running led program from port0.0 to port0.7 then back and continous I have try to make a project like running led from PORTA.0 to PORTA.7 but my problem is in the branch looping.In assembly 89c51 i can program running led like this: I have read a getting started document etc. So, i want to search online tutorial so i can learn to learning programing language. I didn't found any tutorial book to programming AVR using C language in my country.
In pascal language i understand to do some branch looping using while.do, if then else, for.do,etc,but using this C language i'm difficult to search similiary mnemonic which same with pascal language. Actually my basic in programming is in pascal, and i very newbie in C language. Your schematic very help me to learn programming AVR8535. The pony prog is a good and simple ISP programmer, but I would use a 6-pin header instead of a 10-pin header. Start reading a C book an you will soon get the idea. You can easyli make running leds without intterupt or any assembly commands. Start with the simple, and learn how to use the different loop types before you start using interrups or any assembly. I don't think you should start using interrupts or assembly commands yet. You use loops instead and function calls. You don't jump in C language like you do in assambly. It doesn't matter if the book is for AVR or not, the commands are the same, only some special port commands like PINA etc. You can find a lo of C books here at EDAboard. Then you will soon learn how to use for, if while etc. I think you should download a get a C book and start reading it.
Does anyone have a link or document how to learn assembling in c using codevision? I want to know how using a procedure,if(cjne or djnz),looping,while, for, etc. The doc 2500 from atmel only has a few information about how to assembly in c program using codevision avr. Thx to MR.ME i have to try to build some programs using ATmega8535, i have simulated that program using avr studio 4 and its working(i try to make programs which contain interrup 0).But i still confused how to jump to another label and how to using looping,if,while,in c language(in 8051 like cjne or djnz).Actually i still use a little assembly language in c program etc "SEI",it is true?Do anybody have a simple program to making the led running from PORTA.0 to PORTA.7 and then back and continous using ATMega8535 with c language using codevisionAVR 8Oĭoes anyone have and minimum system schematic or PCB layout for AVR8535,so i can simulated in hardware using led, and what isp cable should i use stk 200(like in ponny prog )?can i have the schematic for the cable which can working well?
