I tried PortF by changing i2c.lib a little and I was able to use pins 20 and 21 but voltage level varies only 4.7 V to 2.5 V and instead of 0-5 V . I tried several different pullup resistors but still the source voltage won't go to zero. > Are there any information how ports are mapped to BL2600 pins ? I can find RCM3000 port diagrams but there are no such information for BL2600. For example what is the port connected to pins DIN24-DIN32 and can I use those pins to I2c ? > > > Any help would be greatly appreciated. > Those are input pins only as they have 27k series resistors on them. Check the schematic for pins you might be able to use: http://ftp1.digi.com/support/documentation/0900195_e.pdf A quick look and I don't see any that are I/O. -- ------------------------------------------ Scott G.
