How to read SPI correctly?

I use Nucleo board (STM32L053R8) to connect SPI slave. The SPI command had been sent to slave correctly, and slave also return the expected value (0x2C). But Nucleo SPI master cannot get the return data correctly. The RXNE is raised without problem, ...

STM32H7 SAI + DMA + Cache enabled: nothing works as before

Hello, I am working on a project where I implemented various peripherals including a SAI configured in DMA mode. I have defined a 1024 samples buffer and used the Half and Full callbacks to fill it. Everything worked perfectly. However, I quickly rea...

Resolved! STM32F103 SPI DMA slave mode sends first byte twice

I have an STM32F103 configured in slave mode using NSS for slave select and using DMA. I'm using 8 bit mode. When the master starts clocking the STM32F103 it always shifts out the first byte in the buffer twice. So rather than seeing 0xF0, 0xF1, 0xF2...

LSE false enabled, PC14 wrong reading

We discovered spurious Errors (every half a year) on reading out the GPIO Pin PC14 on a STM32F427ZIT6.The Pinis not connected on the PCB itself.Is configured as Input with PullUpAnd reads in perfectly the High state from the PullUp in 99.99% of the c...

Resolved! Hardfault on ADC voltage change

Hello,I have a strange problem on an STM32G071. I get ADC values every 25 ms from ADC1 channel 0 to 3 without DMA as speed is no issue. Strangely when one of the canels reaches about 1.2 V the CPU sometimes goes in a hard fault lock. There is a poten...
