Function Documentation

ftd2xx_i2c_init()

int ftd2xx_i2c_init	(	struct no_os_i2c_desc **	desc,
		const struct no_os_i2c_init_param *	param )

Initialize the I2C communication peripheral.

Parameters

desc	- The I2C descriptor.
param	- The structure that contains the I2C parameters.

Returns

0 in case of success, -1 otherwise.

ftd2xx_i2c_read()

int ftd2xx_i2c_read	(	struct no_os_i2c_desc *	desc,
		uint8_t *	data,
		uint8_t	bytes_number,
		uint8_t	stop_bit )

I2C read transaction as master.

Parameters

desc	- The I2C descriptor.
data	- The buffer where received data is to be stored.
bytes_number	- Number of bytes to receive.
stop_bit	- Specifis whether to end the transaction with a stop bit.

Returns

0 in case of success, -1 otherwise.

ftd2xx_i2c_remove()

int ftd2xx_i2c_remove

(

struct no_os_i2c_desc *

desc

)

Parameters

desc	- The I2C descriptor.

Returns

0 in case of success, -1 otherwise.

ftd2xx_i2c_write()

int ftd2xx_i2c_write	(	struct no_os_i2c_desc *	desc,
		uint8_t *	data,
		uint8_t	bytes_number,
		uint8_t	stop_bit )

I2C write transaction as master.

Parameters

desc	- The I2C descriptor.
data	- The buffer with the data to transmit.
bytes_number	- Number of bytes in the buffer.
stop_bit	- Specifis whether to end the transaction with a stop bit.

Returns

0 in case of success, -1 otherwise.
