TM1650 Arduino library for 2 x 8 led display

[StealthRT]

Hey all I am using a 2 digit 8 segment TM1650 Arduino library and I can't seem to find the setting for that? I can only find TM1650_DISPMODE_4x8 and TM1650_DISPMODE_4x7. No 2x8.

My setup looks like this when running the code below:

My Arduino nano code:

#include <TM1650.h>
#include <TM16xxDisplay.h>
//              [data Pin]
//              |  [clock Pin]
//              |  |  [num Digits]
//              |  |  |  [activate Display]
//              |  |  |  |     [intensity]
//              |  |  |  |     |  [display mode]
//              ↓  ↓  ↓  ↓     ↓  ↓
TM1650 display1(2, 3, 2, true, 7   );

void setup()
{
}

void loop()
{
   int n;

   for (n = 0; n < 10; n++)
   {
      //                             [nNumber]
      //                             |  [byte bDots]
      //                             ↓  ↓
      display1.setDisplayToDecNumber(n, 0b0000);
      delay(250);                               
   }
}

If someone could let me know how to go about modifying the code in order to allow me to use just 2 digitals instead of 4 then that would be great!

//              |  |  [num Digits]
//              |  |  |  [activate Display]
//              |  |  |  |     [intensity]
//              |  |  |  |     |  [display mode]
//              ↓  ↓  ↓  ↓     ↓  ↓
TM1650 display1(2, 3, 2, true, 7   );

void setup(){}

void loop(){
   for (byte n = 0; n < 99; n+=16)   {
      //                             [nNumber]
      //                             |  [byte bDots]
      //                             ↓  ↓
      display1.setDisplayToDecNumber(n*100, 0b0000);
      delay(250);                               
   }
}

Just displays 9.9.

And before your edit this is what that code resulted in:

which code? you say my is not compiling.

TM1650.h lib has no member init() and setDisplayToDecNumber(), but has clear(). speak to lib developer.

[StealthRT]

Looking at the pcb tracks only power, gnd, data and clock tracks seem to be going to the correct places. All others do not seem to be aligning like they are in the datasheet? Or maybe i am looking at it incorrectly?

[kolaha]

what is the difference between tm1637-tm1638-tm1650 ?

[StealthRT]

@kolaha

tm1637

As the github page says:

TM1616	7 x 4	n/a	DIN/CLK/STB
TM1620	8 x 6 - 10 x 4	n/a	DIN/CLK/STB
TM1628	10 x 7 - 13 x 4	10 x 2 multi	DIO/CLK/STB
TM1630	7 x 5 - 8 x 4	7 x 1 multi	DIO/CLK/STB
TM1637	8 x 6 (common anode)	8 x 2 single	DIO/CLK
TM1638	10 x 8	8 x 3 multi	DIO/CLK/STB	Anode/Inverted/QYF*
TM1640	8 x 16	n/a	DIN/CLK	Anode*
TM1650	8 x 4	7 x 4 single	DIO/CLK	Not real I2C SDA/SCL
TM1652	8 x 5 - 7 x 6	n/a	DIN	Single data line
TM1668	10 x 7 - 13 x 4	10 x 2 multi	DIO/CLK/STB

And looking at the datasheets for the 3 the pinouts look different (yet none look like the pinout of the pcb) and more pins.

TM1637:

TM1638:

TM1650:

[kolaha]

#include <TM1650.h>
#include <TM16xxDisplay.h>

TM1650 module(2, 3, 4);  
TM16xxDisplay display(&module, 4);  

void setup() {
  display.println(F("HELLO !"));
}

int nCount=0;
void loop() {
  delay(1000);
  display.print("Count:");
  display.println(nCount++);
}

[StealthRT]

Just trying you first display.println(F("HELLO !")); looks like this:
