Macro Definition Documentation

◆ BHY_I2C_SLAVE_ADDRESS

#define BHY_I2C_SLAVE_ADDRESS BHY_I2C_ADDR1

determines the I2C slave address of BHy The default I2C address of the BHy device is 0101000b (0x28).

◆ BHY_RESET_DELAY_MS

#define BHY_RESET_DELAY_MS UINT32_C(50)

the delay required to wait for BHY chip to reset

◆ I2C_ONCE_WRITE_MAX_COUNT

#define I2C_ONCE_WRITE_MAX_COUNT (8)

these two macros are defined for i2c read/write limitation of host

users must modify these two macros according to their own IIC hardware design

Function Documentation

◆ bhy_delay_msec()

void bhy_delay_msec ( uint32_t msec )

Initiates a delay of the length of the argument in milliseconds.

Parameters

[in] msec Delay length in terms of milliseconds
