What is the maximum clock source frequency can I use as an external clock for timer?I have a 20MHz source and PLL frequency made out of this source. The purpose - generate lower frequency pulses that synchronous to that 20MHz clock with controlled de...
HelloIn STM32G474RET6 I want to have 2 banks. Bank 1 for golden (boot image) and Bank 2 for an application image.As I want to have a robust solution I always want to boot from Bank 1 (address: 0x8000000), to check if valid firmware exist in Bank 2 (a...
Hi ,We are seeing STM32F051K6 have a drift of 7 milli seconds per 1 hour running on HSE . Time drift of 7milli seconds for 1 hours is 1.944 Parts Per Million ( 7000 micro seconds / 3,600,000,000 Micro seconds = 0.000,001,944 )The OSCILLATOR has ± 10 ...
Hello,I would like to use DMA with SAI but I am having difficulty writing the code. Can you check if my code is correct and why I cannot retrieve the RX values ? /* USER CODE BEGIN 2 */ HAL_SAI_RegisterCallback(&hsai_BlockA1, HAL_SAI_RX_HALFCOMP...
Ok, 2 part question. The UART bootloader defined the "special" and "extended special" commands. Those are nicely integrated into OpenBL. So if I wanted to write my own custom "OpCode", what range would I use ? Looks like some are used for STM32WB (FU...
I am using a STM32F767BITx LQFP208. I have to measure 12 channels. 6 channels measure the voltage and 6 other channels measure the intensity. Samples from voltage and insitensities shall be done as simultaneously as possible.I am using ADC1(voltage) ...
I am having the exact issue experienced by Carole Jacquinot in this post: https://community.st.com/s/question/0D50X00009XkWxASAV/why-there-is-an-increased-current-consumption-after-3-minutes-during-stop-mode-with-rtc-with-hal-driverSome additional in...
Hello everyone, I am trying to use STM32H725 processor with NAND FLASH 25N01GV. The installation seems successful. But sector erase always fails with the same error Status Register(0xC0) = 0x04 (EFAIL - Erase Failure )1. JEDEC ID read successful.W25X...
Hello, I am trying to built an applicaiton on STM32WB55 MCUs that contains interrupts and many digital signals. My code working very fine on development board and I am trying to implement this code on custom STM32WB55 PCB. The Problem is vect...
Hi I already asked for multi channel ADC in STM32G030K8 PA0,PA2,PA5,PA9,PA11,PA12.while debugging I am getting all ADC values as same if I made one by one its working properly Can any one help how to proceed with that.
