I.MX23 LRADC

[sujathap_m_]

Hello,

I am using i.MX233 EVK from FSL ,and the Linux 2.6.31.

I am using LRADC channel 1 to read potentiometer voltage. I am able to read LRADC channel 1,but which is giving constant values(529/530/531). Is this channel internally configured to read some other voltages? If it is so how to deconfigure that ?

Regards,

Sujatha

Sujatha,

LRADC1 channel is connected to external MIC for MIC bias in EVK board. Why do you want to read external voltage value at this channel?

Do you want to measure external voltage from LRADC1 channel without MIC function, right?

Best regards,

Paul
