There is a problem with using printf like this and that is: stdout is line buffered. The 'b''s won't show until a newline is output or fflush is called. That's why I used fputc initially. If you do this with the 'pio mode' writing, you should do this for all methods an all chips for constistent behaviour, so that is why I commented it out initially.
Ah OK. I'll drop that part. Did you have time to test with the while (generic_spi_read_status_register() & .._WIP) enabled? It would be more correct to have it enabled. Regards, Carl-Daniel
