类型定义说明

TAL_UART_IRQ_CB

typedef VOID_T(* TAL_UART_IRQ_CB) (TUYA_UART_NUM_E port_id, VOID_T *buff, UINT16_T len)

uart irq callback

参数

[in]	port_id	uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)
[out]	buff	data receive buff
[in]	len	receive length

返回

none

函数说明

tal_uart_deinit()

OPERATE_RET tal_uart_deinit

(

TUYA_UART_NUM_E

port_id

)

deinit uart

参数

[in]

port_id

uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)

注解

This API is used to deinit uart.

返回

the uart deinit result, 0, deinit success, other deinit error

tal_uart_init()

OPERATE_RET tal_uart_init	(	TUYA_UART_NUM_E	port_id,
		TAL_UART_CFG_T *	cfg
	)

init uart

参数

[in]	port_id	uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)
[in]	cfg	uart configure

注解

This API is used to init uart.

返回

the uart init result, 0, init success, other init error

tal_uart_read()

INT_T tal_uart_read	(	TUYA_UART_NUM_E	port_id,
		UINT8_T *	data,
		UINT32_T	len
	)

read data from uart

参数

[in]	port_id	uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)
[in]	data	read data buffer
[in]	len	the read size

注解

This API is used to read data from uart.

返回

>=0, the read size; < 0, read error

tal_uart_rx_reg_irq_cb()

VOID_T tal_uart_rx_reg_irq_cb	(	TUYA_UART_NUM_E	port_id,
		TAL_UART_IRQ_CB	rx_cb
	)

enable uart rx interrupt and register interrupt callback func

参数

[in]	port_id	uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)
[in]	rx_cb	receive interrupt callback

返回

none

tal_uart_write()

INT_T tal_uart_write	(	TUYA_UART_NUM_E	port_id,
		CONST UINT8_T *	data,
		UINT32_T	len
	)

send data by uart

参数

[in]	port_id	uart port id, id index starts from 0 in linux platform, high 16 bits aslo means uart type, it's value must be one of the TUYA_UART_TYPE_E type the low 16bit - means uart port id you can input like this TUYA_UART_PORT_ID(TUYA_UART_SYS, 2)
[in]	data	send data buffer
[in]	len	the send size

注解

This API is used to send data by uart.

返回

>=0, the write size; < 0, write error
