flipdigit 0.1.0

Small flip digit library

FlipDigitPython

Description

This library has for goal to control the Small 7-segment displays by alfazeta.

Requirement

The only library needed for this to work is pyserial. Basic installation can be made like so:

pip3 install pyserial

or by using the provided requirments.txt file:

pip3 install -r requirments.txt

How to use

Simple digit

You can simply declare a FlipDigit like so:

from flipdigit import *

# myDigit = FlipDigit('/dev/tty0') 	# Linux com port
myDigit = FlipDigit('COM6') 		# Windows com port

This use the default configuration of a digit: 9600 baud with adress set as 0xFF.

Then you can either send the data code to enable or not a segment following the pattern shown there:

The code is then going from a for the lsb to g for the msb

As example, a 0 is 0b111111 or 0x3F:

myDigit.set_segments(0x3F)

or you can directly send the number you want like so:

myDigit.set_number(0)

Examples:

• segment_example.py
• number_example.py

Configuration

You can easily change the configuration of a digit like so:

myDigit = FlipDigit('COM6')	#we use a digit with default configuration

myDigit.set_serial_speed(SerialSpeed.S_115200)
myDigit.set_address(0x01)

The digit has now the address '1' and the baudrate is set to 115200 bauds.

Now the digit need to be used like so:

myDigit1 = FlipDigit('COM6',SerialSpeed.S_115200,0x01)

Examples:

• config_example.py

Multiple digit

You can easily use multiple digit since they share a static serial attribute. Be careful, only the first digit serial configuration will be taken in account!

myDigit1 = FlipDigit('COM6',SerialSpeed.S_115200,0x01)
myDigit2 = FlipDigit('COM6',SerialSpeed.S_115200,0x02)

myDigit1.set_number(1)
myDigit2.set_number(2)

Examples:

• multiple_digits.py

Multiple digit in sync

In the previous example, the set_number is not made in sync. It is possible to send the set_number or set_segments and then have all the digit refreshed at the same time using the SyncMultipleFlipDigits object like so:

myDigit1 = FlipDigit('COM6',SerialSpeed.S_115200,0x01)
myDigit2 = FlipDigit('COM6',SerialSpeed.S_115200,0x02)

mySyncDigits = SyncMultipleFlipDigits([myDigit1, myDigit2])
# now that the digits are part of a SyncMultipleFlipDigits, they won't be refreshed automatically


myDigit1.set_number(i)	 		
sleep(1)
myDigit2.set_number((i+1)%10)
sleep(1)

mySyncDigits.sync_refresh() # myDigit1 and myDigit2 are refreshed only here!

Examples:

• multiple_sync_digits.py
