La104 Firmware Work
To help find the right version or troubleshoot your setup, please share a few details:
The LA104 is no longer in active production at some major distributors, but the community firmware ensures the device remains useful. The open-source nature means that as long as developers maintain interest, new features can be added and compatibility expanded.
The user selects the sampling rate, trigger conditions (rising edge, falling edge, or high/low states), and buffer depth via the physical buttons.

The LA104 is a popular, pocket-sized 4-channel digital logic analyzer that relies heavily on community-driven firmware to reach its full potential. While the stock factory software provides basic functions, upgrading or changing the firmware unlocks advanced protocol decoding, user interface improvements, and entirely new instrument modes like oscilloscopes or signal generators.
Drag and drop your downloaded .hex or .bin file directly into this folder. Step 4: Verify the Installation
If you are installing a custom operating system like Gabonator's, you may need to format the internal 8MB flash drive separately: After flashing the OS file, power the device on normally. Connect it to your PC. It should appear as a standard FAT-formatted 8MB drive If prompted, format the drive as (not FAT32 or NTFS). Copy the application files (usually files from an approot.zip archive) directly onto this drive. Troubleshooting Tips Mac/Linux Users: To help find the right version or troubleshoot
100 MSa/s max sampling rate with a minimum detectable pulse width of 10 ns. Storage: 8 MB onboard flash memory. Display: 2.8-inch TFT LCD with 320x240 pixel resolution. Critical Limitations of Stock Firmware
The MCU processes the raw binary data and draws the waveforms on the 2.8-inch color LCD screen. Expanding Capabilities with Custom Firmware
: Modern firmware configurations let you bridge the device directly to a desktop web browser using WebUSB, enabling real-time data streaming and a vastly larger screen interface.

This work transforms the LA104 from a "toy" into a testament to what community-driven engineering can achieve.
What is your shown on the splash screen?
Copying files directly to the DFU drive on OSX can fail. Users are advised to use the dfuload tool to correctly simulate the flashing process.
A step-by-step tutorial is provided in the repository at resources/tutorial_building . The build process uses standard ARM GCC toolchains and requires minimal setup beyond installing dependencies.
