Major Problems with Software (and hardware?) ADC Delta Sigma Reading Way Off
I did some work on a circuit board to convert a load cell output (0-15mV) into a force that is transmitted to a PC. The software worked fine, and then I lost it, and recreated it. Now nothing seems to work. There are a few things that stick out:
-The load ADC does not read accurately at all, and bounces around a lot. If I set it up as it is in the file, it reads off when given a 10mV signal. It reads off about 40%, and bounces around. If I set it up as a level shift buffer in order to maximize the resolution it actually reads negative.
-There is an error by my first interrupt handler that I do not understand.
-A lot of the 'smart completion' selections are missing entirely. I try to type 'UART_PutString' and it never appears under the smart completion options.
Any ideas are greatly appreciated.
