Both these chips are the Parallax P8X32A-Q44 purchased from the same vender (Mouser). The one on the left was purchased a month ago and the one on the right just arrived today. Anyone know if Parallax changed the etching?
Today I wrote some code to get the IEE Flip VFD working. It has a fairly simple protocol and only took a bit of tweaking to get it working. I wrote the demo code for my Prop Dev Stick and will be uploading the SPIN code later once I finish the feature set.
After this I will write some C code for the MSP430 LaunchPad and get that working. The screen supports a serial input mode which saves 8 I/O pins but requires more timing. I will try to get that working as well.
