It's my understanding that it is a bad idea to mix lead-free and leaded solder, and that it can cause cracks.I'm using a TFBGA100 package on an STM32H7 and have some long-term reliability requirements. In order to avoid tin-whiskers, I was considerin...
In my project it can happen, that the LSE gets blocked due to a CSS failure detection after repowering. I found this good article on the ST community which maches alomost with my case: https://community.st.com/t5/stm32-mcus-products/lse-fault-recover...
I read RCC RSR to determine the cause of reset. It is not clear to me the purpose of RMVF bit. I guess it resets the other flags but why would I want that ? I wonder if I am missing something.
Posted on March 23, 2017 at 12:06i search in google and i can't find any adc external trigger example code i found timer trigger only.i want adc start conversion when external pulse found.i want any example code
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) ...
