引腳號 | 名稱(chēng) | 功能 |
1~4 | P1_0~P1_3 | GPIO mode default, input or output (push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode. 默認GPIO模式,輸入或輸出(推挽結構),上電默認狀態(tài)由AD1和AD0決定??稍O置為L(cháng)ED模式。 |
5~8 | P0_0~P0_3 | GPIO mode default, input or output (open-drain (default) or push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode. 默認GPIO模式,輸入或輸出(開(kāi)漏結構(默認)或推挽結構),上電默認狀態(tài)由AD1和AD0決定??稍O置為L(cháng)ED模式。 |
9 | GND | Ground. 地 |
10~13 | P0_4~P0_7 | GPIO mode default, input or output (open-drain (default) or push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode. 默認GPIO,輸入或輸出(開(kāi)漏結構(默認)或推挽結構),上電默認狀態(tài)由AD1和AD0決定??稍O置為L(cháng)ED模式。 |
14~17 | P1_4~P1_7 | GPIO mode default, input or output (push-pull), the state after power on is decided by AD1 and AD0 terminals. Can be configured as LED mode. 默認GPIO,輸入或輸出(推挽結構), ,上電默認狀態(tài)由AD1和AD0決定??稍O置為L(cháng)ED模式。 |
18 | AD0 | I2C device address, connect to VCC or GND,and control the default state of GPIOs (see table 1)。 I2C器件地址選擇,接VCC或GND,并設置GPIO狀態(tài)(見(jiàn)表1)。 |
19 | SCL | I2C serial clock. I2C時(shí)鐘 |
20 | SDA | I2C serial data. I2C數據 |
21 | VCC | Power supply. 電源輸入端. |
22 | INTN | Interrupt output pin, open-drain, need external pull-up resistor; active low. 中斷輸出,開(kāi)漏結構,需外部上拉電阻;低有效 |
23 | RSTN | Hardware reset pin, active low; internal 100 kΩ (typical) pull-down resistor. 硬件復位,低為復位;內部下拉100 kΩ(典型值)電阻 |
24 | AD1 | I2C device address, connect to VCC or GND,and control the default state of GPIO (see table 1)。 I2C器件地址選擇,接VCC或GND,并設置GPIO狀態(tài)(見(jiàn)表1)。 |
EP | GND | Provides both electrical and thermal connection from the device to the board. Connect to the system ground. 接地。 |
