Hi,
I use Codesys 3.5.16.10 My project include Raspberry Pi SL SPI master for MCP3008. It work with Raspberry connected. But in Simulation mode compiler returns errors:
[ERROR] raspberry pi peripherals, 3.5.13.0 (3s - smart software solutions gmbh): transferExt [spiMaster]: C0032: Cannot convert type 'POINTER TO spi_ioc_transfer' to type 'UDINT'
[ERROR] raspberry pi peripherals, 3.5.13.0 (3s - smart software solutions gmbh): init [spiMaster]: C0032: Cannot convert type 'POINTER TO DINT' to type 'UDINT'

Hi,
you need to report this in the CODESYS store -> my question -> bug report
Seems that the simulation dooes not work with raspberry pi peripherals, 3.5.13.0

Well,
Their answer was:
"Dear,
you can also restart the Pi and used again for 2h in demo.

Mit freundlichen Grüßen / Best regards"

No bad at all :)

Hi,
I have a similar issue - we have been using codesys V3.5.16.20
Do you have any suggestions or confirmation that this will work with a different version of codesys and Pi extension

I fear you need to update if you need a solution for this.
