The datasheet I read did say 3.3v compatible, https://www.nxp.com/docs/en/data-sheet/TJA1050.pdf "Input levels compatible with 3.3 V and 5 V devices". I think it may be either, no CAN is 3.3v compatable, or just none of these Chinese transcievers. Anyway I have some progress, I put the...

No luck with the TJA1050, the esp32 reads nothing from it while atleast the vp230 can recieve. I plugged the VP230 back in and programmed the CAN Reciever example, which comes with the lib. With logic analyser I can see the r4850g2 is sending constant packets, but the esp32 will only pick up...

It could be but the package and etching look good. I poked it with the meter, its showing 30k R to ground on pin 8, which puts it in slope control mode. I couldnt measure any voltage on pin 5 Vref, it should be half Vcc. It was this...

I am having some problems with CAN. The ESP32 seems to crash whenever commands are sent, I have tried bauld at 125E and 250E. I hooked up a ssd1306 screen with a running count so I can see when it crashes. With debug turned on I get some data out 17:59:31.770 -> Starting CAN 125E3 success...

I have a couple of Greenworks tools but no battery. It would be great to know what signal is used for the enable pin from the battery, so I can use my lipo packs with it. Without this signal it spins up, then turns off after 1 second. Other tools its common to have a 10k NTC resistor to...
