WebJul 23, 2014 · SPI is a fully synchronous serial protocol. For every clock cycle one bit is transferred. There is, therefore. a 1:1 relationship between bits per second and hertz. A … WebMar 7, 2024 · In summary, bandwidth is the partial amount of throughput allocated to a particular connection; but because the whole SPI port is dedicated only to the SRAM, it's difficult to think about this concept. If I were to throw in another SPI device, would they share an equal amount of bandwidth or will one take more of a priority if its used more often?
WebNov 17, 2024 · SPI bandwidth According to this answer, the SPI can run at 125 MHz, giving a maximum bandwidth of 15.625 MB/s (125/8 bits). Bandwidth conclusion The GPIO method using one full core at 100% can be almost 3 times faster than the SPI, but since the SPI is driven by DMA, it will use much less CPU.
