STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
We encountered an issue with the SPI3 peripheral on F4xx and F7xx series chips where the RXNE bit of the status register would be set right after enabling the SPI peripheral after re-configuring it.This is clearly impossible as no transaction is perf...
Hello,After setting up a 4 channel read with DMA, I ran into the problem, that the value of the internal temperature sensor seemed to not change at all. The values of the read out potentiometer however were plausible.So I wanted to check all used cha...
Hi There,I have searched a lot about the HAL_I2C_Mem_Write_DMA problem and seems like i have not found anywhere else this issue has been solved.Can anyone contribute if someone has solved it. Thanks
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...
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...
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...
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...
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:
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...
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...
