There is interesting point in one datasheet i have downloaded before i found this repo. [https://www.tme.eu/Document/746174d0ddac05c785c5271afce6c05c/RS0010.pdf](url) On page 43 it says: > Repeated procedures for an 4-bit bus interface Noise...
Thank you Will that approach work on hdmi between tv and settop box?
david, thanks. I am waking Teensy by ERR output from TJA1055. That pin indicates start of frame on bus. My sketch is based on bi directional forward example of FlexCAN...
Many thanks. Maybe if i call detachInterrupt on those two pins, it might help. Then reattach it before entering sleep.
I am using Arduino 1.8.9 and Teensyduino 1.5.3
Seems like this approach helped: digital.pinMode(TJA_MASTER_ERR, INPUT, FALLING); digital.pinMode(IN_DEBUG, INPUT_PULLUP, FALLING); Snooze.deepSleep(config_teensy40); detachInterrupt(digitalPinToInterrupt(TJA_MASTER_ERR)); detachInterrupt(digitalPinToInterrupt(IN_DEBUG));
Sure, i will draw the schema in KiCad and share then. I have been using in past MCP2551, but that one, as part of high speed can group, has different...
Yes, that is the only drawback of TJA, but i need it for my infotainment project in my Peugeot. Had been using that MCP2551, but only as listen only mode...
Well, i used other approach. My system was supposed to store to eeprom several variables, but as mentioned, after waking it up from sleep, the eeprom writes hung the Teensy...
