Tim RiemannEigentlich müsste ich die 64 Pixel Boards auch mal zum laufen bringen. Habe noch 8 Stück davon. 24V und <a href="https://mastodon.social/tags/RS485" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RS485</a> / <a href="https://mastodon.social/tags/DMX" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#DMX</a> sollte ich hinbekommen. Notfalls hätte ich noch einen alten Butler XT2 da. Der sollte die auch ansteuern können.

patagonaI've recently discovered the ISDT CM1620 charging modules.They're pretty cheap (~140€) and promise some pretty good specs: - ~11-70V / 1100W input - ~8-70V 20A / 1000W output - LiHv, LiPo, LiFe 2-16S balance charging - Control via Micro-USB, Bluetooth, RS485, CAN or an optional controller with displayFrom our tests, they work fine, even at max load (16S 15A).However, they do have some quirks...(Thread)<a href="https://chaos.social/tags/ISDT" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ISDT</a> <a href="https://chaos.social/tags/CM1620" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CM1620</a> <a href="https://chaos.social/tags/BatteryCharger" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#BatteryCharger</a> <a href="https://chaos.social/tags/RS485" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RS485</a> <a href="https://chaos.social/tags/ReverseEngineering" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ReverseEngineering</a> <a href="https://chaos.social/tags/USBC" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#USBC</a>

scyOkay, I’m … confused.I’m using an <a href="https://chaos.social/tags/Arduino" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Arduino</a> MKR 485 shield¹ and an <a href="https://chaos.social/tags/ESP32" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ESP32</a> to talk to what I assume is a half-duplex <a href="https://chaos.social/tags/RS485" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#RS485</a> bus. I’ve connected the Y, Z, and IsoGnd terminals to the bus.I can receive data when pulling the RE pin low (it’s active low), no problem. But sending didn’t quite work. I thought I should only pull DE high while I’m sending, else I disturb the bus, but I found that I can keep it high all the time and communication still works. Why is that?¹ <a href="https://docs.arduino.cc/hardware/mkr-485-shield" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://docs.arduino.cc/hardware/mkr-485-shield</a>
