Hi, I'm doing a project with a 80C32 processor. I'm lacking, however, interrupts. Is there a (tricky) way to have more than the standard provided interrupts at your disposal? --Geert
If you load a timer with 0xffff and use the external input (counter) configuration, you will get an interrupt when the pin toggles. This can be done with all timers. With this method the interrupts can be edge, with the above hardware suggestion, they have to be level. A third possiblity is to use a derivative with comparators (philips LPC (<$1), Cygnal) and use the comparator interrupts. A fourth is to 'play' with the PCA/CCA. as a fifth I believe you can trick the UART, IIC and SPI interface interrupts to act as external interrupts. Erik
