propeller starter kit and uoled-128-gmd1
I'm having a problem getting this display to function. I have it connected to vdd and vss. I have a 1k pullup resistor to vdd on the rx line. p6->rx, p7->tx,p5->RE. I can't get either of the objects from the parallax object exchange to function. the screen displays the 4d systems logo and scrolls and that's it. If I toggle p5 it will reset and display logo again. I bought a 1gb microSD card(from newegg.com) it is a kingston that looks identical to the one sold by parallax. I loaded some bmp files and shunted the pins on the back, but nothing happened. What exactly is required to use this display on the propeller. One of the uoled-128 demo's in the exchange use fullduplexserial which needs timing.spin, but the only reference to the usage of timing.spin that I can find is a 50ms wait state, so I replaced that line with waitcnt(250_000+ cnt) because I can't find timing.spin anywhere. I have no idea what's going on with this thing. The only thing I managed to accomplish is reading sony ir codes from a playstation2 remote and from the remote supplied with the IR kit. I have some cool projects I want to accomplish, but I'm new to micros in general and this is a major stumbling block for me. Anybody have schematics or code to try. I don't care if it only displays one letter, as long as it does something other than a factory logo.

Do you have a Windows PC and a Prop Plug?

My version of fullduplexserial doesn't reaquire and other objects, are you sure you have the right one?
The demo code provided with the oled obect should work, it works for me.· The only other thing required is the clock object.
