Dear All, Its been a while since I have posted here. I am working on the HC12C32 microcontroller on the Freescale EVB. I have a decent background of C and C++. I will be using the code warrior softwrae. But posting really simply doubts and queries is tedious and annoying to all on this forum to answer as well. Could you please suggest a good book on the subject for me to learn from?
