I thought I could acquire a clone from the BME280 and got a GY-BME/P280.
Already the name of the sensor made me wonder: did I have an E or a P in my hand now? Which Libary was the right one: I tried different libaries, but without success.
In order to exclude wiring problems, I concentrated on I2C: without success.
I get no values in the serial output. Tested with 0xD0, 0x76 and 0x77. When I2C scanned no address, I switched to SPI.
With hardware SPI I had tried the following wiring, without success:
#define BMP_SCK A3 // > SCL This is the SPI Clock pin, its an input to the chip #define BMP_MISO A4 // > SDO this is the Serial Data Out / Master In Slave Out pin (MISO), for data sent from the Sensor to your processor #define BMP_MOSI A5 // > SDA this is the Serial Data In / Master Out Slave In pin (MOSI), for data sent from your processor to the Sensor #define BMP_CS A2 // > CSB this is the Chip Select pin, drop it low to start an SPI transaction. Its an input to the chip
It ended in breathing Photon white.
Can you breathe life into the sensor?
