I've ordered one interesting module from DealExtreme. Today I've ported code from Intel x51 example sourcecode. I played with driver on Arduino to make it more easier for younger players :) Library is bit improved, you can display numbers, your own segments, turn on red and green LEDs and read buttons. It works very nice. http://www.dealextreme.com/p/8x-digital-tube-8x-key-8x-double-color-led-module-81873 If you wan't true Arduino library for this module, I suggest you more advanced library based on my original code. It was improved by Ricardo Batista and supports also "chained" modules. ![]() Example code unsigned char numbers[] = {1,2,0x0A,0x0B,0x0C,0x0D,0x0E, 0x0F}; // Text: "Hello" unsigned char helloLCD[] = { 0,0b01110100, 0b01111001, 0b00111000, 0b00111000, 0b01011100, 0, 0}; // Text: "by Hub" unsigned char byHub[] = { 0, 0b01111100, 0b01110010 ,0 , 0b01110110, 0b00011100, 0b01111100, 0}; void setup() { TM1638_init(); TM1638_write_display(helloLCD); TM1638_write_LED(0b00011111 | 0b11111000 << 8); delay(3000); TM1638_write_display(byHub); } void loop() { unsigned char i, key; key = TM1638_read_key(); if(key < 8) { for(i=0; i<8; i++) numbers[i] = key; TM1638_write_numbers(numbers); // Alternate RED & GREEN LEDs TM1638_write_LED(((key % 2 == 0) ? (1 << key) : 0) | (key % 2 ? 1 << (key+8) : 0)); } } |
