What do you mean? Is it that the software takes the average of two or more 8-bit quantities and then outputs them to one channel? (It would make the program a lot slower). Does the circuit contain anything for timing? For example a custom interrupt or a DMA or a buffer that you can fill up and wait for it to empty. It would be much easier than fiddling with line interrupts and so on to get the accurate timing from within the machine code. It would also make faster rates possible. imc
