Hello everyone, I have enabled an spi1 port on a STM32G473CET6 as a slave and am using a raspberry pi as a master.I have verified with known packets to ensure I have implemented the correct crc algorithm on the raspberry pi both in transmission and r...

Hello everyone,I have setup my stm32 to use interrupts and have enabled them to work on spi1 and all 4 i2c ports. The relevance of the i2c ports is that they run continuously and may call the interrupt service routine while the spi one is being calle...

When you say fed through you mean when the callback is entered? The photos of the registers are of when the stm32 had just entered it. I've tried a few more times while sending and receiving a known packet because as far as I can tell there is no way...

Ok thank you, I will shorten the interconnects and twist them together. To be clear are you saying having a separate line for each signal line to ground? I'm not sure how to implement this because the signals go directly to the MCU so I only have one...

Thanks for your suggestions. As a GPIO output the MISO pin works perfectly. I did 3 tests, the first two were at 50kHz and gave wrong results but indicate a bit offset which accumulates and destroys the whole miso packet. In bold are the preamble to ...

With this code as the whole main I still got no response. It prints "Writing" twice before the master even sends anything but I don't see anything on the logic analyzer. alt_main() is called just before the while(1) in the normal main() uint8_t spi_t...
