I am looking to write an a/d converter, rs232/bluetooth and rtc. I didn't see a lot in the forums on vps so I was wondering are they still a good idea and are they being used by the community ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=118487#m118552 Need assistance?

The only prog that I have seen, that is close to being a VP, is in the SX/B examples folder, it's a read only (Rx) UART. All other VPs are in asm, go to the Parallax.com download area and you will find the main VPs there. As for the A/D, in the Al Williams book, he has an example, of course it is in asm, but it is simple enough that you may be able to re-create it in SX/B (inline asm). I have been trying to dabble in this for quite some time, and it is not easy going.
