Part Number:TMS320F2808
Hi,
I'm going through details of Offset Error Correction procedure outlined in TMS320x280x DSP Analog-to-Digital Converter (ADC) Reference Guide, SPRU716D, section 1.9, Offset Error Correction, p.31. This procedure recommends to begin correction process with having about 20 conversions of ADCLO reference. I couldn't find any information in this guide as to how to configure ADC for such a conversion so my question is as follows.
Q: Does 2808 device have any internal resources that would assist in temporarily connecting ADCLO reference to the input of the ADC channel for purposes of this conversion or should I simply treat ADCLO as an external signal and permanently sacrifice one of the available ADC input pins to connect ADCLO reference to the ADC module externally?
Since some other TI devices provide internal dedicated resources for the said purpose, I expected 2808 to include similar functionality as well.
Please clarify this moment for me.
Regards, Michael
