1 Introduction
This document provides an overview of the Software Development Kit (SDK) used for application
development based on Wi-Fi solution using the DA16200 (DA16600) devices and boards. This SDK
includes DA16200/DA16600 generic projects, sample projects, a set of libraries, and drivers to
facilitate the creation of various applications by exploiting the provided hardware resources of a
connected DA16200 (DA16600) devices.
1.1 Overview
The DA16200 (DA16600) FreeRTOS SDK has seven folders:
●apps : Project files, source codes for feature configurations
○apps/common/examples: to demonstrate common use cases of what the DA16200
(DA16600) SDK provides
○apps/da16200/get_started/img: to which the images built / pre-compiled are copied
●core : source codes
●docs : user documents (user guides, programmer guides, etc.)
●library : to which the pre-compiled lib files (.a) are saved
●tools : build tools/ scripts, temporary build artifacts, or environment files
●utility : utilities for the FreeRTOS SDK
●version : version files to include when Image created
The DA16200 (DA16600) SDK may be provided with different features per customer or per certain
applications and Customer/Developer can change the features easily in SDK.
All generic features are defined in
~/FreeRTOS_SDK/apps/da16200/get_started/include/user_main/config_generic_sdk.h (the file name
may follow its reference type) where users can enable/disable some features. And detailed features
are defined in
~/FreeRTOS_SDK/apps/da16200/get_started/include/user_main/sys_common_features.h
NOTE
Not all features can be freely enabled or /disabled. This depends on the pre-compiled libraries included in the
SDK package. Ask Renesas Electronics for more details.
The typical Eclipse project for the DA16200 (DA16600) SDK is shown in Figure 1

Figure 1: Eclipse Project Configuration
1.2 Development Environment
The DA16200 (DA16600) FreeRTOS SDK needs the Eclipse IDE . See Section 5.4 and 5.5 of [4] for
Eclipse installation and Getting Started Guide.
1.3 Startup Main()
After system reboot, the system library invokes function main(). The following steps are run:
●Initialize HW resources (PIN_MUX, RTC, Console …)
●Run the system_start() function to start the DA16200 (DA16600) as Wi-Fi IoT device

[ ~/FreeRTOS_SDK/core/main/src/main.c ]
int main(char init_state)
{
...
xTaskCreate(system_launcher,
"system_launcher",
256*3, // for SecureBoot
(void *)NULL,
(tskIDLE_PRIORITY+1),
NULL);
...
vTaskStartScheduler();
}
void system_launcher( void *pvParameters)
{
...
// Initialize and run system application
// and run user application if needed.
start_da16x();
...
}
static void start_da16x(void)
{
...
/* Configure Pin-Mux of DA16200 */
config_pin_mux();
/* Initialize WLAN interface */
wlaninit();
/* Start DA16200 IoT system layer */
user_main(ramlib_ptim_init_status); // USER main
}
The following system initialization is done before applications start:
●Configure H/W and S/W features
●Configure system resources for system clock and TX power
●Initialize Wi-Fi function in wlaninit()
int user_main(char init_state)
{
...
/* Entry point for customer main */
if (init_state == pdTRUE) {
system_start();
} else {
Printf("\nFailed to initialize the RamLib or pTIM !!!\n");
}
return status;

}
After the basic HW resources are initialized, system_start() is called to run system/user
applications. The following happens:
●Start of system-provided applications in start_sys_apps()
●Start of user applications in start_user_apps()
[~/FreeRTOS_SDK/apps/da16200/get_started/src/user_main/system_start.c ]
int system_start(void)
{
/* Config HW wakeup resource */
config_user_wu_hw_resource();
/* Set configuration for H/W button */
config_gpio_button();
/* Set paramters for system running */
set_sys_config();
/* Initialize WLAN interface */
wlaninit();
... ...
/* Start system applications for DA16XXX */
start_sys_apps();
/*
* Entry point of user's applications
* : defined in user_apps_table.c
*/
/* Start system applications for DA16XXX */
start_user_apps();
}
NOTE
The main header files including configurable features are located in
./apps/da16xxx/get_started/include/user_main for generic projects or ./apps/common/examples/*(sample-
groups)/*(samples)/include for sample projects. All features in config_generic_sdk.h are configurable as
required. But some features in the sys_common_feature.h can be changed to handle delicate operations, if
there are anything unclear then contact the Renesas Electronics support team.

