Embedded programming 2¶

Group assignment requirements¶

The group assignment for this week is the following:
- Browse through the datasheet for your microcontroller
- Compare the performance and development workflows for other architectures
- Document your work to the group work page and reflect on your individual page what you learned

Microcontroller datasheet¶

The microcontroller being used is the Xiao [insert name here] which is a micro-sized dev board based on a [NAME] microcontroller. To find the specs I am referring to the dev board’s datasheet here, and the microcontroller datasheet here. By going through the datasheet for both the microcontroller and XIAO dev board I learned a lot about the microcontroller including the following:

picture of the XIAO pin layout

The Xiao contains the following pins: [NUMBER] PWM pins [NUMBER] general digital pins [NUMBER] Analog pins [NUMBER] I2C interface

The XIAO dev board also contains the following components: [add # of buttons, LEDs, USB, and their functions]

As for the microcontroller itself, we found the following information from the datasheet:
