Method isPidSupported

src/ELMduino.cpp:3242–3276

bool ELM327::isPidSupported(uint8_t pid) Description: ------------ * Checks if a particular PID is supported by the connected ECU. * This is a convenience method that selects the correct supportedPIDS_xx_xx() query and parses the bit-encoded result, returning a simple Boolean value indicating PID support from the ECU. Inputs: ------- * uint8_t pid - the PID to check for

  * bool - Whether or not the queried PID is supported by the ECU.
