TCXWriter is a lightweight library designed for Arduino and ESP32 projects that involves recording and storing GPS and heart rate data in the Training Center XML (TCX) file format. This library simplifies creating TCX files by providing intuitive functions to initialize, add trackpoints, and finalize TCX files. It seamlessly integrates with Arduino's SD library, making it compatible with various platforms. The TCXWriter framework enables developers to effortlessly log location and health data during activities such as cycling or running, facilitating easy analysis and visualization of performance metrics. Primarily, it was designed to support the development of lightweight sports trackers.

TCXWriter should, in theory, work on all Arduino devices, but those specific devices have been reported as working:

• Arduino Nano

Reading/parsing TCX files can be quickly done using the following software packages or frameworks:

• sport-activities-features
• tcxreader
