Hi community,since I cannot find a suitable LL-driver for reading register with 16bits address, here is my experiment.the nfc tag init function: the ReadID funciton is called, in background is GetICREF function.in low level the BSP_I2C2_Read16 functi...

Hi @tjaekel good news!!!it works with this kind of CS signal:the CS signal keeps always active until the last transfer session.not works, when just set CS active for every transfer session like this:***************************************************...

just found the peaks can be eliminated by set the pin speed to LOWthe data should be 0xC0 and 0x80, but both are recognised as 0xE0...

Hi @tjaekel Thanks for reply.the first byte is 0xC0, which will be sent to display.this is capture on Raspberry Pi, it also has a peak, but it doesn´t matter.these are the captures on my board, the data will be recognised as 0xE0 or 0x60. Of course, ...

new findings:with this setting LL_SPI_SetDataWidth(BSP_SPI2, LL_SPI_DATAWIDTH_8BIT);the data is actually 9 bits
