rpi-tm1638's Issues

The clearDisplay() method . It seems to bring the object in a not desirable state.

Thanx a lot for the nice library. It saves a lot of ime for me and my students. However there seems to be something "funny" about the clearDisplay() method . It seems to bring the object in a to me unknown state. Not unrecoverable, but maybe not desirable.

TM.clearDisplay()
TM.segments[0] = '123'
TM.turnOn(1)
TM.segments[0] = '123'

"""
... Here I am stuck!
...
... The only way to recover is to initialize the objec again
... """

TM = TMBoards(DIO, CLK, STB, 0)
TM.segments[0] = '123'

No display, module is ok

Hello,

Thank's for your code !

I have no display on my TM1638.

test_TM.py paramètre is :

# my GPIO settings (two TM1638 boards connected on GPIO19 and GPIO13 for DataIO and Clock; and on GPIO06 and GPIO26 for the STB)
DIO = 19
CLK = 13
STB = 06, 26

Launch test script :


root@raspberrypi(rw):/opt/rpi-TM1638# python test/test_TM.py 
Traceback (most recent call last):
  File "test/test_TM.py", line 25, in <module>
    TM.leds = (True, False, True)   # set the three first leds
AttributeError: can't set attribute

If i comment TM.leds ligne :

- TM.leds = (True, False, True)   # set the three first leds
+ #TM.leds = (True, False, True)   # set the three first leds

Launch :

root@raspberrypi(rw):/opt/rpi-TM1638# python test/test_TM.py 
root@raspberrypi(rw):/opt/rpi-TM1638#

I have no display on the TM1638, only the Power LED is red

Have I wired correctly?

Cable_TM1638_PI

I have just one TM1638 on PIN 26, does your library work for only 1?

In python3 say :

root@raspberrypi(rw):/opt/rpi-TM1638# python3 test/test_TM.py 
  File "test/test_TM.py", line 8
    STB = 06, 26
           ^
SyntaxError: invalid token

Thank you in advance for your help,

Q: How to properly init several daisy-chaned boards?

Hi !

Thanks for so useful piece of sofware.
I have problem to determine how to properly init several daisy-chaned boards.

DIO = 19
CLK = 13
STB = 26
TM = TMBoards(DIO, CLK, STB, brightness=7)

I see this code in your original source.
self._nbBoards = len(self._stb)

Am I correctly assume that for multiple boards one should create STB as a list of pins, e.g.
STB = [26, 27], where STB0 = 26, STB1 = 27

Thanks in advance.

Switch Status Determination

Hello,

First of all thanks a lot for the lib.

I'm having a bit difficulty understanding this line here.

I could be wrong but it looks like in case K==0 the boolean would only work for switch 1 (n=0) and switch 5 (n=4), correct?

When S1 is pressed sw = [1, 0, 0, 0] and when S5 is pressed sw = [16, 0, 0, 0], in all other cases sw[K] would always be 0 and the function would not return a key pressed status.

Note: this is related to #4
If it's not fixed it will report error at L171.
