USBaspLoader - Metaboard - UART
Posted: Thu Jul 15, 2010 7:19 pm
I am new to this forum and i want to say hello before i state my question 
I come from berlin so please take into account that my english skills arent that advanced. thank you.
The issue i want to deal with is to use the USBaspLoader to program several types of atmel uC like the metaboard. I searched the internet and this forum for an answer to the question whether it is possible to use RXD/TXD to communicate with an just programmed uC. I would like to use ATMega8 to flash the bootloader on and its hardware UART like i did it with an RS232 interface before. i built in a little switch because the pin 2 of the sub-d9 was used to program as well to communicate with the uC and i also had to deactivate DTR at my terminal program (developed on my own).
to sum up my question:
how to make the USBaspLoader recognize that the data i send will not be programming data? or in other words: should i better use a switch and a Tiny2313 with CDC to use the usb port to communicate with the just programmed uC? the disadvantage in this case would be that i need 2 uC.
I hope you can help me and that i stated my question correctly containing all relevant information, or give good advice, thank you
greetings, eKuaLL
