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."

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();
