Node-red-node-pi-mcp3008 0.5.2

General

That would be a rude question.

It seems that the 0.5.2 version is not compatible with the Raspberry Pi 4 hardware. The node does not work.
The node run on Raspberry Pi 3 hardware.
Is there any plan to update this node-red-node-pi-mcp3008 in the near future?
It's actually difficult to continue a project using old hardware at this point.

I would like the new node-red-node-pi-mcp3008 version.

Welcome to the forum @tky27nrt

Are you using the same version of the Pi OS on the two devices?

What doesn't work ? Are there any error messages ? Are you using 32 or 64 bit version of the OS ? etc etc...

@Colin
thank you for your reply.

I am currently using the latest version of imager.
I tried it on both 32bit and 64bit.

@dceejay
thank you for your reply.

I tried 32bit and 64bit with the latest OS of imeger.
I have also installed the latest version of NODE-RED.

WebGUI On the flow screen, it will be displayed as [node inactive].
When checking the status on CUI, the following is displayed.
[ warn ] Info : mcp3xxx : Not running on a Pi - Ignoring node

I also checked the SPI settings using the GUI and CUI and they are turned on.

To this node developer. I would like you to create a version of the node that is compatible with Raspberry Pi 4.
Raspberry Pi 3 hardware is already difficult to purchase.

Can you run the command cat /proc/cpuinfo on the Pi4 and paste the result here please ?

(Please note that the underlying node library the node uses was last updated in 2021 and says it supports up to node16 - we may be able to get it to work but it's lifetime may be limited.)

hello, I thought that the mcp3008 was outdated and no longer used. If you want, I can rewrite the mcp3008 node. At the moment I have already written nodes for other adc chips. But I need to get a mcp3008.

@iiot2k
Thank you for your reply.
I am using it this time because it is available relatively cheaply in my country.
I understand that it is certainly an outdated ADC.
I really want to use something with a large number of channels.
I will also refer to your node.
