lagging at >125kbps #1

Open apple2ms opened 1 year ago

apple2ms commented 1 year ago

Has anybody tested it at higher speeds for example 500000? The signals are lagging. Is there any way to solve this? image

This library is a very thin wrapper around the can2040 project's code (see the README in this repo). My use-case is 125kbps at which it works fine. I would suggest opening an issue in the can2040 repo or adding to my existing 'discussion' issue there. It may be that Kevin has addressed this issue already, but as I know of no way for an Arduino library to automatically depend on a non-Arduino codebase, I have to track and include Kevin's changes manually. If he has already addressed this, I will grab his changes and update this library.

It would help if you have a ability to test Kevin's code independently, to remove any possibility that the Arduino toolchain (which is different to what Kevin uses) is affecting performance.

Hi, Do you plan on integrating the latest changes from Kevin's library? I can see that after https://github.com/KevinOConnor/can2040/pull/24 it might be possible to run two instances of it. Would be great if we can get that on arduino. I am willing to test because I already have a few boards with 2x can transceivers.

I usually pull in upstream changes when I notice them, so thanks for the heads up. Give me a couple of days as it's a manual copy and paste process.
