I'm using an analog sensor to get reading based on the distance between the object detected and the sensor itself. So far based on all the documentation as well as examples I have read on the A/D converter with the LPC2119, this was the best I could come up with. The analog sensor is connected to Port 0.27 which is one of the A/D channel ports. I just need some further assistance with m...

Hi, we have build a system with the LPC2119, where we connect a 5V Signal to a GPIO. Now when the system starts, the 5V is present a little bit earlier than the 3.3V. Could this be a problem for the device, because in the Limiting Values for this device the 5V tolerance is only specified when the 3.3V is present. Another question

Where is it hidden in the Phillips documentation what io type each of the pins are? I'm using a lpc2119 and I guess I expect P0.X gpio pins to have pullups. Looks like I'm wrong on pins I'm trying to use. But don't know where to find the info to confirm. The only pins even mentioned are P0.2 and P0.3 as open drain. So what are all the others? I'm looking at LPC2119_2129-03.pdf.
