Make an in-circuit programmer by milling the PCB (program it, so that you can use it to program your board in Electronics Design week, and in other weeks)

I select the Valentin board to make this assignment; this board is use as a programmer. At the end of the page, you can find the link for more information.

Demonstrate correct workflows and identify areas for improvement if required

In the web page of fab module can modify the file to process in the machine. In the next image, you can see all configuration and steps to make the image process.

Frist select the format and the image
Second select output format
Third select drill
Next Setting point origin
Next setting for cutting or engraving
To finish generate calculation

Describe the process of milling, stuffing, de-bugging and programming

Before starting be sure you have the correct drill 1/64 (traces) or 1/32 (cut) and be sure that plaque fixed to the machine. Once secured. We begin the configuration go the machine starting with placing the starting point of the machine in "X" and "Y" (x=0, y=0) and setting z with the sensor that is connected because can damage the sensor, before to start cutting, verify all the parameters be correct and press "cut" to proceed.

PROGRAMMING

In order to program the board, you use a Mega Arduino which will be programmed as an ISP to select this library are chosen inside the library of examples as you can see in the image.

Download the following link in which we will find a software with which the file is loaded to the micro controller of the board.

Open the file MAKE FILE with NOTEPAD ++ and edit the file.


We installed the program CYGWIN with which we created a simulation window.
In the program, we enter until locating the folder in which the FRIMWARE was saved.
To be able to locate in the folder we enter CD CYGDRIVE and the next step is to locate us in the direction of the file Following is cleaned the files that are already generated with the command MAKE CLEAN Then the hexadecimal file is generated with the command. MAKE HEX Next, we compile the fuses. MAKE FUSE Finally, we programmed, we uploaded the Arduino file to the plate MAKE PROGRAM

FAILS

I had two small mistakes in developing the assignment.

The first in the milling process, where some tracks were joined as can be seen in the following image. To solve with a blade the affected areas are cut.

In addition, the second one found a damage on the microcontroller so it had to be replaced. In this way could be programmed without any problem.
