SPI Bus BMP280 Pressure Sensor

Having added a Serial Peripheral Interface (SPI) driver, it was tested with a widely available and inexpensive board module that uses the Bosch BMP280 barometric pressure / temperature sensor. Here is a link for a typical example, but there are many alternative sources: Amazon link. You may also need some suitable cabling, such as female-to-female ribbon cable (example here) and a soldering iron to connect the pin header.

If this sensor is connected, the uboot-driver-example test application will use it (see Using the U-Boot Driver Library).

The wiring connections using the MaaXBoard's 40-pin GPIO connector are as follows, accompanied by some reference photographs.
