GMLAN SWCAN high voltage wakeup support

Do you support GMLAN SWCAN high voltage wakeup and how please?

Hi Bregal,

Thanks for reaching out.

Based on this: “To wake the control modules connected to the low speed GMLAN serial data bus, a high voltage wake up pulse is sent out over the bus, the voltage level of the pulse is +10 volts”

Here’s the link if you want to read it yourself.

As long as the high voltage pulse is on the VCC line (where we get power from), the SPM should be able to detect that and wake the device up. And in our documentation page, you’ll find how to do it: Power | AutoPi Documentation.

Hope this answers your questions.

Best regards,
Tony, AutoPi
