|

|
------
|
||||||
|
|
||||||
|
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.
