hi dears. i am using atmega 32 with 8 MHZ crystal.i want to add keypad(16 keys) to my mega32.lcd is on porta and keypad is on portc. i tried to use codevision example but i didnt success.so please help me and please tell me source code with codevision. another problem is how can

Dear everybody, I wanted to use Differential ADC in atmega64,but it didn't work. I previously wrote similar codes for atmega16,So I changed them for atmega64(considering changes in ADC control bit positions).After all I came to the conclusion that something should be wrong with C

If low power in needed, all i/o pins need to be in valid high or low states. A floating input that has drifted to some intermediate level can cause the input buffer to draw more current than it would with a valid input. The simplest way to handle this, with an avr, is to set all

Thanks a lot for all sugestions, I will take somewhat like Roberts solution becouse its simple and low cost, but Im beginning with microcontrollers, so I will put to study and work hard for resolve the problem. In my country I cant buy a Tinys, but I will use atmega8. Thanks agai

Ditto on this! The overhead & cost of the Max31xx family was overtaken by the advantages of using another AVR. It was cheaper, could be put to sleep, could offload packet processing etc. More importantly it could do anything that we dreampt up at a later date. By using it as a co
