Description

Fits on the RODYNE Motor Controller Motherboard.

Dauughter board is seperated from motherboard to allow different MCU and Resolvers to be made if required.

The above project uses a Microchip 100Mhz dsPIC which has several well documented designs for motor control and the Texas Instruments PGA411 Resolver which interfaces the more common magnetic resolver found on the Nissan Leaf and many of the more common EV Motors and converts it to a Quadrature encoder signal which the dsPIC can directly process.

I will be working on the code for the MCU over the coming years and will post updates on my web site

Feel Free to substitute your favourite MCU :-)

Note this is the second revision with corrected pin dimensions and spacings.

Usual disclaimer. This is public domain and while every effort has been made to ensure the circuit is accurate, mistakes may occur and it is up to the system builder to ensure it works, refer to the dsPIC and PGA411 datasheets and reference designs (below) for information on operation.
