What is kevopic?

kevopic (khepera evolutionary pic) is a Microchip-PIC-based turret for Khepera with plenty of general purpose I/Os. The 3rd revision of this board features a PIC18F6x20 with two RS232 ports. The first one is used for communication with a supervising PC (e.g. running goevo) while the second one is connected to the Khepera. The advantage of using such a configuration is that the Khepera doesn't need to be reprogrammed. The PIC can send Khepera commands using the standard ASCII protocol defined by K-Team (cf. Khepera documentation) while the communication with the supervising PC can use another (binary, more effective) protocol like the one used in current firmware and compatible with i.

kevopic can be used to interface whatever sensor or actuator by using its digital or analog ports. As a first example, hardware specifications for a linear camera (based on a TSL3301) are provided in the download section (see below).
