Re: Hardware SPI Problem
I think that sharing the same pins with the SD card should not be problem. There should be another problem.

Re: Hardware SPI Problem
Hello @jimmo
Actually my problem is Hardware SPI. It is not working in fast or slow mode that I even tried in 100KHz. Besides, SoftSPI works as expected.
I can stream camera data to LCD display but due to harware SPI problem it is too slow.

Hi, They do not answer about micropython. Their only concern is openmv project.
