PCB exposure |One of more advanced PCB manufacturing methods is exposing laminate copper boards covered by photo resistive layer through mask. Hi, hope you read this! When I click deploy I get this: avrdude.exe: AVR device initialized and ready to accept instructions Reading # 100% 0.01s avrdude.exe: Device signature = 0x000000 (retrying) Reading # 100% 0.01s avrdude.exe: Device signature = 0xffffff (retrying) Reading # 100% 0.01s avrdude.exe: Device signature = 0x000000 avrdude.Ultraviolet light source UV- 8. I believe that in rare cases, you can get a processor that has a corrupted signature, in which case, you can still program it by using the -F - but it should only ever be used in a one-off situation.
If, however, you have put a -F among your parameters, it ignores the result of the test - though I think it still logs something to the screen. That way, it avoids destroying chips if you have accidentally put in the wrong type. When AVRdude looks at the target chip, it reads its signature, which is a 3-byte number, and compares it with what it should be according to the chip type in the parameters. In order to check, go to Device ManagerCOM&LPT Ports and you should see Arduino listed. The COM port you are using your Arduino Uno on. In this line there are three main things to be altered. The Command field is to be filled with the location avrdude in your machine, in my case: C: Program Files (x86) Arduino hardware tools avr bin avrdude.exe As to the Arguments field, fill in with the following line: -U lfuse:w:0xe6:m -U hfuse:w:0xd9:m -e -v -patmega328p -carduino -PCOM2 -b19200 -D -Uflash:w:'$(ProjectDir)Debug $(ItemFileName).hex':i -C'C: Program Files (x86) Arduino hardware tools avr etc nf' Those are the firmware deployment arguments or information to be interpreted by AVRDUDE and converted into write actions. Go to ToolsExternal Tools Fill in the fields as the picture shows. Basically, Atmel Studio leaves this open enough to customization, that with the press of a button, you can perform a full command line program call and deploy your firmware to the target microcontroller.
