The ATTiny 85 (or making your own microcontroller)
For this first assignment we started by soldering a jig and programing the ATTiny 85.
We started in class by burning the bootloader and getting correct clock settings on the ATtiny85, then running a simple blink code to see that all is working correctly.
finishing the soldering job I must say it all went well until one mistake made it all go south. After a pretty nice soldering job (if I might say so myself) I realized I connected the socket the wrong way and got a painful lesson in desoldering, It is not as simple as it seems. Ended up doing the whole thing over just to get a nice clean programing jig.This is the result all ready to push code and see if it works..
Moving on to the next step I removed the ATTiny on to a breadboard and tried to light up the LED following the steps as described in the website. Unfortunately nothing happened. so I thought maybe it would be beneficial to go through the process of bootloading the jig again, I think I did something wrong because that didn’t work either!!
I think there are still concepts in electronics I find hard to truly comprehend and then when something goes wrong I don’t know how to fix it.. so I didn’t even get to the point of creating my own circuit.
Update!! After going over the jig and circuit with my prof. we identified the problems:
- My resistor was in the wrong place
- We suspected that the ATTiny might be faulty
After fixing those issues I am glad to report that I was able to upload the “blink” example code and assemble the circuit with the ATTiny of the jig.
Now I can go ahead and upload my own code.
