When we were working on a small batch, we encountered a situation where one of about 100 pcbs would frequently trigger a hardfault. We found that the problem would recur when the cache was enabled. When the mpu was enabled and configured correctly, i...
Heyho,just checking the L162 for a new project, then found that the ADC can only be clocked by the HSI.Is that correct?If yes, why?My experience with HSI (and other RC-oscillators) is that it is "mediocre" at best, rather inaccurate and jitters like ...
Hello Community For some reason, my post from yesterday did not go through and was marked as spam. I'm not interested in moaning about it right now, as I have managed to brick my custom board, designed with STM32H743XI and would be more interested in...
I am using STM32H723 and have implemented WWDG. Below is my configuration: Are there possibility that when the system resets due to watchdog it would not trigger its ISR.
We have implemented a total of five push buttons—two connected to Port E and three connected to Port M. The GPIOs of Port E are functioning correctly. However, the GPIOs of the push buttons on Port M are not being detected properly by the MCU.Even wh...
Hello,I am writing & erasing flash during operation, and this seems to cause a bus stall which prohibits all execution from flash during these operations.AN4808 seems to indicate that if you use a dual-bank device you can avoid this by executing out ...
Hello,I’m trying to setup the PSSI interface on the STM32H523RETx to transmit data. I cannot find how is the PSSI_PDCK configure. Neither in the clock tree nor in the RCC register the PSSI clock can be configured (except for enabling it). In RM0481 t...
Hello everyone In my application using an STM32H7, I noticed that the VBAT pin, with VDD off, draws 1.9 mA. This is excessive current draw.I'm using a CR2032 battery in series with a 100R battery connected to the microcontroller's VBAT pin.What could...
I'm currently using single 16-bit ADC, my requirement is to have ADC conversion error less than 1mV.I'm using the ADC with DMA. I'm a beginner, currently getting 1-2mV error and it is not constant too. #define SCALE (3300.0f/65535.0f) uint16_t adc_...
