Resolved! RM0455 STM32H7A/B: Reset state of SYSCFG_PMCR incorrect?
RM0455, rev. 6, says reset state of SYSCFG_PMCR is 0x0F00 0000.But STM32H7A3ZIT6Q, rev. Z, shows 0x0300 0000 instead, i.e. PC2 and PC3 switches closed. not open. Does this depend on package as PC2 and PC3 are not bonded out for this particular packag...
Not able to update internal RTC in STM32F373
Hi, I made a project for only internal RTC. It worked with LSI and not with LSE. Then I integrated RTC in current project which has various other features. It is not working. I am getting zero readings. RTC initialization, get tim...
No device found on target ERROR
I have a STM32NUCLEOF411RE. It was working well until today. Now my pc can not recognize it. It says "No device found on target.". Also when I connect my board the processor becomes too hot in a few seconds. However, when power it with 5V it does not...
Issue in STANDBY Mode in stm32f746g discovery board.
Hi everyone,I am trying to implement the STANDBY mode in stm32f746g board using the system wakeup pin PI11 (user push button). The issue is that once I press the button, the controller automatically wakes up from the STANDBY mode.I have attached my c...
STM32H743 Interface with external ADC & DAC for closed loop control
I wish to build a classical closed loop controller based on a STM32H743 interfaced via SPI to an external 16bit ADC and to a 16bit DAC. The MCU is supposed to read an ADC sample, feeding a controller routine (for example implementing a standard PID c...
