Hi!
I am struggling to run an atmega328p at 3.3V 8MHz and at the same time using an HC-06 Bluetooth module at 115200 bauds. The solution seems to be in this thread ( Pro mini 3.3v 8 Mhz 115200 baud issue - Interfacing w/ Software on the Computer - Arduino Forum )but I do not know how to implement it. Has somebody done it before? I need help on the baby steps on how to configure the micro at 8.3MHz running the last code provided in the thread by Uggima?
The code by Uggima sets up the OSCCAL, so that the internal oscillator works at 8.3MHz. Find this code here ( OSCCAL by ugg ).
Thanks in advance
