I can't use MIP display (MIP display dosen't work).
junk-junk opened this issue · comments
I've trouble with MIP monitor.
I could use MIP monitor by mip_test_pigpio with a few changes (only clock speed).
however,When I run the pizero_bikecomputer, the screen lights up, but nothing is displayed (displays correctly in X-window).
[my setup guide in Japanese] says to use forked PyQtGraph, but I can't find it,Is this the cause?
[GENERAL]
display = MIP
OS:Raspberry pi OS bullseye
I installed qt5 according to https://forums.raspberrypi.com/viewtopic.php?t=346805
thank you.
Hi,
follow software documentation.
https://github.com/hishizuka/pizero_bikecomputer/blob/master/doc/software_installation.md#manual-execution
displays correctly in X-window
Maybe the execution command is incorrect.
$ QT_QPA_PLATFORM=offscreen python3 pizero_bikecomputer.py
If you don't mind, I would be glad to see pictures of the examples you have made.
I have never seen anyone buy and build a MIP display before.
Enjoy!
Hi,hishizuka.
Thank you for comment
$ QT_QPA_PLATFORM=offscreen python3 pizero_bikecomputer.py
umm, window is disappered in x-window, but MIP display still blank(or displayed last image).
If you don't mind, I would be glad to see pictures of the examples you have made.
I have never seen anyone buy and build a MIP display before.
Of course!
but,It isn't assembled yet.
It will be equipped with an 18650 battery instead of Pi juice.I'll share it when it's finished!
Hi @junk-junk ,
great!!!
Is it possible to see the logs of the program when it runs?
If there are parts you don't want me to see, you can delete them.
Hi, @hishizuka,
I think there no errors,so I wonder why it's not working.
Please let me know if there is anything else I can do.
Since it's indoors, GPS isn't working ;-(

Qt version is 6.4.2, so it must be bookwarm?
Maybe if you install libqt6svg, it should work.
Simply, here are the steps I posted
$ sudo apt install python3-pyqt5 python3-pyqtgraph
But you seem to install python3-pyqt6 in Bookwarm. Then,
$ sudo apt install python3-pyqtgraph python3-pyqt6 libqt6svg6
Sorry,
I made a fatal mistake. Pin assign of SCS was changed from GPIO 22(15 pin) to GPIO 23(16 pin). So please change.
Hi,
sorry,late reply. I was explaining my credit card statement to my wife (especially about the sushi restaurant).
Qt version is 6.4.2, so it must be bookwarm?
Yes,I'm using bookworm. So, I tried two method.
- One: I installed python3-pyqt6
python3-pyqtgraph is already the newest version (0.13.1-4).
python3-pyqt6 is already the newest version (6.4.2-1+rpi1).
libqt6svg6 is already the newest version (6.4.2-2).
- I installed the old version (sudo apt build - dep python three - pyqtgraph=0.11.1-1).
However, there was no change. The window opens in the X-window, but it is not displayed in the MIP display in both case.

Hi @junk-junk ,
I ate sushi yesterday, too.
First, did the latest mip_test_pigpio.py work? (Updated yesterday.)
If Yes, then it is a matter of installation or activation method.
Whenever you use MIP display, you must activate it with QT_QPA_PLATFORM=offscreen.
Without it, the logic for flowing data to the SPI will not work.
QT_QPA_PLATFORM=offscreen python3 pizero_bikecomputer.py
If this still does not work, then it is an installation problem.
PyQtGraph is OK with the latest version.
Hi,@hishizuka
Thanks you for your great help.
Sorry,,,I had a big mistake....
First, did the latest mip_test_pigpio.py work? (Updated yesterday.)
It doesn't work, and I realized my miswiring.
I installed the hardware according to the py_mip_sample and Japasese document.
But, in pizero_bikecomputer, CS is changed from IO15 to IO16. So, I rewired the cable and it worked!
Thank you!
Best regard!
Hi @junk-junk ,
that was good.
Enjoy!!!
