La104 Firmware Work

Feature Proposal: The "Open LA104" Firmware Initiative

Project: LA104 Digital Oscilloscope / Logic Analyzer Focus: Custom Firmware Development & Hardware Unlocking Status: Ongoing Community Development

Then compile:

#pragma config POSCMOD = XT, FNOSC = PRIPLL, FPLLIDIV = DIV_2, FPLLMUL = MUL_40, FPLLODIV = DIV_1

The old firmware handled sampling well enough at 1 MHz, but at 5 MHz it stutters like a worn cassette tape. Glitches appear in the captured waveforms — phantom spikes, dropped edges, timing drift. Somewhere in the assembly, a race condition hides like a bad ground. la104 firmware work

• MCU: STM32F401CC (Cortex-M4, 84MHz typically).
• FPGA: Lattice LCMXO2-1200HC-4MG132.
• Memory: 8MB SDRAM.
• USB: USB 2.0 High Speed (internal PHY).

Standard firmware is often replaced with community-driven projects that add features like: I2C/SPI/UART Decoding: Real-time protocol analysis. Oscilloscope Mode: Basic analog wave viewing. Signal Generator: Outputting PWM or clock signals. Common Sources: Official Minidso Forum: For factory updates. The old firmware handled sampling well enough at

: It utilizes a 2.8-inch ILI9341 LCD (320x240) and provides 8MB of internal flash storage for apps and data captures. Key Firmware Projects LA104 pocket logic analyser operating system - GitHub MCU: STM32F401CC (Cortex-M4, 84MHz typically)
