Mistake !

Oh crap! Thank you. I have no idea how that got through.

Fixed.

Thanks again.

Hey, It's no problem. I recently purchased your book and I love it. But, I am having some problems in running the code. If it's okay can I share them with you? I am currently on the serial communication chapter.

Sure! Let me know what's up.

Hello, Thanks in advance ! In the the program listing serialloopback.c you have included some user defined libraries like the USART.h. I downloaded this from github and saved it in the folder containing the code and makefile but still the program did not run so I defined the specific functions in the program itself. And the compiler asked me to define the Baud rate and F_CPU and I don't know what F_CPU means. So as you can see its become pretty cumbersome and I have totally detracted from learning serial communication. I am also including the code I ended up with. If you could tell me what to do I would be grateful. best wishes Abhijeet Dutt Srivastava On Wed, Apr 12, 2017 at 1:30 PM, Elliot Williams <[email protected]> wrote:

F_CPU is defined in the Makefile. Are you using Atmel Studio? They have a location somewhere that you can enter user-defined parameters like this.

Project -> Toolchain -> AVR/GNU C Compiler -> Symbols
then add F_CPU=8000000 (or whatever)

Hey Eliot ! I had left working with your book ! I recently started again and am again stuck on the serialloopback code. Answering your previous mail - No I use programmer's notepad/Winavr. Please tell me where to get the pinDefines.h library and the USART.h library. I really love your book and I am learning a lot, I want to point out something on page 73 where its written "0xFF is 255 in hexadecimal" won't it be decimal? Thanks!

Hey Elliot I got the code running, soon after I wrote the above mail. However, I defined the functions you made in USART.h in the program itself. I use Winavr and Mfile please tell me how to compile a custom library along with the program- I just can't understand. Thanks so much. P.S Sorry If I bothered you with too many mails Abhijeet On Jan 24, 2018 7:38 PM, "Abhijeet D.Srivastava" <[email protected]> wrote:
