From db605dd18b11ecfb5cd9f92c721c52cb70543384 Mon Sep 17 00:00:00 2001 From: "David A. Mellis" Date: Mon, 1 Jun 2009 08:32:11 +0000 Subject: First integration of the Arduino code in Processing 5503: PreProcessor and Compiler have been integrated with changes to the Sketch. Compilation still has problems (Thread error on success, and can't handle non-pde files in a sketch). Modified the Mac OS X make.sh to copy the hardware, avr tools, and example over. Removing some of the antlr stuff. Disabling the Commander (command-line execution) for now. Added Library, LibraryManager, and Target. Added support for prefixed preferences (e.g. for boards and programmers). --- .../SimpleDigitalFirmata/SimpleDigitalFirmata.pde | 58 ++++++++++++++++++++++ 1 file changed, 58 insertions(+) create mode 100644 libraries/Firmata/examples/SimpleDigitalFirmata/SimpleDigitalFirmata.pde (limited to 'libraries/Firmata/examples/SimpleDigitalFirmata/SimpleDigitalFirmata.pde') diff --git a/libraries/Firmata/examples/SimpleDigitalFirmata/SimpleDigitalFirmata.pde b/libraries/Firmata/examples/SimpleDigitalFirmata/SimpleDigitalFirmata.pde new file mode 100644 index 0000000..1104a92 --- /dev/null +++ b/libraries/Firmata/examples/SimpleDigitalFirmata/SimpleDigitalFirmata.pde @@ -0,0 +1,58 @@ +/* Supports as many digital inputs and outputs as possible. + * + * This example code is in the public domain. + */ +#include + +byte previousPIN[2]; // PIN means PORT for input +byte previousPORT[2]; + +void outputPort(byte portNumber, byte portValue) +{ +// only send the data when it changes, otherwise you get too many messages! + if(previousPIN[portNumber] != portValue) { + Firmata.sendDigitalPort(portNumber, portValue); + previousPIN[portNumber] = portValue; + Firmata.sendDigitalPort(portNumber, portValue); + } +} + +void setPinModeCallback(byte pin, int mode) { + if(pin > 1) { // don't touch RxTx pins (0,1) + pinMode(pin, mode); + } +} + +void digitalWriteCallback(byte port, int value) +{ + byte i; + byte currentPinValue, previousPinValue; + + if(value != previousPORT[port]) { + for(i=0; i<8; i++) { + currentPinValue = (byte) value & (1 << i); + previousPinValue = previousPORT[port] & (1 << i); + if(currentPinValue != previousPinValue) { + digitalWrite(i + (port*8), currentPinValue); + } + } + previousPORT[port] = value; + } +} + +void setup() +{ + Firmata.setFirmwareVersion(0, 1); + Firmata.attach(DIGITAL_MESSAGE, digitalWriteCallback); + Firmata.attach(SET_PIN_MODE, setPinModeCallback); + Firmata.begin(); +} + +void loop() +{ + outputPort(0, PIND &~ B00000011); // pins 0-7, ignoring Rx/Tx pins (0/1) + outputPort(1, PINB); // pins 8-13 + while(Firmata.available()) { + Firmata.processInput(); + } +} -- cgit v1.2.3-18-g5258
