neryggc Posted April 27, 2015 Share Posted April 27, 2015 Hi, i got a doubt. I want to use a PmodAD2 for ADC conversions. It uses I2C for comunication And i already bought the Pmod, but now i would like to know if it comes with the pull-up resistors needed on itself or i have to add them externally? I guess i just need to plug the pmod to my Nexys and run it but i want to make sure about it. I hope you understand, My english is not good. Thank you Link to comment Share on other sites More sharing options...
JColvin Posted April 27, 2015 Share Posted April 27, 2015 Hi neryggc, According to the schematics of the PmodAD2, there are no pull-up resistors on the Pmod. However, with a FPGA you may be able to program its own pull-up resistors on the IO pins. Unfortunately, I don't know enough about FPGAs to know how you might program that. You can always add the pull-up resistors externally though. Thanks, JColvin Link to comment Share on other sites More sharing options...
neryggc Posted May 20, 2015 Author Share Posted May 20, 2015 The PmodAD2 doesn't have the pull-up resistors needed on itself. Link to comment Share on other sites More sharing options...

Hi,
i got a doubt.
I want to use a PmodAD2 for ADC conversions. It uses I2C for comunication

I guess i just need to plug the pmod to my Nexys and run it but i want to make sure about it.
I hope you understand, My english is not good.
