Using Max 10 ADC pins for digital signal

We used 8 channels of the ADC + TSD for analog signal conversion, but one channel needs to be changed to a digital input (PWM signal). Initial thought was to free that ADC pin and use it as a digital...

Hi Fan Xiong,

Yes, apologize that it cannot be used for both analog and digital pin simultaneously. Since it cannot be used simultaneously, the only way is to have digital pin placed on the other I/O pin or you change the FPGA image when you want to have that pin as digital I/O. This require remote update on the FPGA.

    Thanks SooY. We cannot change our board connections so cannot use another digital IO. Do you have more reference on "you change the FPGA image when you want to have that pin as digital I/O"? We already have the remote remote update configured. Thanks and your help is much appreciated.
