Hello everyone,I've been struggling with the ADC of a STM32G474QE on a custom board for some while now. I initially saw a discrepancy between an onboard NTC thermocouple and its measured ADC value. The measured Value (calculated to mV) was off by an ...
Hi, I am using STM32F446RE Nucleo and a Peak CAN Usb to test the CAN functionality of the microcontroller. I have connected the Microcontroller to a CAN Transceiver (TJA1050) and added a 120ohm resistor between the CANH and CANL line. I have attached...
Hello, we are facing some problem entering DFU mode from application code on our custom boards equipped with STM32H7B3 with bootloader release 0x92. On contrary, everything works fine with same board equipped with STM32H7B3 bootloader release 0x91. ...
HelloI am new to the STM32U5 and have problems with I2C communication via GPDMA.My transmit buffer consists out of ten messages that should be send.Strangely, only two write commands are written to the bus. However, this includes the first and the th...
I am confused about the limits of the FT pins on this MCU. I think I understand the maximum voltage on an FT pin except FT_c is Vdd + 4V as long as no pulls are enabled. So with 3.3V Vdd the max voltage on most FT pins will be 8.3V is that correct? I...
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...
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...
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...
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, ...
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...
