Hi
I'm trying to connect a Catalex (catalex.taobao.com) digital tube display with a TM1637 chip to the GPIO's.
I looked in the docs but didn't find the instructions how to connect the display.
It has four pins. CLK, DIO, VCC, GND.
The VCC goes to the 3,3 v vcc connection and the ground goes to the ground.
Where do the CLK and DIO connections go.
Thanks !
There is an example patch for the "LKM1638" display board in archive/tests/io/spi_lkm1638.axh
This board uses a different chip (TM1638) and the board has 8 7-segment digits, 8 pushbuttons, and 8 bicolor led's. The example patch only deals with the pushbuttons and led's, not with the 7segment displays. Assuming the TM1637 and TM1638 are similar, it lists the connections that need to be made, and how to talk to it. The script code however will need to be adapted to the TM1637 registers.
