The digital outputs of the RevPi Compact Module cause a peak when switching on, what can I do?
Yes, this is unfortunately a known issue. We are currently working on this bug. Unfortunately, we can't influence the behaviour. The output pins on the Compact come directly from the compute module, and we have no influence on this behaviour at boot time.
...
What was the solution?
There is a workaround that fixes this behaviour on reboot, see here:
What is the XXX chip used to multiplex analogue to digital conversions (item 2)?
...
The multiplexer: DG408LE
the selection of the analog input is done via GPIO6, GPIO12 and GPIO13
GPIO | DG408LE |
|---|---|
GPIO6 | A0 |
GPIO12 | A1 |
GPIO13 | A2 |
How can I access the Digital Inputs / Outputs from Codesys?
...
No, the range is 0 - 10 V.
8 x analog Inputs |
2 x analog Outputs |
