Thanks bro ! , almost only documentation existing on multiple displays, not so hard but very nice to see the code

@robojax Рік тому

Glad it helped

@dennisfriedl Рік тому

This tutorial was great. I am a bit new here and trying to use some of this design to work as a slot car lap counter. I'm close to getting it working but struggle with using two defined pinMode settings.When either button is depressed both displays increment the count. I can supply the sketch. I'm sure its something simple.

Hello! Thanks for your video. It helps me to start TM1637 based LEDs display. I have two thing to tell you: 1. The brightness work in 0x0 - 0x7 range. The TM1637 consider only first 3 LSB. The brighness adjust is made by duty factory of comon anode commnad of digits. For 0x0, the ON time is 40 microseconds, for 0x1 time is 82microseconds and so on till 0x7 where the time is 600 microsecons. The cicle time of all digits is 4,7 miliseconds. 2. I try to use only one pin for DIO. I conected DIO of the two displays togheter at pin 8, CLK of display1 to pin 9 and CLK of display2 to pin 10. They work OK. Each displays diferent value. That means is not necesary a distinctive pin for each DIO. They can be conected at the same pin. In code I define DIO1 and DIO2 at pin 8. In fact, all TM1637 receive a start comand on I2C, but anly one display will receive clock signal from microcontroler. Finaly, all TM1637 will receive a stop comand. If the driver TM1637 didn't receive clock signal between start and stop comand, the display will stay unchanged.

The second 5v is supplied by IOREF pin which for the UNO and MEGA is 5v. That connection is viewable at 1:54 and 1:59 in the video but not called out directly. The board used in video has two 5v pins marked. My Elegoo has the pin labeled as IOREF With the help of Robojax, the TM1637 is a joy to work with.

@breakerhun4859 5 років тому

Hi! Nice video. Just one note, you can use the same CLK pin to give clock signal for both device at the same time, there is no need to separate them. This way you can save 1 pin on your arduino.

@robojax 5 років тому

Perhaps you could if you wrote your own library. but with the current library you can't.

@breakerhun4859 5 років тому

@@robojax Okay, noted. Can you daisy chain 2 or more of these bigger led digits? so you connect to arduino on the right side pins and on the left side you connect another one in series with mother-mother jumper cables?

@robojax 5 років тому

No you can't. You will need this module : www.ebay.ca/itm/173060000548

@florinnica8909 5 років тому

Hello! I use the same DIO for two displays. They work properly also. You can save a number of pins equal to number of displays more than one.

hi Robojax... I'm a newbie in this area. For my assignment, I need to control 3 units of TM1637 by using PIC16F886. i managed to program the PIC but somehow the LED lights keep flickering. im using 5VDC input. Is it because of insufficient power supply?

@robojax 4 роки тому

Hi Norhafizah, the flickering is due to the delay in the loop. If you can, reduce the delay for example if you have it set to delay(300), then make it delay(200) or lower until it is corrected. Please reply here and let me know if it worked. salaam. Ahmad from Canada
