Part Number:TMS320F280049
Hello everyone,
I am testing a self designed board with the F280049 and dont see any voltages appearing from VREFHI to VREFLO. The function I use to switch to the internal reference is taken from the C2000 ware.
ADC_setVREF(ADCA_BASE, ADC_REFERENCE_INTERNAL, ADC_REFERENCE_3_3V);
Two mistakes happen during the design and I dont know if this might have killed the internal reference. At first I forgot to connect the VREFLO to VSS and I also forgot to add a external capacitor to the pins. Both is now done after the chip has been powered up several times. I would be thankful for any advice so I can move on with the testing.
Regards,
Martin
