Resolved! STM32h7b0 - System memory bootloader AN2606
Hi, I'm having issues on our custom board jumping to the system memory bootrom.Likely i have a software issue but would like to clarify the system memory address for the bootloader. This is usually listed in AN2606 but there is no explicit mention of...
Resolved! Countermeasure of hardware noise for software interrupt GPIO-EXTI line
I'm a beginner at STM processor, and I'm trying programming software interrupt using GPIO port as EXTI line at STM32L4R5QI(STM32L4+ series) processor.Then, I was wondering when I was reading the reference manual of STM32L4+ series. It seems that the...
Resolved! How do I change the Baud rate of a UART/USART whilst running?
I've followed some answers from a post here:https://stackoverflow.com/questions/57283327/how-to-change-the-uart-baud-rate-after-running-on-stm32-boardBut still can't seem to get the baud rate to change. Has anyone had any luck trying to dynamically c...
Regarding Volatge Control in STM32L562CET6
Hi all, I have working on USBPD Sink project in that ,I have been struck in the part of reading the voltage from the STM32L562CET6(Customized Board)before this process I have done the same project in STM32L562E-DK , What I need to do actuall...
Measure STM32F373 core temperature
Hi,I was measuring the STM32F373 core temperature.It seems that the core is 56°C while the environment is 23°C, no housing.Is the 56°C a reasonable temperature? It looks quite high to me.I used the settings below:
Resolved! Mixing HAL and Direct Register Manipulation
Hello. I am writing a code to read ADC data from an AC voltage sensor. I used HAL to initialize ADC 1 and USART2 for checking the values in Putty. However, I would like to use direct register manipulation to send data to USART6 so that it can transmi...
Resolved! Sleep mode, GPIOs and RCC_AHB2LPENR - STM32H5, EXTI wakeup sources
HelloWhat will happen with the IOs when MCU is put to Sleep mode (one of power modes in PWR) and register bits in RCC_AHB2LPENR for each GPIO-block are reset? When bits are reset, the peripheral clock is disabled during Sleep mode.Can the IOs still b...
