TM1638 LED Module & Arduino Leonardo - Problems !

Other Hardware Displays

Hi,

Firstly thank-you for reading this posting.

I have a TM JY-MCU JY-LKM1638

600×600 37.3 KB

I have been using the Arduino Uno for my projects and have had great success.
My favorite has been using the module above as a racing dash for Project Cars supported with Batrako
Api for the program which provides serial data to the Arduino Uno, via Pins;

const int DATA_PIN=8;
const int CLOCK_PIN=9;
const int STROBE_PIN=7;

Now here is my problem, i have connected the Arduino Leonardo running the same sketch and pins with no avail. It just does not work.

I have looked a pin out diagrams, and believe that Leonardo PIN 13 is CLK, but still nothing

If anyone can see what i am missing it would be wholly appreciated as i am stuck ??

I think it may not be sending any serial data, or something.

Thanks.

Guessing here!

Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL serial data using the ATmega32U4 hardware serial capability. Note that on the Leonardo, the Serial class refers to USB (CDC) communication; for TTL serial on pins 0 and 1, use the Serial1 class.
