to create code for uPSD? Is there perhaps a tutorial available to do so? I tried to convert one of the example programs (PWM-ADC) that runs on the evaluation board - it compiles without error but doesn't run on the board at all so I'm a bit stuck there! Keil's compiler whilst good, well tested and supported is far too expensive for what you get so I don't think I will get the capital to purchase it for this project. As SDCC looks like a good compiler with an active user base I was wondering if anyone had any experience with this compiler and the uPSD32xx family.
