Robotics and Sensors Using Erlang
summary
GRiSP boots a cross‑compiled BEAM on bare metal and runs an embedded Erlang VM with a GRiSP runtime, a 300 MHz ARM Cortex‑M7, 64 MB RAM and microSD storage; SPI/I2C/UART/Pmod drivers are implemented in C with Erlang bindings and the team demos an accelerometer‑to‑LED demo and a simple wheeled robot that mostly drives; current limits are slow SD reads, 2× slow timers and Wi‑Fi packet loss, and planned work adds DMA, interrupts and more Pmod drivers.
