Web11. jan 2024 · Let's do simple math: you drive card at 33 MHz, without considering the control overhead each clock cycle is one bit, thus to transfer a byte in SPI mode (single wire) you will need 8 clocks, thus 33/8 = 4,125 million bytes per second. Source, page A-2. Thus ideally SPI allows you transferring 1024 bytes in 248 us, which seem to be well below 1 ms. WebIn the SPI protocol, you get one byte back for every one you send. If you are not interested in the response from a device, you can just ignore the return bytes.
