In my code, after setting an on-board LED, the timer is started like this. __HAL_TIM_SET_COUNTER(&htim3, 0); while(HAL_TIM_Base_Start_IT(&htim3) != HAL_BUSY);In debugging mode, I saw that the CNT register was in fact incrementing, however in would al...
I have configured the ADC to use pins 1,2,3,4 for DMA transfer. I do get COM port output, however, I noticed that the outputted numbers aren't as they are supposed to be. The values for only 2 of the 4 pins change as they should. The other 2 do not.T...
Hi, I'm working on root cause a Hard Fault issue on STM32H563. The application is a regular ping and response. The system has TrustZone enabled. When the hard fault happens, according to pushed stack info from psp_ns, the call happens inside a mem...
Hi I am trying to commuicate between two boards through UART.One board is nucleof4 and other board is a processor.Im sending a data from nucleo to other board(where data gets displayed) through HAL_UART_Transmit(&huart1,(uint8_t*)"Connect",sizeof("Co...
I have 2 boards, basically identical except one has PHY KSZ8091RNA and the other has KSZ8091RND.Both use the STM32F429NIH6.The only difference I can find in the two PHYs is that I need to set to set the REFCLOCK bit in KSZ8091RNA's PHYC2 register. W...
Hey. I would like some clarification regarding writing to Flash memory. Specificially, 4 bytes (float values).I have the following code: void FLASH_write_single_float(uint32_t address, float data_to_send) { if (address < 0x080E0000 || address > ...
