PROFILE
Joonas Ihonen
Over a two-month period, this developer focused on enabling sensor data acquisition for i.MX9-based embedded systems by implementing internal SAR ADC support across the tiiuae/nuttx, tiiuae/px4-firmware, and apache/nuttx repositories. Using C and C++, they developed and integrated ADC drivers that handled initialization, calibration, power sequencing, and one-shot data reads, ensuring accurate 12-bit data extraction from hardware channels. Their work included aligning APIs and submodules across repositories for consistent behavior, establishing a robust foundation for sensor data pipelines. The technical approach demonstrated expertise in embedded systems, driver development, and hardware interfacing, with an emphasis on reliability and maintainability.

Apr 1, 2026April 2026 monthly summary focusing on key accomplishments in tiiuae/nuttx and tiiuae/px4-firmware. Delivered cross-repo i.MX9 internal SAR ADC support enabling single-conversion data acquisition on i.MX9-based devices. Nuttx: internal SAR ADC support with configuration, new source files, initialization and read functions for ADC channels (commit 6b1f3714272766f9e22cc139efb189cfd39cba0f). PX4 firmware: IMX9 internal SAR ADC functionality including initialization, deinitialization, and sampling methods with related submodule updates (commit 3b718861fd7751fbddcade81d08bcdf0b6dcd331). Impact: unlocks sensor data acquisition on i.MX9 platforms, enables richer applications and faster go-to-market for embedded products. Skills/Technologies demonstrated: embedded C, hardware peripheral programming, RTOS (NuttX), ADC subsystems, submodule management, cross-repo collaboration.
