Digital Port

Hi Ralph,

As you said PD5 is digital input port. but the port next to it is PE1 (TXD) port. i did programming on it & i m getting 8 V as output on it. so i think TXD is also digital output port, if so then how can i get 8 V as output on Digital port ?


I do not see how you have access to these 2 pins. I looked at the schematic for the BL2100 and it does not appear that PE1 goes to a connector available to you. The analog inputs are labelled ADC and the outputs are labelled DAC on page 3.1.1 of the user manual. Are you using the BL2100?
