I hope I can figure out how to build a opcua (open62541) gateway .. maybe the chip is too small to do this but i'll try Some example scripts on how to use the module would have made the start a little easier.
I have got the dual can-bus on teensy and everything is soldiered, i have been trying to make it work using the recommended library but still no luck!!, is there a way to show how to connect it ? i Tried using CAN0 and CAN1 and the alternativeCAN0.
is there way that shows how to get it done and how to make it work please that will be so helpful.
Bought the CAN32 to play with NMEA2000 (boat can network) and the ESP32. Everything works as promised and the price is very reasonable.
As noted in other reviews, it would be helpful to have the schematic or at least more details on the connections but it has been posted since then. I had doubt about how the SDCard is connected, it is SPI and MISO/MOSI/CLOCK are 19/23/18. As noted in the other comments CS for the card is 17.
With all of this I was able to make a NMEA2000 logger that records all traffic to the SDCard (see https://github.com/ttlappalainen/NMEA2000_esp32 for the driver) in one afternoon.
Thanks for putting this product to market - I look forward to the next revision!
Bought this for sniffing traffic on industrial CAN networks and some car hacking on the side. Can't get any smaller, and is a perfect fit on the Teensy 3.6. The seller is in the Czech Republic, so if you are a US buyer like me, be patient. He shipped my order off very quickly, but our wonderful USPS made sure to add the delays in. Nothing at all to do with the seller. Arrived, soldered up, and worked perfectly on the first try using an example sketch from the recommend library. The dual CAN is already proving very useful - I was logging frames from two buses running at two different baud rates, simultaneously. My only regret at this point is not buying several of these. The Teensy plus CAN is a great combination, especially if you plan to get creative with your vehicle bus.
I looked all over to find a small RGB metal button that came in low quantities and in high quality. It works great for what I need it to do and it took a month for it to come in from the day I placed my order. My review:
Pros: -Great Size -Nice vibrant colors -smooth operation Cons: - It's common cathode and not common anode (harder to use with led controllers, so I have to convert it) -PCB pads could be bigger or easier to solder too.
This is a really nifty add-on for the Teensy. Well built, sturdy, Definitely in keeping with the extremely small size philosophy of those who work with Teensy-related products. I plan on buying more, when I get onto the next project.
I didn't want to rate the documentation, as none provided. There is a very nice discussion of this in Paul S's Teensy Wiki pages, which is all I needed.
