We are using STM32H723 on a custom board.Right now, we are not measuring RTC calibration, we just have a possibility for the user to manually insert values of CALM and CALP elements in RTC_CALR register. We want to inform the user about resulting fre...
Hi,I'm using 2 STM32F4 MCUs for Modbus TCP Server/Client implementation based on LWIP. One MCU as a Client and other one as a Server. I have connect both MCUs through D-Link DES-1016D ethernet switch.The problem is when I connect both MCUs directly (...
I have written a bootloader that is used to update the application code via a Modbus interface over USB.I'm still working on the code to start the bootloader when new firmware is to be uploaded to the custom board. My board has a buck and an inverti...
Hello.I am trying to learn about DMA with spi. I tried HAL library which worked fine for me, I tried the LL Examples (stm32L4x) provided in repository which worked fine when i am reading once with loopback. Now i am trying to use a full duplex master...
Hello forum members, I am currently working on a custom PCB based on the STM32U575ZIT6 microcontroller. I've encountered an issue when configuring PLL1 as the clock source – the code generates a hard fault. However, when selecting HSI or HSE as the s...
Hello ST Community,I've been troubleshooting an issue with writing to address using system Bootloader on the STM32U5A9J-DK. According to AN3155 Application Note, the data to be written during the 'Write to Memory Command' should be a multiple of 4 by...
Hello,I want to make a design with the ADC1283 where DVCC is powered by a 5V buck converter, and AVCC is powered off a 4.5V voltage regulator (that's powered off the buck converter). Is this possible?I can't tell whether DVCC and AVCC are allowed to ...
Hello all, I have stm32L5 and stm32U5 board and I need to act one of then as mouse but I couldn't . so could you help me to do this or send example code because I search but I don't find any example best regards.
Hello everybody, I designed a touch sensor whith the STM32F042 MCU but after a week of constant testing and experimenting still not working. First the problem was that the TSC always get in the too much count error, after I thought that maybe the cap...
The MCU is STM32G031J6 on a STM32G0316-DISCO board.The maximum software pin toggling speed I am able to achieve is about 0.7 us.It looks a bit slow for a M0+ running at 48 mhz.Looking at listing file, there is no library overhead (I am using LL).Can ...
