Hello friends,

I am using LPC-Link ii board for my project. In the schematic diagram of the board, I saw EXP_ADC0_DAC pin. I know ADC0 and DAC are connected internally and ADC0 is P4.3 and DAC is P4.4 . However I was wondering if I can use EXP_ADC0_DAC pin for DAC operation or not?

Please help me regarding this.

Hi,

Yes the EXP_ADC0_DAC pin can be used for ADC functionality or DAC functionality.

Thanks,

Hi,

I just want to confirm one more time. I tried to use EXP_ADC_DAC of LPC-link2 board for DAC purpose, it doesn't work. You can find part of my code here . Are you sure I can use this pin for DAC? please help me regarding this.
