Hi, I did found that the Interrupt Handler for LTDC was not beeing called.I to change the following code:extern "C" void HAL_LTDC_LineEvenCallback(LTDC_HandleTypeDef *hltdc) { if (LTDC->LIPCR == lcd_int_active_line) { //entering activ...

Update 2Debugging the code, I found that the generated HAL_LTDC_LineEvenCallback was never called by LTDC Interrupt.extern "C" void HAL_LTDC_LineEvenCallback(LTDC_HandleTypeDef *hltdc) { if (LTDC->LIPCR == lcd_int_active_line) { //ent...
