3KG Sumo Controller

3KG Sumo Controller
- A motion controller developed to read 2 RC servo signals and operate a pair DC motors by way of dual H bridges.

- Two variants are being developed, one based on the dsPIC30F4011, the other based on the ATmega324.

Features: * DSPIC30F4011 Controller (48Kbyte Flash, 2Kbytes of Ram) * Dual MC33926 H-Bridges (5A Peak, 3A continuous per motor) * 12 external I/O (including up to 6 A/D inputs and a hardware UART) * Fully functional demo code provided for RC signal decoding and motor control, written using free Microchip C30 compiler

Software Library Revision 0.1 January 10, 2011

NOTE : DO NOT USE C30 v3.25. Use an older or a newer version. V3.25 contains a bug in the printf library that will cause an out-of-memory issue
