Development of a microcontroller program for the pulse oximeter registrar Seeed Studio XIAO nRF54L15 Sense and MAX30102
Hello. It is necessary to develop a microcontroller program for the pulse registrator Seeed Studio XIAO nRF54L15 Sense and MAX30102. Data transmission (from LEDs at 250 Hz, gyroscope, accelerometer at 100 Hz) needs to be organized in real-time. The packet size will need to be determined experimentally. It is also necessary to send battery status data and device information to the mobile application (we are developing it). The data transmission modes from the pulse registrator will need to be changed. For example, continuously, every 10 seconds each minute, every 5 minutes. We are developing a telediagnostic platform where various devices are already working. It is necessary to develop a schematic diagram, an image of the connection of Seeed Studio XIAO nRF54L15 Sense + MAX30102 and the battery.
Software: library and headers for MAX30102. Code for Seeed Studio XIAO nRF54L15 Sense, debugging the program, adjusting the operating parameters of MAX30102, profiling consumption. The application should allow controlling the polling duration, duty cycle, LED brightness….., to find the optimal operating mode.
