Waveshare USB to CAN Adapter Model A, STM32 Chip Solution, Multiple Working Modes, Multi-System Compatible

No direct C# code example or serial port library / DLL was provided with the product.The adapter uses the CH340 USB to Virtual serial port low level driver.A serial driver / api has to be written / purchased / integrated to use the product with your C# application.After requesting an example from Waveshare, I received a mixed English / Chinese set of code that was far too bloated, when all I needed was a simple C# App and serial API DLL.I had limited success writing a pure C# driver for this adapter that was efficient and reliable over the standard SerialPort Class. A lower level Win32 driver is needed to handle high speed serial port processing reliably and efficiently, which a USB to CAN interface will require, especially for 250k and above CAN rates. The device supports 2M baud for the serial side as a default, which supports what I have stated.I was not able to get consistent or reliable received data and the adapter required significant delay between transmitted packets for them to be sent successfully (no packet sent or corrupted data). This was confirmed by Waveshare.Perhaps, if someone has had success with this product, they will provide details on how that was achieved.Update 4/6/2024I applied a Win32 Serial Port API with very thin Data Received Event code (just loads serial data into a buffer and exits) and was able to generate more consistent results for received data, but found that I had to drop down to 1228800 baud to keep bytes from being dropped by the serial interface. I just ran a few tests receiving 2.5M bytes of data without missing bytes, so perhaps that was part of the issue.I've not gone back to test transmitted data again but based on Waveshare's support feedback, I don't expect this is going to improve much.

This device creates an interface between controller area network (CAN) 2.0a and 2.0b capable machines (typically vehicles) and your PC running Windows/Linux (serial communications only up to 1Mbps, max). The instructions are quite clear and walk you through setup.The box includes a USB extension cable so you don't have to connect anything so close to to the wiring harness of your vehicle. I really like the ability to detach the terminal so you can easily disconnect and reconnect as required.Check the manufacturer's website for current documentation and software drivers.

L'analizzatore adattatore CAN USB Waveshare offre funzionalità complete per l'analisi e il monitoraggio del bus CAN, tra cui raccolta dati, controllo di ricezione e trasmissione, analisi dei dati e monitoraggio di rete. Supporta entrambi gli standard CAN2.0A e CAN2.0B con una gamma di baud rate da 5kbps a 1Mbps.Vanta quattro modalità operative per coprire diverse esigenze: normale, loopback, silenziosa e loopback silenziosa. Allo stesso modo, offre flessibilità nella trasmissione dati con opzioni come invio singolo, multiplo, manuale, temporizzato e ciclico.L'adattatore include comodamente un cavo di prolunga USB e un piccolo cacciavite. Funziona perfettamente su sistemi Windows (da XP a 11) e Linux (Raspberry Pi OS, Jetson Nano Ubuntu e altri), grazie al chip CH340 e ai driver preinstallati su Windows.Tuttavia, il software applicativo per sfruttare tutte le funzionalità deve essere scaricato separatamente dal sito web di Waveshare.Nel complesso, l'analizzatore adattatore CAN USB Waveshare è un'ottima scelta per la sua versatilità, affidabilità e compatibilità. Rappresenta una soluzione ideale per hobbisti, professionisti e sviluppatori del settore CAN bus.Considera l'adattatore Waveshare se sei alla ricerca di uno strumento ricco di funzionalità per l'analisi e il monitoraggio del tuo bus CAN.

Article de qualité, livré dans un sachet antistatique et comprenant tournevis (les vis du bornier sont petites) et câble de prolongation USB (mâle-femelle) avec tore d'antiparasitage (ce qui est assez rare pour être cité).Dommage qu'aucun descriptif, mode d'emploi, conseils d'utilisation ou lien n'accompagne le produit.

Comes well packed in a little box. Nice thing is it includes and USB extension cable (useful for other moments in a developer bench...).A small screw driver is included, too.The device works well and was recognized instantly by Win7 and Win10/11, mostly because it is based on CH340 and I already had the driver installed.For the application software, it was necessary to dig it out, searching for manufacturer name, CAN-A and wiki.They should have included a link to their page on the box, at least.
