Hello Bruce, hmm you specifically mean from the PIN3.3 right? Which is my TX. Which is odd because I am not getting any signal at all from it. Although when I set the appropriate breakpoints, I get correct results for the values 'i' and 'j' under 'Watched Expressions'. Which is that 'i' changes between 0 & 1 depending on HighByte & LowByte and that 'j' counts down from 32767. So that leads me to think that I must have missed a specific line/setting to enable the sending of signals. I have also tested to make sure the UART interface works by connecting TXD & RXD with the jumper and testing if the board echoes what I type into HyperTerminal.. P.S. I have discovered that the type INT must be changed accordingly since the boards have different native sizes so I changed 'signed int j' and 'int i' to corresponding int16_t j & int16_t i
