HAL_SPI_Receive_DMA() won't start a transfer in a CubeMX project that I cloned. No activity on SPI bus. HAL call returns success. .IOC and generated files all compare successfully. (only changed some GPIO, SPI is configured same) What could I be missing ?
I simply wanted to make an identical program but with a different GPIO pinout. The SPI busses are all on the same pins and configured the same. What could I have touched that would cause the SPI transfer to not start ? I had to switch to HAL_SPI_Re...
UART2 Output Stripped - NUCLEO-F401RE
Working on a prototype and am using HAL_UART_Transmit to output to UART2. Upon output over UART2 the string seems to be truncated. Code below:```char stuff[] = "HELLO YOU FINE FELLOW";HAL_UART_Transmit(&huart2,stuff,sizeof(stuff),1);```Output is HELL...
CubeL4, HAL_RCC_OscConfig leaves HSE_ON set even if HSERDY is not set within timeout delay
Dear all,I just found out that the CubeL4 function HAL_RCC_OscConfig() does not reset the HSEON bit (in the RCC, CR-register) in case that the HSE does not start and the function creates a timeout.I am just facing an issue where the HSE-crystal does ...
MAX3232 Stops Translating When STM32L0 Running
I'm trying to interface a L0538 Discovery board to a simple TTL-to-RS232 converter board that uses a MAX3232 IC (off-the-shelf from Amazon). I have VCC, GND and TX/RX from the Discovery board (UART1) wired to the converter board. I used Cube to set u...
STM32H7 triggering a SPI TX transmission via DMA with a synch event on EXTI0
Hi All, Looking at the STM32H7 Ref manual it seems the DMAMUX would allow for a DMA channel to be synchronized with an external event on the EXTI0 input.I would like to use this capability to trigger an SPI transmission to an ADC (since this would al...
[BLE] Immediate disconnection when using HSE clock for RF wake up
I have this issue:I have set the RF wake up clock selection to HSE /1024 and I cannot get a BLE connection to hold.Why is that? Any other configuration might be affecting that? PeriphClkInitStruct.RFWakeUpClockSelection = RCC_RFWKPCLKSOURCE_HSE_DIV10...
Resolved! Counting pulse + direction encoder
Hello,I'm trying to read the pulse counter with a timer on STM32H747. The counter produces pulses up to 100KHz on one timer channel and high \ low signal to define the direction.I tried two approaches.Reference manual says, as I understand, that such...
SPI unaccountable lock. Amazing behaviour. Test software included, STM32F401 Blackpill, no additional hardware required.
My SPI gets stuck (waiting for RX register not empy flag, <SPI1->SR & 1> that never arrives). The operation is written with registers, not HAL.BUT! it only gets stuck after a fixed number of successful repeated operations, all the same, inside a loo...
stm32 interrupt timer1
I want to make 3 pwm with the timer1 on an stm32f103c8t6 and when the timer reaches its reset value an interrupt should be generated. I tried a lot but nothing worked. Can someone please tell me how I do this?
