hi everyone!
can anyone tell me about how can i programme an AVR through usart interface ?
i wrote a programe using bootloader memory ! and megaloader software as an interface!
then i want to send my programe to the COM port of my pc then load it on avr!
is there any C code example?
 

Tell us, what is your device.........

Atmel AVR Devices
Device Families

32-bit AVR UC3
8/16-bit AVR XMEGA
8-bit megaAVR
8-bit tinyAVR
 

i have decided to use CV-MegaLoader as an interface software !
can i connect a HM-TR module to PC Com port and send the hex code through rs232 and recive it on theother side?
and then load it on the chip?
 

You could e.g. use the bootloader code of the AVR109 application note, downloadable at atmel.com. It's using hex code, as most bootloaders.
