MRAA and UPM Python3 use

[Jos Scheelen]

Hello, I will try to make the question mores specific. Any suggestion related to solve this issue is highly appreciated.

This is the situation.

This code works fine, MRAA only :

#!/usr/bin/env python3
import mraa
board_type = mraa.getPlatformType()
print (" Board type", board_type)
board_name = mraa.getPlatformName()
print (" Board name", board_name)
mraa_version = mraa.getVersion()
print (" MRAA Verson = ", mraa_version)
for x in range(0,40):
mraa_pin_name = mraa.getPinName (x)
print (" Pin ", x, " name = ", mraa_pin_name)

This code works also fine, MRAA and UPM :

#!/usr/bin/env python3
from time import sleep, localtime
DIO = 8
CLK = 7
from upm import _pyupm_tm1637 as TM1637
getVersion = TM1637.getVersion()
print ("Version TM1637 = ",getVersion)

This code works not, MRAA and UPM based on UPM examples included with the installation of UPM :

This is the example python code
I tried with and without the _ wto different responses.

./tm1637.py
Traceback (most recent call last):
File "./tm1637.py", line 27, in <module>
from upm import pyupm_tm1637 as tm1637
ImportError: cannot import name 'pyupm_tm1637' from 'upm' (/usr/lib64/python3.8/site-packages/upm/init.py)

./tm1637.py
Traceback (most recent call last):
File "./tm1637.py", line 62, in <module>
main()
File "./tm1637.py", line 37, in main

The code used (based on the installedexamples during the UPM installation process.)

#!/usr/bin/env python3
from future import print_function
import time, signal

Two different tries ...

from upm import pyupm_tm1637 as tm1637

from upm import -pyupm_tm1637 as tm1637

def main():
# Register exit handler for normal Ctrl+C exit
def SIGINTHandler(signum, frame):
raise SystemExit
signal.signal(signal.SIGINT, SIGINTHandler)

# Create a display object on pins 0 CLK and 1 DIO
display = tm1637.TM1637(0, 1)
dots = True

# Get local time
myTime = time.localtime(time.time())
print(time.strftime("System time: %H:%M", myTime))
print ("You can adjust your time zone by setting the TZ environment variable.")

# Draw a box for 3 seconds using 7-segment encoding
display.write(0x39, 0x09, 0x09, 0x0f)
time.sleep(3)

# Loop indefinitely
while True:
	# Update and display time
	timeString = time.strftime("%H%M", time.localtime(time.time()))
	display.write(timeString)
	# Toggle colon
	display.setColon(dots)
	dots = not dots

	# Sleep for 1 s
	time.sleep(1)

if name == 'main':
main()
