STemWin and mbed os

[Bkim.6]

i use disco-f429zi.

Is it possible to stemwin from mbed os?

I tried to use the STemwin library STemWin_CM4_wc16.a file provided by the cube fw_f4 firmware pack, but the code process stopped at GUI_Init().

The development environment is keil uvision5. Is it possible to use STemWin library files in mbed os?

Hello @Bkim.6​ 

Have you enabled CRC?

The CRC must be enabled before calling GUI_Init, if not STemWin will be not function.

This is mentioned in the page 6 of AN4323 to call GUI_Init function prior to use any STemWin function or GUI routines:

"The CRC module (in RCC peripheral clock enable register) should be enabled before using the library."

yes, i enable CRC

in my main.c

main() {
 uint16_t x, y;
 uint8_t text[30];
 uint8_t status;
 TIM_HandleTypeDef TimHandle;
 uint32_t uwPrescalerValue = 0;
 HAL_Init();
 BSP_SDRAM_Init();
 __HAL_RCC_CRC_CLK_ENABLE();
 SystemClock_Config();
 
....
 
GUI_Init()
