I'm trying to get an SPI device working with codesys for the Raspberry PI, and I'm using the MPC3008 example as a template.
I've just installed codesys 220.127.116.11, and then the codesys control for Raspberry PI 18.104.22.168 package.
However, when I open the example MCP3008Temperature.project, I get 14 error messages about missing libraries --
They are not (obviously) in the 22.214.171.124 PI libraries (I tried installing everything), and the library manager doesn't show anything
for download missing libraries.
Am I doing something wrong? Is the example broken?
How do I get a working example so that I can understand and modify it?
The project was created with a different version of the IDE with different
installed devices. This is a common issue. The key actions are:
Update device did the trick.
A followup question -- when I was first looking through the MPC3008 example project, I was looking at the library source.
Now, even if I open the un-updated project, I can't bring up the library source.
How do I open it to examine it?
Nevermind. Of course I find it just after I ask the question...
