simavr - a lean and mean Atmel AVR simulator for linux

Origianl repo: https://github.com/buserror/simavr

This repo created for debugging of GRBL project under Windows, using real CNC host applications on the virtual CNC machine.

Steps to create debugging environment:

1. prepare MinGW environment (install to F:\MinGW)
2. prepare AVR toolchain (install to F:\AVR\bin\Atmel_Toolchain)
3. install VScode
4. install Free Virtual Serial Ports

• add virtual COM port bridge, for example COM2-COM3

5. checkout this repository
6. open repository folder in the VScode
7. build the project
8. start debugging:

• start debugging of simulator app: a. select debugger configuration (gdb) Launch b. start debugging
• start debugging of GRBL: a. select debugger configuration Attach to gdbserver b. launch in the terminal grbl_cnc.exe -g \\.\COM2 c. start debugging

9. Launch your preferred CNC host app (g-code sender)

• select COM3 port (where connected grbl_cnc.exe)

10. continue debugging as usual

Attention! By default:

• working disk is F:
• path to MinGW: F:\MinGW
• path to AVR toolchain: F:\AVR\bin\Atmel_Toolchain
• path to repository: F:\AVR\src\simavr
