Hydraulic Pump Motor Control Options

[tfmacz]

Hi Iain
is is possible you could share the pic hex files for both the H-Bridge drive pics and the pump switch pic.

I can program pic's and a couple local guys would like to play with you design.

Thanks for sharing

The pump switch is the bottom PIC chip. Not sure if the diagram will be big enough as an attachment.
