Hi list,
Sorry if this question has been asked.
I am wondering why in the I2C interface functions read and write, there is no
field for register address.
async command error_t read(i2c_flags_t flags, uint16_t addr, uint8_t length, u
int8_t* data);
async command error_t write(i2c_flags_t flags, uint16_t addr, uint8_t length,
uint8_t* data);
I guess the addr field is for device address, isn't it?
For reading data from a register, my function calls like:
call I2CPacket.write(I2C_START | I2C_STOP, deviceAddress, 1, registerAddr)
if sucessful,
call I2CPacket.read(I2C_START | I2C_STOP, deviceAddress, NumberOfBytes2Read
+ 1, &readData);
By using the above method, seemingly I am able to read values through I2C.
How about write? Anyone can shed some light on this issue.
Thx.
