AD conversion ﴾ARPI600 on‐board chip TLC1543﴿
Configuring Pin A0 to Pin AD
1. Please make sure you have installed relative libraries ﴾refer to the Section 2.2: Installing
relative libraries﴿.
2. Set the jumpers to select reference voltage:
Connect REF to 5V, which means the AD conversion reference voltage is 5V
﴾connecting to 5V is a default setting﴿.
Connect REF to 3V3, which means the AD conversion reference voltage is 3.3V.
