LEDs are not blinking on ValueCAN3 #6

  1. When we use ValueCan3 with amrbian built with 4.13.15-sunxi kernel and intrepid software is built with following revisions, we see that LEDs are working fine. ValueCan4 is not supported in this case by intrepid software.

  1. When we use ValueCan3 with armbian built with 4.19.50-sunxi kernel (we had to upgrade kernel to make newer versions of intrepid software compilable), then LEDs are not working at all, but CAN messages are actually coming (we can send from host and receive them). If we use ValueCan4 in the same setup here, then LEDs work fine. Following intrepid versions are used in this case:

Hi tysonite,

https://github.com/intrepidcs/icsneoapi is now deprecated, and is no longer used by the latest https://github.com/intrepidcs/icsscand. Now, building https://github.com/intrepidcs/icsscand will inherently build https://github.com/intrepidcs/libicsneo into it.

https://github.com/intrepidcs/libicsneo is our new fully featured open source device communication API, completely superceeding the https://github.com/intrepidcs/icsneoapi. All features from the old API are now implemented in the new one.

The new device communication API is most likely where the bug exists for ValueCAN 3, so I'm making the bug report https://github.com/intrepidcs/libicsneo/issues/16 and closing this one. The bug should only affect the LEDs and should not affect other device functionality.

Let us know if you need anything else!
