ATMege164P Bit setting help
Posted: Tue Nov 25, 2014 10:24 am
Hello, I have a AVR question i need help answering. NOTE: I AM NOT ASKING YOU TO GIVE ME THE ANSWER!! I am new to AVR Microcontrollers and would appreciate some help. I have included my answers.
An AVR is running from an 11.0592MHz clock. For serial transmission only, at 4800 Baud:
Which bit(s) in the UCSR0B need to be set?
What value needs to be loaded into the UBRR0 register? (Assume U2X0 = 0.)
----ATMega164p----
My Answer:
From the data sheet I would set bits: 1<<TXCIEn | 1<< TXEn | 1<<TXB8n
The values that need to be loaded into the UBRR0 register are:
UBRR0 = ( f / (16XBaud Rate)) -1
UBRR0 = 143
So values 143 needs to be loaded into the register
Can someone who is familiar with micro controllers confirm my answers as I am new to this. If they are wrong could you please correct me. much appreciated
Thanks
