TESAIoT Firmware Stack: C Firmware on the TESAIoT Dev Kit

The core TESA Qualification Program course for developers. You write C firmware for the TESAIoT Dev Kit (the PSoC Edge AI Kit SoM on the QWA309 base board) with ModusToolbox and TESA’s master template. Every lesson is tied to a real example on the TESAIoT Developer Hub (github.com/tesaiot/developer-hub), pinned to an exact commit.
Level L3 Independent
Time about 25 hours
Board TESAIoT Dev Kit (lesson 5.3 uses the Eva Kit, as its example’s BSP does)
Tools ModusToolbox 3.6 or later, git, a USB-C cable for KitProg3
You should know C at level L2 (variables, functions, basic pointers and structs)

Outcomes

Section titled “Outcomes”
  1. Build and flash C firmware to the TESAIoT Dev Kit with ModusToolbox and the master template on your own.
  2. Build a touch-screen HMI with LVGL, from a label to a Wi-Fi manager with a state machine and NVM profiles.
  3. Read every on-board sensor and the PDM microphone and combine them into a smooth dashboard.
  4. Use GPIO, ADC, I2C, CAN, UART, SPI and PWM on the QWA309 base board and confirm signals with an instrument.
  5. Send data to the TESAIoT Platform with Server-TLS and mTLS, and explain the role of OPTIGA™ Trust M.

Modules

Section titled “Modules”
Module Lessons Examples from
1 · Getting started with the TESAIoT Dev Kit 1 master template (tesaiot_dev_kit_master)
2 · HMI Menu & Setting with LVGL 7 Episodes series 1 (hmi_ep01–hmi_ep07)
3 · Sensors and audio on the TESAIoT Dev Kit 7 Episodes series 2 (int_ep01–int_ep07)
4 · Hardware on the QWA309 base board 5 practice codes prac_qwa309_*
5 · Connecting to the TESAIoT Platform securely 4 embedded-devices and security examples

The lesson pages are in Thai for now; the code and every example README they link to are on GitHub.

Where the code lives

Section titled “Where the code lives”

All code stays in the Developer Hub and is linked at pinned commits, never copied, so there is one source. The episodes, the practice codes and the examples on main are Apache-2.0; the master template and the OPTIGA client are under Infineon/Cypress EULAs.
