Yesterday I posted this on Mastodon (post link) I'm building a new habit here on Mastodon: instead of liking, I try to reply to at least 3 posts, especially...
So we're using an ESP32S with a TJA1050 transceiver and basically we're using this setup to operate a rover using ROS2 Humble and MAVLink commands, so it has a lot of modules like actuators, PDB, mini-arm, and etc connected through a CAN bus network. Now the issue is that we will be using multiple BLDCs for our rover's arm and these motors continuously send out updates (or heartbeats or sth) so using these BLDCs in the same network seems like the MCU will lag or slow down and just be downright ineffective. So is there any way to isolate the motors to a different network or CAN line? I was thinking of adding another MCU on top of the ESP32 to only handle the motors but is there an alternative to this approach, preferably one without adding more hardware? submitted by /u/Sadhya [link] [Kommentare]
Goodhart's Law: when a measure becomes a target, it ceases to be a good measure. The Fed's rate projections were a measure of where policy was heading. The moment Trump made them a political target, they stopped reflecting reality and started reflecting intention. The market priced the intention. Reality reasserted itself. submitted by /u/zakoal [link] [Kommentare]
