FABACADEMY
Electronics Production
Welcome to my week 5
Am thinking of making the ISP so i followed the Brian's Broad.
Electronic Production:

This test was performed to check the capability of the machine In this mill job test tracks from 1 Mils to 20 Mils were made and from the image it may be concluded that the machine was able to print 1 Mils also, but the track quality is not upto the mark, It was observed that the tracks above 12 Mils were perfect

.RML File
For making .rml file I used Fabmodules.org
Here is the step by step guide to generate the .rml file
Step 1: Open Fabmodules.org and select the input format as Image(.png)

Step 2: Open the file (.png) and select the output as .rml

Step3: Now select the process as PCB Traces (1/64) as we are going to mill the traces for outline we'll use PCB Outline (1/32).

Step4: Now Select the machine which is in our case SRM 20

Step5: Now set the parameters as : and then click on save to download the file

Step6: Now after downloading the RML file, it time to mill out the board. Open V panel for SRM 20

Step7: Now go to CUT button and select the downloaded RML File followed by clicking on Output
Precautions :





Download the firmware source code

If you installed correctly the red LED lights up.
Connect the programmer to the ISP header on your board. Run make flash. This will erase the target chip, and program its flash memory with the contents of the .hex file you built before.
Once you’ve succesfully programmed the flash memory, it’s time to set the configuration fuses. We’ll do this in stages: First, set the fuses that control where the microcontroller gets its clock source from. Run the make fuses command. This will set up all of the fuses except the one that disables the reset pin.