1.4 Startup System Applications
After running the main function, the DA16200 (DA16600) SDK runs applications provided by the
system and user defined. Each system application is started by the customer-define features.
Figure 3: Applications on Eclipse Project
[ ~/FreeRTOS_SDK/core/system/src/common/main/sys_apps.c ]
void start_sys_apps(void)
{
...
/* Start user application functions */
run_sys_apps();
}
The system applications run in two parts:
●Applications that should be executed regardless of network settings
●Applications that should be executed after the network setting is complete

static void run_sys_apps(void)
{
... ...
/* Create network independent apps */
create_sys_apps(sysmode, FALSE);
/* Create user's network independent apps */
create_user_apps(sysmode, FALSE);
...
/* wait for network initialization */
while (1) {
if (check_net_init(iface) == pdPASS) {
i = 0;
break;
}
i++;
vTaskDelay(1);
}
...
/* Check IP address resolution status */
while (check_net_ip_status(iface)) {
vTaskDelay(1);
}
/* Create network apps */
create_sys_apps(sysmode, TRUE);
}
All system applications are provided in the sys_apps_table[] as shown in the example code below:
[ ~/FreeRTOS_SDK/core/system/src/common/main/sys_apps.c ]
static const app_task_info_t sys_apps_table[] =
{
/* name, entry_func, stack_size, priority, timeslice, net_chk_flag, dpm_flag, port_no,
run_sys_mode */
/****** For function features ***********************************/
… …
#if defined ( __SUPPORT_MQTT__ )
{ APP_MQTT_SUB, mqtt_auto_start, 320, (U_PRIO), TRUE, TRUE, UNDEF_PORT, RUN_STA_MODE},
#endif// __SUPPORT_MQTT__
… …
/******* End of List ********************************************/
{ NULL, NULL, 0, 0, FALSE, FALSE, UNDEF_PORT, 0 }
};
NOTE
The user does not need to modify the system application tables provided in the DA16200 (DA16600) SDK.

NOTE
If the user wants to modify the system application table, then that is possible but only with the support of a
Renesas Electronics engineer.
1.5 Startup User Applications
After running the main function, the DA16200 (DA16600) SDK can run user-written applications.
The user applications also run in two parts:
●Applications that should be executed regardless of network settings
[ ~/FreeRTOS_SDK/core/system/src/common/main/sys_apps.c]
static void run_sys_apps(void)
{
... ...
/* Start user's network independent applications */
create_user_apps(sysmode, FALSE);
... ...
●Applications that should be executed after the network settings are completed
[ ~/FreeRTOS_SDK/core/system/src/common/main/sys_apps.c ]
void start_user_apps(void)
{
int sysmode;
… …
/* Run user's network dependent apps */
create_user_apps(sysmode, TRUE);
}
All user applications can be written in the user_apps_table[] as shown in the example code below.
The DA16200 (DA16600) SDK provides a “hello_world” application. (Enable
__SUPPORT_HELLO_WORLD__ in
~/FreeRTOS_SDK/apps/da16200/get_started/include/user_main/config_generic_sdk.h to use.)
[ ~/FreeRTOS_SDK/apps/da16200/get_started/src/apps/user_apps.c ]
const app_task_info_t user_apps_table[] = {
/* name, func, stack_size, pri, net_flag, dpm_flag, port_no, sys_mode */
#if defined (__SUPPORT_HELLO_WORLD__)
{ HELLO_WORLD_1, customer_hello_world_1, 64,(U_PRIO),FALSE,FALSE,UNDEF_PORT, ALL_MODE },
{ HELLO_WORLD_2, customer_hello_world_2, 64,(U_PRIO),TRUE, FALSE,UNDEF_PORT, ALL_MODE },
#endif // __SUPPORT_HELLO_WORLD__
{ NULL, NULL, 0, 0, FALSE, FALSE, UNDEF_PORT, 0 }
};

Figure 5: Customer Project in Eclipse IDE
The DA16200 (DA16600) 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 (DA16600) starts.
The structure of the application thread information is as shown in the example code below:
[ ~/FreeRTOS_SDK/apps/da16200/get_started/include/apps/application.h ]
typedef struct _app_task_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 DA16xxx

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 (DA16600) feature] [To Be Used Later When DPM feature is
enabled –TBU_DPM] Indicate if the user thread uses the DPM function
●port_no [DA16200 (DA16600) feature] [TBU_DPM] 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 (DA16600) feature] Runs a Wi-Fi mode (STA / Soft-AP). The
application runs only the specified Wi-Fi mode

Figure 9: Build Success on Eclipse IDE
If the build is successful, two binary images will be created in the~/FreeRTOS_SDK/
apps/da16200/get_started/img folder. The names of the image files are:
●RTOS : DA16200_FRTOS-GEN01-01-XXXXXXXXX-000000.img
●2nd Bootloader : DA16200_FBOOT-GEN01-01-XXXXXXXXX-000000_W25Q32JW.img
(In case of Winbond W25Q32JW SFLASH)
For more information about the firmware download, see Section 4.5 of Ref. [4].
1.8 Make fcCSP RTOS Image
The DA16200 (DA16600) SDK provides a QFN-type RTOS SFLASH image file. After a compilation
with the DA16200 (DA16600) SDK, the QFN-type RTOS image with filename DA16200_FRTOS-
GEN01-01-XXXXX-000000.img is created in folder ~/SDK/apps/da16200/get_started/img/.
To create a RTOS image for the fcCSP type package with the DA16200 (DA16600) SDK, change the
files as shown below, and then follow the SDK Compilation instructions given in Section 1.7.
●Library file for Low-Power:
