The LA104 (often referred to as the e-Design LA104 or the "Logic Analyzer 104") is a pocket-sized powerhouse beloved by embedded systems engineers, hardware hackers, and electronics hobbyists. At its core, it is a 100MHz 8-channel logic analyzer, but its true potential is unlocked not by its stock firmware—but by the firmware work you put into it. for(int i=0; i<BUFFER_SIZE; i++) test_pattern[i] = (i &

Here are the three most active and useful firmware bases for LA104 firmware work : 4.1. DSLogic LA104 Firmware (DreamSourceLab) DreamSourceLab originally designed the DSLogic (a USB logic analyzer). Someone ported their firmware to the LA104 hardware. This firmware makes the LA104 appear as a DSLogic Pro to PulseView. At its core, it is a 100MHz 8-channel
