Interfacing stm32f1 with GSM
I am trying to interface GSM with my ARM controller [stm32f103c8t6].I knew a little about the working of GSM, - By sending the "AT" command to GSM, it will respond with a "OK" message.Before interfacing GSM with arm, i learned how to use HAL_uart fun...
Is there any disadvantage of turning off the ADC clock between conversions?
Is there any disadvantage of turning off the ADC clock between conversions (to save power)?If I do this for example:RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, ENABLE); ... Do one conversion... RCC_APB2PeriphClockCmd(RCC_APB2Periph_ADC1, DISABLE)...

How to recover from DAC - DMAUDR ?
Hello,I use DAC with DMA on STM32F439 (Nucleo board). Now it happens that I create a DAC trigger although all DMA data is sent, ie NDTR has already reached zero. Therefore DMAUDR gets set. When I want to start a new DAC - DMA run I get an unwanted DM...
Single stepping doesn't run in order
I am single stepping through simple code. I have two similar similar lines in a loop. Single stepping only goes to the last of those lines. This is STM32F746 Discovery and Keil IDE.while(9) { if(HAL_UART_Transmit(&UartHandle, (uint8_t*)"\0", 1, 500...
Resolved! What is wrong with this "HAL_UART_Transmit(&UartHandle, (uint8_t*)'\0'
I am trying to send 0h, that is one byte with 8 zeros. But HAL_UART_Transmit jumps to the error handler.I am using Keil with 746 Discovery.I have tried if(HAL_UART_Transmit(&UartHandle, (uint8_t*)'\0', 1, 5000)!= HAL_OK) { Error_Handler(); ...
