Arduino mega 2560 pin conflicts4/8/2024 That includes other pin-change interrupts, clock/timer interrupts, external interrupts, and every other type of processor interrupt. See the notes under Variants and Branches below for advice in using this library in combination with such libraries.Īnother non-trivial, but hidden limitation is that all interrupts are disabled during most of the transmission of each character, which can interfere with other processes. Some other libraries using pin change interrupts include SoftwareSerial, NeoSWSerial, EnableInterrupt, PinChangeInt, Servo, and quite a number of other libraries. You will be unable to compile them together. The most obvious "limitation" is that this library will conflict with all other libraries that make use of pin change interrupts. It was further modified to use a timer to improve read stability and decrease the amount of time universal interrupts are disabled using logic from NeoSWSerial. This library was developed from the SoftwareSerial library that is a built-in standard Arduino library. Try running our Example sketches with your Arduino board and SDI-12 sensor.įull details on the library functionality can be found on github pages: https:/ / / Arduino-SDI-12/ Origins and Inherited Limitations Variants and Branches we created to overcome some limitations.Renaming NoticeĪs of version 2.0.0 this library was renamed from "Arduino-SDI-12" to simply "SDI-12" to comply with requirements for inclusion in the 's IDE and Library Manager. This work is motivated by the EnviroDIY community vision to create an open source hardware and software stack to deliver near real time environmental data from wireless sensor networks, such as the Arduino-compatible EnviroDIY™ Mayfly Data Logger. Advantages of SDI-12 include the ability to use a single available data channel for many sensors. SDI-12 is an asynchronous, ASCII, serial communications protocol that was developed for intelligent sensory instruments that typically monitor environmental data. It provides a general software solution, without requiring any additional hardware, to implement the SDI-12 communication protocol between an Arduino-based data logger and SDI-12-enabled sensors. This is an Arduino library for SDI-12 communication with a wide variety of environmental sensors.
