STM32H755 SPI Slave DMA Issue
Hello, I have been stuck on this issues where I cannot get my SPI slave running on the STM32H755 to successfully do full duplex communication. Right now I want the simplest case to work where the SPI master, also an STM32H755, sends a 16 bit data pay...
STM32N6 H264 Video Encoder ASIC datasheet / manual
Hello folks,I am investigating the Video Encoder on the STM32N6 and have been working through the reference project (VENC_SDCard_ThreadX).The user manual (RM0486) is very vague on detailing the Video Encoder, and lists over 100 pages of registers whi...
TIM13 and TIM14 PWM output issues STM32H562
Hi All,I have a project that is using the STM32H562. I am having an issue using tim13 and tim14 to generate PWM outputs going to LEDs. The project uses timers tim2, tim3, tim4, tim13, and tim14 for a range of different PWM peripherals. For all of the...
Resolved! STM32 Bootloader: FAA DO-178 Certification?
Is the internal bootloader on the STM32H723 DO-178 certified? It just dawned on me that the whole line of CPUs might be disqualified for aircraft use because the bootloader code "flies" with the aircraft and all such code must be certified to the l...
STM32H723ZGT6 USB_OTG_HS in FS Mode Not Detected by PC (No External Oscillator)
(Please see attached PDF for best formatting and screenshot images. Complete code of main.c and usbd_cdc_if.c are also attached as txt.)Hi everyone, This is my first post! Please excuse any mistakes I might make in my question :).Question & Problem D...
Resolved! STM32G431 I2C with HAL gets stuck in the interrupt
I am trying to use a G431 as an I2C device (slave). Unfortunately it can be made to latch up rather easily, getting stuck with an endlessly triggering I2C interrupt. It appears to be a flaw in the HAL code where it doesn't clear the interrupt flags, ...
The program enters HardFault _ Handler, but no valid stack information can be found
Hello, my program runs to the HardFault _ Handler function, I usually use interrupt check whether there is a function variable overflow, but this time the jump function is irregular, I do not know how to judge, please help me, I will provide the rele...
How to count impulses with debouncing at moderate speeds like 400 kHz
Hallo all:I want to implement a generic counter to count the number of impulses on an input, but after debouncing.I guess that mechanical switches for human interface purposes need a debouncing in the milliseconds range, say 1 ms to 20 ms. My Systick...
STM32H7 won't calibrate using STMCubeMX v6.13.0
CubeMX-generated code gets stuck on HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED) using IDE v1.17.0 and FreeRTOS. RTOS is using SystemCoreClock. HAL Tick is using TIM17 with a priority = 14 (Higher than SysTick Timer.)Made AdcTask highest pri...
