i2c_slave_write() function
Write buffer to hardware fifo. If write length is larger than hardware fifo, then restore in software buffer.
Syntax
esp_err_t i2c_slave_write(i2c_slave_dev_handle_t i2c_slave,
const uint8_t *data,
uint32_t len,
uint32_t *write_len,
int timeout_ms);
Implemented in ![]()
i2c_slave_v2.c:343
Return value
- ESP_OK: I2C slave write success. - ESP_ERR_INVALID_ARG: I2C slave write parameter invalid. - ESP_ERR_TIMEOUT: Operation timeout(larger than xfer_timeout_ms) because the device is busy or hardware crash.

Description
Initialize an I2C slave device
Set I2C slave event callbacks for I2C slave channel.
Deinitialize the I2C slave device
Read bytes from I2C internal buffer. Start a job to receive I2C data.
Write bytes to internal ringbuffer of the I2C slave data. When the TX fifo empty, the ISR will fill the hardware FIFO with the internal ringbuffer's data.
