Hello everyone,
I built the project with exact hardware and software.
I burnt the main.hex from the orginal file with no modification.
Here are the behaviors I found.
1. When the start button pressed, first letter sent missing, after that, the following letters are correct.
2. The maximum value of the ADC is 2557 in my case of the USB vcc is 5.07 volts.
3. The ADC values go up gradually by itself even the input source is a stable voltage source.
4. When the stop is a long stop, re-press the start button. It is not sending data to the host. I have to do a reset. i.e. unplug usb and re-plug usb.
Any one can help to make it better is really appreciasted.
Thanks,
Whazup
