The 'msba2' common files have accumulated many empty files are files that
do nothing.
This makes reasoning about the boards needlessly difficult.
Trim down on `common/msba2/` so that it now only contains the setup for the
UART/bootloader based flashing.
This should eventuelly be moved to `makefiles/tools/`
- Removed cc110x driver
- Updated all makefiles
- Kept both board specific configurations and support for it in RIOT's
upper layers, so re-implementations don't need to start from zero
The MSB-A2 and the Avsextrem board once had support for using the USB
interface of the LPC2387. The code setting up the USB clock has been unused
for ages and is now defunct, as the required value for `USBCLKDivValue` is no
longer present in RIOT's code base. This commits removes the defunct and unused
code.
Introduce and use a common/msba2/Makefile.features.
The boards were already using the common `Makefile.include` and
`Makefile.dep`.
This makes 'include $(RIOTCPU)/lpc2387/Makefile.features' be done in
the same module where 'CPU' is defined.
Preparation for moving 'CPU' definition to Makefile.features.
The file always exist so no need to do '-include'.
Replaced using:
sed -i 's|-\(include $(RIOTCPU)/.*/Makefile.features\)|\1|' \
$(git grep -l '$(RIOTCPU)/.*/Makefile.features' boards)
- Use RIOT's GPIO interface to access the sensor to increase portability
- Changed API to allow more than one sensor per board
- Added `sht1x_params.h` that specifies how the sensors is connected - each
board can overwrite default settings by #defining SHT1X_PARAM_CLK and
SHT1X_PARAM_DATA
- Changed arithmetic to use integer calculations only instead of floating point
arithmetic
- Added support for checking the CRC sum
- Allow optional skipping of the CRC check to speed up measuring
- Added support for advanced features like reducing the resolution and skipping
calibration to speed up measuring
- Allow specifying the supply voltage of sensor which heavily influences the
temperature result (and use that information to calculate the correct
temperature)
- Reset sensor on initialization to bring it in a well known state
- Support for the obscure heater feature. (Can be useful to check the
temperature sensor?)
- Updated old SHT11 shell commands to the new driver interface, thus allowing
more than one SHT10/11/15 sensor to be used
- Added new shell command to allow full configuration of all attached SHT1x
sensors
- Removed old command for setting the SHT11 temperature offset, as this feature
is implemented in the new configuration command
- Replaced magic numbers in the CC110X configuration of the MSBA2
with SPI_DEV(x) and GPIO_PIN(x, y) macros
- Adjusted implementation of `cc110x_params.h` to match the code of `at86rf2xx`
- Made MSBA2's CC110X parameters the default configuration
