Am working on a project that needs a high speed ( 57600 and above ) serial communication
My development environment is the Atmel Studion 6.2 (with VisualMicro plugin), AVRISP MKII Programmer,
and Atmel Atmega328 MC with a 16MHz external crystal.
From the Device Programmer I set the SUT_CKSEL Fuse to EXTXOSC_8MHZ_XX_16KCK_14CK_65MS ( 8Mhz was the highest I could find )
the visualmicro enables me to use my Arduino code development background
Am trying to communicate with a ESP8266 Wifi module via serial, when I try at anything above 19200 bps it fails,
using an FTDI Cable I could communicate with the wifi module at 115200 bps so I know it not the modules limitation
I know Arduino boards with Atmega328 can do serial at 115200 bps so why can't I do same?
Am I missing something or is there any other setting I need to set on the Device programmer
What is the highest reliable baud rate I can do with 3.3v powered Atmega328 running at 16MHz Ext Crystal?
Thanks for any insight
