SPI flash boot problem
Posted: Wed Mar 29, 2023 11:57 am
Hi everyone, I am using ESP32-WROOM-32 to create a healthcare device for a school project. I am working with MAX30102, and I use library "SparkFun MAX3010x Pulse and Proximity Sensor Library" and run example code from the library. Only one example code for measuring SPO2 "Example8_SPO2.ino" is having this problem while the rest of the other example codes work perfectly. Here is what I got from Serial monitor when I run "Example8_SPO2.ino":
This is very weird and strange for me. I have erased the flash several time, unconnected esp32 with MAX30102, and checked for current and power using a multimeter, but everything is fine. How can I solve this problem?
