CAN/FD Bus Sniffing From a Browser

The CANFDuino platform can be turned into a handy two-port CAN/FD sniffing tool for basic monitoring of bus traffic without any fancy PC-side software. What’s interesting is that a very old-school terminal protocol developed in the 1970’s for VT100 terminals plays a part. The ANSI X3.64 protocol provided a really simple method for manipulating cursor location and printing to the screen driven by the embedded device (a duty that nowadays is implemented in PC software that can be OS and driver dependent as well as licensed). Enter modern day browsers, for which terminal-emulator web pages have been developed. Or you can turn to the ubiquitous, free, and reliable terminal program PuTTY. Basically any PC-side “terminal emulator” can be used to “CANalyze” bus traffic, regardless of how it runs or what OS it’s on (provided USB to serial drivers). It’s not the most beautiful or elaborate solution, but hey, it’s simple, easy, and cheap. The following update delves deeper into this application of CANFDuino. Read the full update.

Good News on Lead Times

We have some good news for backers! We are happy to announce that we have a high level of confidence the second batch of CANFDuinos will ship by October, 2022. (Early orders will still ship within the next couple of months.) In order to make this happen, we were forced to swap out a single component. CANFDunio was originally designed to run on Microchip's ATSAMC21G18A, which has lead times into late 2023, so we are temporarily replacing that part with the slightly less powerful ATSAMC21G17A variant. This modification will not affect the available IO but it will change two specifications: Flash Memory Space will be 128 K rather than 256 K and RAM space will be 16 K rather than 32 K. This update describes what that means in practical terms. (Hint: not very much.) Read the full update.

Speed Test - CANFDuino vs. SPI CAN Shields

It's true there are several CAN and CANFD shields on the markets with several supporting libraries. Many of them are designed for use with popular open-source platforms like Arduino UNO and ATMega. So why not just use one of those? For this week's update, I decided to write about one of the primary motivations for using an open-source board that is purpose built for CAN projects as opposed to a "stacked-shield SPI-based" approach: the need for speed.

Long Lead Times for Subsequent Backers

Thank you for supporting CANFDuino. We are really excited to hear where our backers go with this product, and we can't wait to get one into your hands! Unfortunately, we have depleted our first batch of stock and, due to supply chain issues, we are now looking at a 12 to 18-month lead time. That being said, there are only a handful of components holding us back. If we get some relief in supply, we will place our order, produce our next batch, and complete fulfillment as soon as possible. Thank you for your continued support! Read the full update.
