# μLA: Micro Logic Analyzer
SUMP/OLS compatible logic analyzer firmware for [RP2040](https://en.wikipedia.org/wiki/RP2040) based boards.
## Features
* 16 channels
* 100 MHz sampling rate, 1 sample per sys tick
* 200 KB sample memory
* Fast triggers using PIO
* Input channels mapped to GPIO 0-15
## Supported hardware
* [Raspberry Pi Pico](https://www.raspberrypi.com/products/raspberry-pi-pico)
* [uPico](https://github.com/dotcypress/upico)
* Virtually all RP2040 based boards with USB connection and GPIO 0-15 available
* Bring your own RP2040 hardware with proper frontend and protection
## Installation
1. Download latest firmware build from [Releases page](https://github.com/dotcypress/ula/releases)
2. Hold the BOOTSEL button while connecting your board to the computer
3. Copy firmware file downloaded earlier to the RPi-RP2 disk
4. Use PulseView of SigrokCli to connect to probe
5. Enjoy
## Client software
### PulseView
[PulseView](https://sigrok.org/wiki/PulseView) is a Qt based logic analyzer GUI for sigrok.
Select `Openbench Logic Sniffer & SUMP compatible` protocol when connecting to μLA.

### SigrokCli
[SigrokCli](https://sigrok.org/wiki/Sigrok-cli) is a command-line frontend for sigrok.
Scan for devices
```
$ sigrok-cli -d ols:conn=/dev/tty.usbmodem_ula_1 --scan
The following devices were found:

## Building firmware
1. Install rustup by following the instructions at https://rustup.rs
2. Install Cortex-M0, M0+, and M1 (ARMv6-M architecture) target: `rustup target add thumbv6m-none-eabi`
3. Install LLVM tools: `rustup component add llvm-tools-preview`
4. Install cargo-binutils: `cargo install cargo-binutils` (Note: on some Linux distros (e.g. Ubuntu) you may need to install the packages build-essential, gcc-arm-none-eabi, libssl-dev and pkg-config prior to installing cargo-binutils)
5. Install elf2uf2: `cargo install elf2uf2-rs`
6. Clone this repo: `git clone [email protected]:dotcypress/ula.git && cd ula`
7. Hold the BOOTSEL button while connecting your board to the computer
8. Flash microcontroller: `cargo run --release`
