link macro between API function calls and bus read function
If the bus_read parameter calling order is like: reg_addr, reg_data, wr_len it would be as it is here.
If the parameters are differently ordered or your communication function like I2C need to know the device address, you can change this macro accordingly.
BMP280_BUS_READ_FUNC(dev_addr, reg_addr, reg_data, wr_len)\ bus_read(dev_addr, reg_addr, reg_data, wr_len)
This macro lets all API functions call YOUR communication routine in a way that equals your definition in the refer BMP280_WR_FUNC_PTR definition.
| #define BMP280_BUS_READ_FUNC | ( | device_addr, | |
| register_addr, | |||
| register_data, | |||
| rd_len | |||
| ) |
| #define BMP280_BUS_WR_PARAM_TYPES |
| #define BMP280_BUS_WR_RETURN_TYPE s8 |
Define the calling convention of YOUR bus communication routine.
If your communication function looks like this:
write_my_bus_xy(u8 device_addr, u8 register_addr, u8 * data, u8 length);
The BMP280_WR_FUNC_PTR would equal:
BMP280_WR_FUNC_PTR s8 (* bus_write)(u8, u8, u8 *, u8)
Parameters can be mixed as needed refer to the refer BMP280_BUS_WRITE_FUNC macro.

The following definition uses for define the data types.
For the Linux platform support Please use the types.h for your data types definitions
