My son has recently gotten into model rocketry and we’ve built and programed several Arduino based altimeters to record flight data from both BMP280 Barometric pressure sensors and GY-521 (MPU-6050) 3 axis gyroscope. All of our previous sketches have been run on the Arduino pro-mini and the data logged to a microSD card reader. However, with the much larger flash memory on the SMD21, it got me thinking that I could make a much smaller payload package by eliminating the microSD card reader. This iteration would also eliminate the GY-521 and just record altitude data.
Can anyone give advice/tip on how to write the data from the BMP280 directly to the flash memory on the SMD21. I haven’t found much documentation on the subject. I know that writing to the onboard can reduce it’s lifespan, but give the inexpensive nature of the board, that’s not really an issue.
Thanks in advance.
