Import 'package:dart_periphery/dart_periphery.dart' Ĭonfig.direction = GPIOdirection.gpioDirOut The famous wiringpi library is deprecated.ĭart_periphery - all interfaces are ported:.The number of GPIO libraries/interfaces is becoming increasingly smaller. Thanks to Vanya Sergeev for his great job! Why c-periphery? # Nevertheless, dart_periphery tries to be close as possible to the original library. c-periphery is re-entrant, has no dependencies outside the standard C library and Linux, compiles into a static library for easy integration with other projects, and is MIT licensedĭart_periphery binds the c-periphery library with the help of the dart:ffi mechanism. platforms) for interfacing with external peripherals.
c-periphery is useful in embedded Linux environments (including Raspberry Pi, BeagleBone, etc. c-periphery simplifies and consolidates the native Linux APIs to these interfaces. This package is specially intended for SoCs like Raspberry Pi, NanoPi, Banana Pi et al. GPIOdirection.GPIO_DIR_OUT changed to GPIOdirection.gpioDirOut Introduction #ĭart_periphery is a Dart port of the native c-periphery libraryįor Linux Peripheral I/O (GPIO, LED, PWM, SPI, I2C, MMIO and Serial peripheral I/O).
When starting this project enums and variables from existing C und Java code were not converted to camel case.Į.g. The pi is connected directly to the Teensy board via USB cable.V0.9.x is an API change release, which fixes all the camel case warnings of the source code. I'm using this code to post messages on a LCD display board via a web service from my phone ( iPhone Safari -> Pi Web Server (OliWeb) -> cgi script -> serial write -> teensy serial read -> lcd display). SerialReader.read(serialBuffer, BUFFER_LENGTH) Then you just have to invoke the method above on Teensy with a byte array to fill with data: #define BUFFER_LENGTH 40 While (i>=0 & bufferIndex = 0 ) buffer = (char)i īuffer = 0 // Null-terminate
Read as long as there is data to be read On the Arduino side, I've created a reusable class for reading the serial port that looks like this: // SerialReader.hĬhar *read(char *buffer, int bufferSize) Ĭhar *SerialReader::read(char *buffer, int maxLength) LINE2="$($UTIL/GetProperty line2 $QUERY_STRING)" LINE1="$($UTIL/GetProperty line1 $QUERY_STRING)" with whatever you want to feed into the serial buffer. You can replace the code that says LINE1=. Here's sample code I'm using to write messages from a pi to an Arduino-compatible teensy board (which is driving an LCD display unit).
