I had purchased a CT-ARM and was trying to learn how to use it. There are a few questions that I bumped into while using it, hopefully can get some guide/answer to it and also useful to other user.
1. Based on the datasheet of NUC131, the built in ADC was a 12-bit ADC. However, when I tried to use analogRead on one of the input, the max I could get is only 1023 when I connect it to the 5V, which is the max for a 10-bit ADC reading. For a 12-bit ADC, I am expecting to read something around 4095. So is the reading I get expected?
2. Based on the feature and specs, it is stated that there are 5+1 UART. May I know what is the 5+1 meant and which pins are the hardware UART pins?
Thanks
