Flipper Zero: JavaScript Bit Banging SPI 8x8 Display
Currently JavaScript on the Flipper Zero does not support the SPI protocol. In this video we use the existing GPIO module (available in all custom firmware) to do bit banging of the data! We also use an inexpensive logic analyzer to analyze the signals (sampling at 16MS/s) from a working app to reverse engineer the data we need to send to the device.
