Function Documentation

int rc_i2c_send_bytes(int bus, size_t count, uint8_t *data)

Sends exactly user-defined data without prepending a register address.

Instead of automatically sending a device address before the data which is typical for reading/writing registers, the rc_i2c_send_bytes function send only the data given by the data argument. This is useful for more complicated IO such as uploading firmware to a device.

Parameters:

• bus – [in] The bus

• count – [in] Number of bytes to send

• data – [in] The data

Returns:

0 on success or -1 on failure
