PSoc5 Port of Grbl CNC Controller
This is a port of the amazing Grbl CNC Controller firmware to the Cypress PSoC 5 CPU. Grbl is targeted at the Atmel ATMega328P and ATMega2650 8 bit CPUs. The PSoC 5 is a much more powerful CPU and is a mixed signal processor.
This version uses the native USB feature of the PSoC. This removes the need for a separate USB/TTL device and allows for very high transfer rates. You can choose any baud rate in your sender program up to 2Mbps.
