The LA104 Logic Analyzer is a portable, 4-channel digital analysis tool whose utility is significantly defined by the firmware it runs. While the stock firmware provides basic protocol decoding (SPI, I2C, UART), community-driven alternatives like the Gabriel Valky (gabonator) firmware transform the device into a versatile multi-tool capable of RF protocol decoding, signal generation, and even MIDI playback. 1. Getting the Official LA104 Firmware to Work
Official Stock Firmware: Downloadable from the MiniDSO website. It handles basic digital signal capture at 100MSa/s and protocol decoding for standard interfaces.
