Today I added a small page for the USART communication test program I use. Its a very simple implementation of the hardware USART capabilities of the Microchip PIC18F1220 micro controller. You can find the page here: USART communication (hardware).

And I have a long overdue site update to prove it! Im working on a Terrarium Project and one of my tasks is SPI communication. I wrote a quick page for it, you can find it here. As always comments are welcome.
