#spi #lora #eink We will learn about SPI serial communication by trying to connect 2 peripherals to the microcontroller. Both the peripherals support the SPI protocol which has some properties such as frequency, data order, and data mode. We will analyze the 4 pins through the logic analyzer and examine the Arduino firmware to ensure they are not conflicting. ⏰ TIMESTAMPS 0:00 Intro 1:24 SPI Pins - Data in, data out, clock, chip select 4:20 Firmware - pins, enable, frequency, mode 8:35 Multiple SPI peripherals ‣ Some links below are affiliate.
