Overview
GitHub repository: https://github.com/geekscape/ohmc2022-firmware
FPGA gateware and firmware for the Rockling FPGA SAO (codec branch) currently supports the Theremin input (dual input frequency counters), the FPGA running a soft RISC-V processor and hardware peripherals. However, the STGL-5000 audio codec IC integration is still a work-in-progress.
Set-up USB hot-plug UDEV rules (for Linux only)
When the Rockling is connected to the computer's USB port, the dynamically created device file /dev/bus/usb/001/... will need to have the correct permissions set by the UDEV rules.
From FOMU workshop instructions
sudo groupadd plugdev sudo usermod -a -G plugdev $USER
Log out and log in again
sudo bash
vi /etc/group # Add users to "plugdev:x:46:$USER"
vi /etc/udev/rules.d/99-fomu.rules
SUBSYSTEM=="usb", ATTRS{idVendor}=="1209", ATTRS{idProduct}=="5bf0", MODE="0664", GROUP="plugdev"
udevadm control --reload-rules
udevadm trigger
