assignment

individual assignment: read the data sheet for your microcontroller program your board to do something extra credit: try other programming languages and development environments

group assignment: compare the performance and development workflows for other architectures

[1]This week I learned to program the previous boards I had created. From previous weeks I had made two boards, one with a D11 and one with a Tiny412. I had initially thought both would work similarly, but I quickly learned these two are very different. Most notably, D11 can talk Serial - USB while Tiny412 can’t. For this reason, I used a programmer with my ATTiny412. I used one I found on the Lab; however, the difficult part came when I realized I had to install libraries and boards in the Arduino IDE Boards Manager. I had to install megaTinyCore so that I could talk to the Tiny 412 using a programmer to convert Serial-USB to UPDI.

I was able to install two different programs, a Blink, and a Button On/Off program. One would control blink on and off automatically, and one would turn the LED on/off depending on the state of the button. Watching this work was extremely satisfying. Finally observing a working PCB. To program the D11 was more difficult. I tried it, however, I had forgotten I had previously programmed it on a previous week using OpenOCD. With help from Nathan, I realized it was locked by OpenOCD. I wanted my D11 to become a programmer so that I could program a future board, however, this wasn’t possible for the moment. Hopefully, in the next few days I will be able to fix this.

Considerations:
-Search and install the board libraries for the microprocessor you are using- Either megaTinyCore or ESP32.
-Figure out if you need to use a programmer, and if your board talks Serial or UPDI.
-As more variables are added to making, designing, programing boards it is harder and harder to troubleshoot what might be causing a problem. The difficulty in achieving a working board begins to compound.
-Check to see if the board you are using has known problems with your operating system (for example Windows or Mac). It is worth to try programing a board that is giving you problems using Linux.
