The data sheet isn't specific, apart from one diagram Figure 13 that shows IO's box with an arrow from VDD that then connects to a level shifter to the core domain.Please advise. A real handy feature would be to alternative voltage IO for the SPI's...

Hi, i'm using my STM32F7 nucleo 144 and i'm learning about timer encoder mode and i follow the example in the datasheet but when i check the CNT register it oscillates in the same values and if i use the A0-A1 pins the encoder works bad, can somebody...
Hello everyone, I'm trying to build a sensor device that uses stm32l452re as MCU, I need to save my data to sd card using sdmmc features to access it. i using 4bit mode and clock divide 128, but unfortunately, my sd card sometimes corrupted and i nee...
I have a created a circuit from the Sensortile reference design and the MCU and the step down transformer both overheat, I am thinking the BGA pattern on the STM32 is off and there is a short drawing alot of current? BOOT0 is groundReset is pulled lo...
I have STM32L452RET6P running at 1.8V, 24MHz. I am using nine ADC1 channels and am getting a very low value (about half) on ADC1-1 (PC0).All inputs are set up the same way, with an RC filter (33kOhm/0.1uF). The sampling rate cycle is 12.5 at 10bits, ...
I need to confirm my understanding. Say that my STM32H7 SPI is setup as Slave and that it processes the incoming SPI data byte per byte in interruption. It is very likely to happen that the SPI throughput is faster than the SPI interrupt handler dura...
Hello everyone i am using CAN bus to connect two stm32 boards, i would like to know does anyone of you know how does the CAN memory works? is it DMA or what exactly? i couldn't manage to find anyuthing on the internet and i really hope one of you can...
hello everyone, i would like to know how can i transfer data from CAN Bus to DMA memory on stm32f4 board on HAL Library? also i want to make sure that the CAN access memory is it DMA or somethign else?can you please explain to me how? or if you hav...
Hello, I try to make an UART communication between Nucleo STM32F030RE and a STM32F030K6 mounted on a custom pcb.sends from NUCLEO to STM32F030K6 is OKReceive from STM32F030K6 is ok sends from STM32F030K6 to NUCLEO is OK (i can check it and decode tha...
