The problem is that these - are variables local to the TwoWire object, and by the time we actually have read the - data, and know what the length actually is, we have no simple access to the object's - variables. The actual bytes read *is* given to the callback function, though. - - The ISR code for a slave receiver is commented out. I don't have that setup, and can't - verify it at this time. Save it for 2.0! - - The handling of the read and write processes here is much like in the demo sketch code: - the process is broken down into sequential functions, where each registers the next as a - callback, essentially. - - For example, for the Read process, twi_read00 just returns if TWI is not yet in a - ready state. When there's another interrupt, and the interface *is* ready, then it - sets up the read, starts it, and registers twi_read01 as the function to call after - the *next* interrupt. twi_read01, then, just returns if the interface is still in a - "reading" state. When the reading is done, it copies the information to the buffer, - cleans up, and calls the user-requested callback function with the actual number of - bytes read. - - The writing is similar. - - Questions, comments and problems can go to Gene@Telobot.com. - - Thumbs Up! - Gene Knight - - */ - - uint8_t TwoWire::rxBuffer[NBWIRE_BUFFER_LENGTH];
