Hi,I am using stm32h745. I want to check the integrity of flash by checking crc checksum of the code in flash by storing the crc to last 4 bytes of flash. During image integrity check the calculated crc and stored crc need to compare. For this how sh...
Hello I have RTC problem using LSI clock. This issue don't work RTC.I see that SSR is change. but don't change TR. But When IAR debug configure, RTC is working. My MCU is STM32F429My Config code is blewCould you find a wrong initialize code? void Sy...
I'm trying to acquire data from 3 sensor simultaneously using Triple Mode. Im using TIM 2 TRGO as a trigger for starting ADC. my data are getting correctly generated in the respective DR registers of ADCs but not in Common register ADC->CDR where it ...
Simple question, I'm trying to locate a user manual for STM32U5xx HAL library but can't find it. The official STM32U5 ST page doesn't provide it. And neither does the STM32CubeU5. Does this mean it doesn't exit yet? But if code is there, then it shou...
Hi ,While checking the "Flash recommended number of wait state for programming delay" list for my project on STM32H723 target, observed the list is not up to 550Mhz. It's showing VOS0(boost mode) [ 70Mzh, 140Mhz, 210Mhz, 275Mhz] , It's listing max LA...
Hello all, I have a fundamental question, I hope it is easy for somebody who has done this before.I started a brand new project for a STM32H7A3VITxQ on Firmware package FW_H7 V1.11.2STM32CubeIDEVersion: 1.16.0Build: 21983_20240628_1741 (UTC)Updated t...
Hi, we are working with a STM32F217 and the RMII bus.In the two documents reported I see an inconsistency on the diagrams (on the one hand rising edge sampling, on the other falling edge). Which one is correct for my chip?RM0033 Figure 328 Reference ...
Dear allI'm starting a design with the STM32L412R8I (or maybe STM32L412RBI6) and I cannot find the VBUS dedicated pin in the datasheet nor in the manual. In this design the USB will be always device (no OTG)Is it enough to have VDDUSB powered to de...
I'm using ADC1 to measure the Temperature Sensor channel and the Vrefint channel. I expect those to vary very slowly and I am in not in a hurry so I am maximizing the sampling time. These are my settings in STM32CubeIDE:It generates the following in ...
This is a question about SPI communication.There is an NSS pin for SPI communication, but is it okay to use GPIO instead of the NSS pin when there is one master and one slave?We don't quite understand the role of NSS. I think it will be useful when t...
