WebMar 31, 2024 · One handy use of the SPI flash is to store data, like datalogging sensor readings. The fatfs_datalogging example shows basic file writing/datalogging. Open the example in the Arduino IDE and upload it to your Feather M0 board. Then open the serial monitor at 115200 baud. WebUse 10 for SPI0, 20 for SPI1, any GPIO pin for bitbang. :param sclk: Clock, use 11 for SPI0, 21 for SPI1, any GPIO pin for bitbang. :param ce: GPIO to use for Chip select. Can be any free GPIO pin. Warning: This will slow down the bus significantly. Note: The hardware CE0 and CE1 are not used :param bus_speed_hz: Speed of the hardware SPI bus.

WebSPI is a full-duplex interface; both main and subnode can send data at the same time via the MOSI and MISO lines respectively. During SPI communication, the data is simultaneously transmitted (shifted out serially onto the MOSI/SDO bus) and received (the data on the bus (MISO/SDI) is sampled or read in). WebCircuitPython is based on Python. Python is the fastest growing programming language. It's taught in schools and universities.
