GPIO and Basic Peripherals

GPIO and Basic Peripherals · TESA Firmware SDK for Edge AI course

Objectives

Talk to hardware through the Driver layer: LEDs, buttons, UART, I²C, PWM and ADC, on the project you can build/flash from Module 2, then combine them into a small circuit.

Lessons

#	Lesson	Content
1	GPIO and peripherals through the Driver API	Controlling LEDs, buttons, UART, I²C, PWM and ADC through the Driver layer, and knowing where SPI and timers sit in the stack
2	Lab: GPIO and peripherals on real hardware	Hands-on block by block: LED + button, UART logging, then choosing at least one of PWM / ADC / I²C, before combining them into a mini circuit

Approximate time per the original: about 3 hours (lessons) + a 2.5–3 hour lab.

Accompanying sheets and templates (in the resources/ folder of lesson 1):

• peripheral-api-map.md

The C code in this module uses the API of the TESAIoT Bitstream firmware, which is not yet open source. Read the note at the top of the lesson before you start.

Checkpoint

Before moving to the next module, check that you can do the following:

• A button toggles an LED on the real board
• There is a log over UART you can read on a terminal
• At least one of PWM, ADC or I²C works, with the real function names you called noted in the sheet
