 NOTICE: THIS IS AN ARCHIVAL COPY OF THIS COURSE. For the latest version, please visit our interactive classroom. When the program is compiled correctly, you can use "make program" to send it to the APP-IV. If any files are out of date, the makefile will rebuild them, so you could have used it first, although no programming will occur if there were errors in the build process. The makefile will prompt you to place the jumper cap on the APP-IV and press the reset button onboard. When you press Enter, the programming software will download your program to the board. Here's what the screen looks like: Place jumper cap on and press Reset NOTE: If you have a terminal program active, disconnect it Then press enter uisp -dprog=avr910 -dpart=auto -dserial=/dev/com1 --erase --upload if=tutor.hex --verify -v Programmer Information: Software Version: 2.3, Hardware Version: 1.0 Address Auto Increment Optimization Enabled Trying with: ATmega8 BOOT Atmel AVR ATmega8 is found.

You'll want to start up a terminal program (for example, Hyperterminal) and set it up for 19200 baud, 8 bits, no parity, 1 stop bit, and no hardware handshaking. When the terminal program is connected, you can press the reset button on the APP-IV to see the results. If you don't have local echo turned on in your terminal program, you won't be able to see what you are typing (which is not a big deal). Be sure to close or disconnect the terminal program before trying to program again. This program is fairly simple, but for a real program, you might want to debug the program or optimize it to some degree.
