Hi,
I think J1587 is CAN so you would need a CAN transciever rather than RS485. Also there are over 40 CAN protocols and I don't think FC covers the one you want.

Hi, I am not sure if this is possible so just throwing it out there. I have an industrial HMI which I can read data from the PLC's controlling my lighting. In the PLC all the registers have a MODBUS address so it is simple to just read the registers I need. I am using a Raspberry Pi to read envoiron...

Hi Ben, Any chance you might get a fix before you break up for Xmas.

Hi,
The APA102 demo project (and others I have saved from it) do not save the port pins. I set the clock pin to G2 and MOSI to G25 and all works fine. When I re open the project they have reverted back to G10 & G11.

Hi, I have just tried a simple demo for WS2812, it simulates OK but when i try to compile and download to the device I get an error WS2812_Demo1.c:(.text+0x44c4): undefined reference to `nop' several times over. Also not sure if I have WS2812 or WS2812B but I get the same error. Target folder: C:\Us...

Hi Ben,
Thanks, quite a bit better now. It works much better than the (Pi hut) demo code. Lots of different effects to play with now over the weekend.

I may have to dig out the strips of LED's I have had for ages and get even more chistmassy now.

Hi, Thanks for the replies and the example. I did search for an example which is what I thought was what I had downloaded. I sort of thought it just demo'd everything possible so deleted what I thought I would not need. As for starting off with just the actual component, it is OK if you know what yo...

Hi, I have bought a christmas tree from https://thepihut.com/products/3d-rgb-xmas-tree-for-raspberry-pi The demo code does not seem to be very adaptable so I thought I would give FC a go. I have downloaded the APA102 example and stripped out what I do not need and am working through some options. I ...

Hi, I had the same issue where the program simulated OK but when downloaded would not work at all. Last time it was on an ESP32, this time on a Raspberry Pi and I would assume any device that uses network components. The issue is with no connection between the network comms and TCP_IP it appears to ...

Hi,
Thanks for confirming the length is OK.
Thank Martin, I had missed that value.
Still having issues but at least I know it is deeper that that.
