以下程序可以直接跑在arduino UNO开发板上：

#include <Wire.h>

#define HW_RESET_PIN 8

void test_i2c()
{
    Wire.beginTransmission(0x48);
    Wire.write(0x00);
    Wire.write(0x01);
    byte x = Wire.endTransmission();
    Serial.println(x);
}

void tlc59108_config()
{
    /* Set normal mode */
    Wire.beginTransmission(0x48);
    Wire.write(0x00);
    Wire.write(0x01);
    Wire.endTransmission();

    /* Set FULL ON */
    Wire.beginTransmission(0x48);
    Wire.write(0x0c);
    Wire.write(0x55);
    Wire.endTransmission();

    Wire.beginTransmission(0x48);
    Wire.write(0x0d);
    Wire.write(0x55);
    Wire.endTransmission();


}

void tlc59108_setBrightness(byte dutyCycle)
{
    /* Set PWM mode */
    Wire.beginTransmission(0x48);
    Wire.write(0x0c);
    Wire.write(0xaa);
    Wire.endTransmission();

    Wire.beginTransmission(0x48);
    Wire.write(0x0d);
    Wire.write(0xaa);
    Wire.endTransmission();

    Wire.beginTransmission(0x48);
    Wire.write(0x02 | 0xa0);
    for (byte i = 0; i < 8; i++) {
        Wire.write(dutyCycle);
    }
    Wire.endTransmission();
}

void tlc59108_reset()
{
    /* Reset */
    digitalWrite(HW_RESET_PIN, HIGH);
    delay(1);
    digitalWrite(HW_RESET_PIN, LOW);
    delay(1);
    digitalWrite(HW_RESET_PIN, HIGH);
    delay(1);

}

void setup() 
{
    /* Setup init */
    Wire.begin();
    Serial.begin(9600);
    pinMode(HW_RESET_PIN, OUTPUT);

    tlc59108_reset();
    tlc59108_config();
    tlc59108_setBrightness(0xf0);
}

void loop(){
    sweep();
}

void sweep() {
    Serial.println("Blinking...");
    delay(1000);
}
