I am using ADC to monitor the voltage of an analog input value to my BLE Pioneer Kit. I want to print the voltage value every 10 milliseconds. When I click the program button while in the main.c file under source code, the program doesn't seem to start right away. Only after a few minutes does "Voltage is 0 mV" start to print in Tera Term. After printing for about 30 seconds, symbols begin to appear in the Tera Term window. I've attached a text file of the serial data that prints to Tera Term. I've made sure that the baud rates match in tera term and in the ADC settings. The code that I use in main.c is below. Any idea what the problem might be?
