rcsim opened a new pull request, #16146:
URL: https://github.com/apache/nuttx/pull/16146
## Summary
This commit adds support for the BMP180 sensor on the STM32F401RC-RS485
board and updates the board documentation accordingly. It also enables the
BMP180 UORB driver in the STM32 common logic.
## Impact
* Is new feature added? Is existing feature changed? Yes, Added BMP180
support to STM32F401RC-RS485 and
BMP180 UORB driver in the STM32 common logic.
* Impact on user (will user need to adapt to change)? Yes, users will be
able to user BMP180 on STM32F401RC-RS485
* and BMP180 UORB on other STM32 boards.
* Impact on build (will build process change)? No
* Impact on hardware (will arch(s) / board(s) / driver(s) change)? Yes,
STM32F401RC-RS485 and STM32 Common.
* Impact on documentation (is update required / provided)? Yes,
STM32F401RC-RS485 was updated.
* Impact on security (any sort of implications)? No.
* Impact on compatibility (backward/forward/interoperability)? No
## Testing
The test was done using two configurations:
Regular Driver:
CONFIG_ARCH_BOARD_COMMON=y
CONFIG_STM32_I2C1=y
CONFIG_EXAMPLES_BMP180=y
CONFIG_SENSORS=y
CONFIG_SENSORS_BMP180=y
```
NuttShell (NSH) NuttX-12.8.0
nsh> bmp180
