Week_5: Embedded Programming

Programing the board to do something was this week’s assignment.
I used the ESP32 Wroom board I made in week4. I downloaded the esp32 library from GitHub and uploaded it to the Arduino IDE using board manager.




Somehow, the board didn’t let me program.
Checked all traces with a multimeter, but I couldn’t find the problem; it seems like the current flow is just fine.





After a few hundred hours, I realized that I had messed up designing the board.
The RX and TX trace was switched from the esp32 Wroom chip to the programming pin.>
Using the jumper wire, I fixed the problem and ran the existing example code provided by Arduino, Wifi Scan.




* I fell badly, and my delicate board got broken. No one could figure out what was wrong... So I milled Neil's example ESP32 board and took a video of it working. SAD...

* Also tried ESP32-CAM for fun. Found an easy tutorial on randomtutorial.com.
