How do I use ELM327 with SAE j1978?
If you need to follow the SAE J1978 order, you should send the ELM327 an AT SS command first, or step through each protocol with the TP command. The automatic search works well with OBDII systems, but may not be what you need if you are experimenting.
What is the output voltage of the J1850 PWM pin?
The pin normally outputs a logic high level when a nominal 8V is required (for J1850 VPW), and a low level for 5V (for J1850 PWM), but this can be changed with PP 12. If this switching capability is not required for your application, this output can be left open-circuited.
How does pp 0E work with ELM327?
If bit 7 of PP 0E is a ‘1’ (the default), this pin will function as a Power Control output. The normal state of the pin will be as set by PP 0E bit 6, and the pin will remain in that state until the ELM327 switches to the Low Power mode of operation, when the output changes to the opposite level.
Does the ELM327 IC display the J1850 CRC code?
The current version of this IC does not display the CAN CRC code, nor the special J1850 IFR bytes (which some protocols use to acknowledge receipt of a message). I [ Identify yourself ] Issuing this command causes the chip to identify itself, by printing the startup product ID string (currently ‘ELM327 v2.2’).
