stksize [ThreadX feature] Stack size of thread
● priority [ThreadX feature] Thread running priority
● net_chk_flag [DA16200 feature] Indicate if the software must wait until the network
interface is up and running before the user thread runs. If set to 1, the user thread waits until the
network interface is up and running. You must set the value to 1 if your program is a network
application
● dpm_flag [DA16200 feature] Indicate if the user thread uses the DPM function
● port_no [DA16200 feature] Data transfer port number for DPM mode. When a user
thread has UDP/TCP operation with a specific port number, this port number should be
registered to distinguish the data in DPM mode. This port number should be unique in the user
thread table.
● run_sys_mode [DA16200 feature] Runs a Wi-Fi mode (STA / Soft-AP). The application runs
only the specified Wi-Fi mode

2.6 SDK Compilation
After an application is written, right-click on the project name in the IAR Embedded Workbench
workspace and run command Make or Rebuild All. If you compile for the first time, then the advice is
to run command Clean first. See Figure 11.
Figure 11: Compile SDK on IAR Workbench
Figure 12: Build Success on IAR Embedded Workbench
If the build is successful, then there are three binary images created in folder “~/SDK/img”. The
names of the image files are:
● RTOS : DA16200_RTOS_GEN01-01-XXXXX-000000.img
● System Library : DA16200_SLIB_GEN01-01-YYYYY-000000.img

2.8 Make fcCSP Low-Power SLIB Image
The DA16200 SDK provides a QFN-type Ram Library SFLASH image file. After a compilation is
made with the DA16200 SDK, the QFN-type SLIB image with filename DA16200_SLIB-GEN01-01-
XXXXX-000000.img is created in folder ~/SDK/img/.
To create a RAM Library image for the fcCSP Low-Power chipset with the DA16200 SDK, change
the files mentioned below, and then do the SDK Compilation instructions given in Section 2.6.
● binary file : ~/SDK/build/SBOOT/image/DA16xxx_slib_ramlib.bin.fcCSP_LP
➔ ~/SDK/build/SBOOT/image/DA16xxx_slib_ramlib.bin
: ~/SDK/build/SBOOT/image/DA16xxx_slib_ramlib.rtm.fcCSP_LP
➔ ~/SDK/build/SBOOT/image/DA16xxx_slib_ramlib.rtm
NOTE
To make fcCSP image in the DA16200 Generic SDK, Customer/Developer have to remove the RamLib
binary files if exist in ~/SDK/build/asic/Release/Exe folder.
~/SDK/build/asic/Release/Exe/DA16xxx_slib_ramlib.bin

● Compile feature : ~/SDK/customer/main/inc/sys_common_features.h
#undef __FOR_FCCSP_SDK__ ➔ #define __FOR_FCCSP_SDK__
After the compilation is finished, load the SLIB image and RTOS image into the SFLASH and boot
the system. To distinguish it from the QFN type, it shows SDK Version information as "V2.3.X.0 CSP
LP" as below when booting. See Figure 13.

4.1 SPI Slave
4.1.1 Introduction
The SPI slave interface gives support to control the DA16200 from an external host. The range of the
SPI clock speed is the same as that of the internal bus clock speed. The SPI slave supports both
burst mode and non-burst mode. In the burst mode, SPI_CSB remains active from the start to the
end of communication. In the non-burst mode, SPI_CLK remains active at every 8-bit.
The communication protocols of the SPI slave interface use either 4-byte or 8-byte control signals.
Between the two available communication protocols, the CPU chooses one before initiating the
control.

4.2 SDIO Master
4.2.1 SDIO Introduction
Secure Digital Input Output (SDIO) is a full / high speed card suitable for memory card and I/O card
applications with low power consumption. The full / high speed card supports SPI, 1-bit SD and 4-bit
SD transfer modes at the full clock range of 0~50 MHz. To be compatible with the serviceable SDIO
clock, the internal BUS clock should be set to a minimum of 50 MHz. The CIS and CSA area are
inside the internal memory and the SDIO registers (CCCR and FBR) are programmed by the SD
host.
For more details, see the DA16200 Datasheet [1].

4.3 SDIO Slave
4.3.1 Introduction
The GPIO4 and GPIO5 pins are set to SDIO CMD and CLK by default. If SDIO initialization is done
and SDIO communication is enabled, then the SDIO data pin setting is done automatically. In other
words, when the SDIO communication is detected, the pin used as the SDIO data among the GPIO
pins is automatically activated in the SDIO use mode. However, the auto setting function is not
supported for the F_xx pin used as the flash function.

4.5 SD/eMMC
4.5.1 Introduction
The SD/eMMC host IP has a function for the DA16200 to access SD or eMMC cards. The maximum
data rate is less than 100 Mbps. So, this SD/eMMC host IP only supports a 4-bit data bus and the
maximum clock speed is 50 MHz. The maximum data rate is 25 MB/s (200 Mbps) under 4-bit data
bus and 50 MHz clock speed. The SD/eMMC pin mux condition is defined in Table 11.
