pico-ttx4

Hardware Emulated TTX4 IO

This currently will look exactly like the TTX4 USB input device I reversed here. At least, according to the linux tool lsusb.

Build instructions

1. Install CMake (at least version 3.13), and GCC cross compiler Debian:

sudo apt install cmake gcc-arm-none-eabi libnewlib-arm-none-eabi

Arch:

sudo pacman -S --noconfirm arm-none-eabi-gcc arm-none-eabi-newlib arm-none-eabi-binutils cmake gcc

2. Download the pico-sdk and set the PICO_SDK_PATH environment variable. Also set the variable in your .bashrc, .zshenv, or even /etc/environment for future use.

git clone https://github.com/raspberrypi/pico-sdk
cd pico-sdk
git submodule update --init
export PICO_SDK_PATH=$PWD
cd ..

3. Clone and build this repository

git clone https://github.com/Drewol/rp2040-gamecon
cd rp2040-gamecon
mkdir build
cd build
cmake ..
make

4. Upload the pico-ttx4.uf2 that was created in your build directory to the pico device by mounting the partition (see script below):

5. Find the disk to mount:

   sudo mkdir /mnt/pico
   sudo mount `sudo fdisk -l | grep 'W95 FAT16' | awk '{print $1}'` /mnt/pico
   sudo cp pico-ttx4.uf2 /mnt/pico
