Well, the brush motor Hbridges are supported as well (7I30,7I40,7I29) only difference with these and 7I33 is: Daughter card Optimum PWM mode 7I33(T,TA) PDM 6 MHz 7I30 Straight PWM ~20 KHz 7I40 Straight PWM ~20..50 KHz 7I29 Straight PWM ~20 KHz 7I48 is different in 2 ways, it uses the multiplexed encoder module and uses up/down PWM mode The driver does not currently support the muxed encoders (but support should be trivial, the muxed encoders have the same register set as normal encoders, just a different base address and tag so the driver knows the difference) Also one additional output pin needs to be enabled (the "mux" pin) for muxed encoders. 7I65 is also not supported by the driver yet, it has both muxed encoders and SPI ADCs, DACs, and Enables. SPI support is a fairly good sized project, but I think it's manageble if the daughter card specific SPI setup and SPI data munging is done in a HAL component, and just the low level bulk data I/O done by the driver. > > Will the: > 7i48 (6 channel servo card) or > 7i65 8 channel card > be supported in the nearish future? > > I will add the info I get to the wiki. > Thanks > Chris M > > > _________________________________________________________________ > Windows Live: Keep your friends up to date with what you do online. > http://go.microsoft.com/?linkid=9691815 Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
