bmp280
------
Configures the NuttShell (nsh) over USB Serial (check usbserial configuration) and enables BMP280 Digital Pressure Sensor.
BMP280 has an I2C address that can be configure by SDO. Connecting SDO to GND results in slave
address 0x76, connection it to VDD results in slave address 0x77. This can be configured by enabling BMP280_I2C_ADDR_76 or BMP280_I2C_ADDR_77. This configuration uses I2C1 and slave address 0x77.
NSH commands::
NuttShell (NSH) NuttX-12.6.0-RC1
nsh> bmp280
Absolute pressure [hPa] = 911.400024
Temperature [C] = 26.110001
nsh> bmp280
Absolute pressure [hPa] = 932.650024
Temperature [C] = 24.490000
There is a known issue where every time the sensor is initialized, the first measurement is wrong, please check https://github.com/apache/nuttx/issues/12421 for the latest updates on this issue.
