CCS/TMS570LS0714: ADC pins random value problem.

Hello,

If everything is configured in a right way and you are reading the right pins ( especially those connected to GND ) the reading should not be random.

Set FIFO  size to be equal to the number of channels you are converting.

I don't think there is anything wrong with the sample code structure here.

I've reduced the number of FIFOs from 16 to 15.

Hello,

If you read unconnected ADC pins then reading will float (random). Those pins, connected to GND should not float. Are you using custom board or TI development board?

Hi,

The value increases when the pins give the correct voltage.

Card our own design and drawing as follows

Hello,

You can include channel ID in conversion result to ensure you are reading the correct channel.

I've noticed something like this: there's no problem reading a single adc pin, but when I activate the others, there's a problem.

what is the reason ? 

Can you send me more than one ADC pins reading code as an example?
