  • A great response by Sparkfun here, yet another reason to never doubt the integrity of your business. As it happens, I work in modern manufacturing test (trust me when I say there is a huge variation in what people consider to be ‘manufacturing test’), so I’m naturally thinking of ways this could have been avoided. I don’t know what kind of testing you do but in a hypothetical scenario you could have been measuring the current draw of each board to 4.5/6.5 digit precision and logging this data to a test data management/analytics system. Boards with and without bootloader may have had slightly different current draws but still within acceptable limits (or if you had really tight limits, instant failure at that point). In which case, running a capability analysis on the data would have shown a short term deviation in that particular test which would signal to someone to figure out why. The ideal solution would obviously be something that tests the presence of the bootloader directly but that is the benefit of hindsight! I don’t mind admitting I work for a software test data management company but I’m here as a Sparkfun customer, so no name dropping. Get in touch if you’re intrigued though.

  • Does anyone have any experience using the ISO 11898 (raw CAN) mode? Will it work on a 100kbit CAN bus?
