引腳號(hào) | 名稱 | 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(rèn)GPIO模式，輸入或輸出（推挽結(jié)構(gòu)），上電默認(rèn)狀態(tài)由AD1和AD0決定。可設(shè)置為L(zhǎng)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(rèn)GPIO模式，輸入或輸出（開漏結(jié)構(gòu)（默認(rèn)）或推挽結(jié)構(gòu)），上電默認(rèn)狀態(tài)由AD1和AD0決定。可設(shè)置為L(zhǎng)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(rèn)GPIO，輸入或輸出（開漏結(jié)構(gòu)（默認(rèn)）或推挽結(jié)構(gòu)），上電默認(rèn)狀態(tài)由AD1和AD0決定。可設(shè)置為L(zhǎng)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(rèn)GPIO，輸入或輸出(推挽結(jié)構(gòu)), ，上電默認(rèn)狀態(tài)由AD1和AD0決定。可設(shè)置為L(zhǎng)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(shè)置GPIO狀態(tài)（見表1）。 |
19 | SCL | I2C serial clock. I2C時(shí)鐘 |
20 | SDA | I2C serial data. I2C數(shù)據(jù) |
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，開漏結(jié)構(gòu)，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(fù)位，低為復(fù)位；內(nèi)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(shè)置GPIO狀態(tài)（見表1）。 |
EP | GND | Provides both electrical and thermal connection from the device to the board. Connect to the system ground. 接地。 |
