We are using a Bitsy Plus with Windows CE to drive a vehicle display system. We are currently trying to switch inverters from the LS520 to an Applied Concepts AC2-12-1128. Unfortunately, the AC2 inverter expects the BACKLIGHT PWM and BACKLIGHT ON control signals to be active high whereas the LS520 expects active low. The Bitsy is providing active low signals currently. How is this option changed on the Bitsy?
Hi Jessica. Here are a couple options available to you:
Hardwired Solution The quickest is to hard-wire your backlight on for now. This sometimes is as simple as disconnecting the signals from the inverter. We describe this for the LS520 at topic 524.
Startup App You can also write a quick app that initializes the backlight the way you need it. Backlight code for CE is posted at topic 451.
Custom ADSmartIO Build Finally, we can create a custom build of the ADSmartIO firmware that initializes the backlight the way you need it (as we did for the Bitsy). Drop us a note if this is an option you want to pursue.
