If you have Arduino Debug Wire on your PC, this user manual should help you fix it. The silver used in the Arduino uses a new elegant proprietary Atmel method called “DebugWIRE”. JTAG uses a ten-pin connector and whatever I / O lines your circuit might need when debugging. DebugWIRE supposedly uses everyone – the dump string.
This describes how you can use an Arduino sketch made on an Arduino to control and debug another Arduino or a great AVR microcontroller like the ATTiny85. With some restrictions, you can use the Arduino workspace to split the code, view the code in one go, and change the current value of the registers. I / O ports and SRAM, as well as runtime code when dealing with a set of hardware breakpoints. And all your organization needs to do this is a RESET pin on the target device, a better> 10k ohm resistor for resetting Vcc, and an Arduino functional standard based on ATMega328 that acts like most of the control debugger. ForSince using a different Arduino as a target requires some changes to the circuitry of the target Arduino, this article will undoubtedly show you how to use a good ATTiny85 as a target. A longer term article will discuss the changes required to use the Arduino as a target for a phone. Although most of them have not been tested, the code I present is created to help you debug the following AVR devices:

1. Download Fortect and install it on your computer
2. Launch the program and click "Scan"
3. Click "Repair" to fix any issues that are found
S0060 =: 4321 Set the address value to 0x0060 taking into account 0x1234
S0060: 1234 Show modified content of address 0x0060

To run the code at full speed Enter “ RUN “, then click Submit . Unlike STEP , RUN the request activates target timers, so minute interrupts should be active while your system is running. You must use the RESET command before RUN you must use RUN the first time. This is what it looks like:
RESET: OK L0000 :: C00E rjmp 001E RUN: in progress
Alternatively, you can use all “ RUNxxxx "- command to start execution only at the address xxxx . For example, replacing the input RESET to set the PC (program counter) to 0x0000 Before entering the mileage, it is advisable to use " RUN0000 " and media send to get this response:
In both casesayah you implemented the small sample circuit correctly, you should now see an indicator at about 1. see / 2 glow, note that it quickly switches between ON and OFF. To stop the target and regain control with the debugger, enter "" size = "4"> BREAK Submit . You should receive a response like this:
L0112 :: 99B3 sbic 0x16,3
RESET: OK, enter RESET
EXECUTE: type Laufen EXECUTE
< / p>
BREAK: OK, BREAK entered
L010A: 9AC4 sbi 0x18.4 LED on
L010E: 98C4 cbi 0x18.4 Turn off LED
< code> L0112: 99B3 sbic 0x16,3 Check if the switch is pressed
L0114: CFFA, rjmp, 010A, temporary

For your information * This project is constantly evolving as I am still working on some details to figure them out. So if people have any problems using this standard, come back here for any upcoming updates in the future. Also, I want to get started so badly that what I have achieved in this area is now being made possible by the hard work of others like David S. W. Brown and RikusW. Someone’s undocumented work on decoding the debugWire log was invaluable
