There's a little project I'm putting together for crowd funding that will run on an Atmel controller (atmega2560). I'm coding the "firmware" using Arduino IDE with the arduino Bootloader. I'm putting an on-board USB to Serial communications ic like the CH340 to allow my users to load firmware without having to buy the AVR ISP to do so. What I am wondering is - are there software solutions that load the program you coded in the arduino IDE without using the Arduino IDE.
I bought an arduino based CNC router machine two years ago and the manufacturer sent me some files, including the firmware loader. I just picked the serial port and it loaded the firmware onto the Arduino Mini without using the Arduino IDE. I'm looking for this sort of a deal
