I just thought I'd try Jim's OneWire library and got the following errors when the Arduino environment (11) starts up:
OneWire.cpp: In constructor 'OneWire::OneWire(uint8_t)':
OneWire.cpp:74: error: 'digital_pin_to_port' was not declared in this scope
OneWire.cpp:76: error: 'port_to_output' was not declared in this scope
OneWire.cpp:77: error: 'port_to_input' was not declared in this scope
OneWire.cpp:78: error: 'port_to_mode' was not declared in this scope
OneWire.cpp and OneWire.h are in hardware/libraries/OneWire
Any ideas what went wrong?
