That means you MUST have a regulated power supply. Also, where is your clock? Did you setup the chip to run on the internal RC oscillator? If so, you do know that runs at something between 3 and 5 KHz, not the standard Mhz right? If you want fast, you must also supply the clock. Read the datasheet. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=243374#m243420 Need assistance?
