13. Networking and Communications¶
13.7 Other projects-2 (serial bus) (as group assignment)¶
As my own project wasn’t completed, I made ATtiny412 serial bus demo boards by Adrian Torres as a supplementary lesson.

I programmed Arduino UNO with jtag2updi by Spence Konde and Arduino UNO became the writer for ATtiny412.


It was quite straight forward and the boards worked well!
13.8 Other projects-3 (SD-card) (as group assignment)¶
I had developed my own SD card shield for Arduino UNO as a part of Week 11 assignment.
The board connects Sunhayato CK-35 SD-card adapter with Arduino UNO.

The board design:

Step file:
SDshield.step
STL file:
SDshield.stl
The board connects with Arduino UNO using SPI interface. Pin assigns are belows:
| SD card shield | Arduino pin |
| CS | 9 |
| MOSI | 11 |
| MISO | 12 |
| CLK | 13 |
| 3V3 | 3V3 |
| GND | GND |
