i have done it all the problem is that i dont really know where to begin the coding or start programming. in other modules we can do very basic example to get started like led blinking etc. can you tell me where did you learn arm?
yes it is dear
honey i just need to use adc and uart. i will try my best to do it in 3 weeks. and yes please send me your codes.
