Access to other chip features such as on-chip temperature measurement, analog-digital converter, transmitter power control etc is also provided. RH_RF24 Works with Silicon Labs Si4460/4461/4463/4464 family of transceivers chip, and the equivalent HopeRF RF24/26/27 family of chips and the HopeRF RFM24W/26W/27W modules.RH_RF22 Works with Hope-RF RF22B and RF23B based transceivers, and compatible chips and modules, including the RFM22B transceiver module such as hthis bare module: and this shield: and this board: and RF23BP modules such as: Supports GFSK, FSK and OOK.In some specialised use cases, it is possible to instantiate more than one Driver and more than one Manager.Ī range of different common embedded microprocessor platforms are supported, allowing your project to run on your choice of processor.Įxample programs are included to show the main modes of use. ![]() It is also possible to use a Driver on its own, without a Manager, although this only allows unaddressed, unreliable transport via the Driver's facilities. Thereafter the facilities of the Manager can be used to send and receive messages. The programmer is required to instantiate a Driver and a Manager, and to initialise the Manager. Managers provide high level message sending and receiving facilities for a range of different requirements.Įvery RadioHead program will have an instance of a Driver to provide access to the data radio or transport, and usually a Manager that uses that driver to send and receive messages for the application.Drivers provide low level access to a range of different packet radios and other packetized message transports.RadioHead consists of 2 main sets of classes: Drivers and Managers. If you are a beginner, you will need to spend some time gaining knowledge in these areas first. It may not be an appropriate project for beginners. Before asking a question or reporting a bug, please readĬaution: Developing this type of software and using data radios successfully is challenging and requires a substantial knowledge base in software and radio and data transmission technologies and theory. Do not contact the author directly, unless it is to discuss commercial licensing.

The version of the package that this documentation refers to can be downloaded from You can find the latest version of the documentation at It provides a complete object-oriented library for sending and receiving packetized messages via a variety of common data radios and other transports on a range of embedded microprocessors. Not bad for a couple of nuggets short of a cheeky tenner.This is the RadioHead Packet Radio library for embedded microprocessors. It offers the convenience of a micro-USB connection for both power and data ( running at 3.3V), and despite its size has built-in WiFi and 4MB of flash memory. A bit like dating.Īfter some light research, I discovered that the Wemos D1 Mini is an Arduino compatible ESP8266(EX)-based board, busting out 11 digital input/output pins and a single analog input pin. What’s a Wemos D1 Mini?īefore we start touching this thing, we should probably get to know it first. If you’re not fussed about waiting a month+ for delivery, China stores like AliExpress will have plenty. The newer V3 is available at RasPiO (this is where I purchased mine) The older V1 board is available at Amazon. I wasn’t sure what it was, but for £8 I didn’t really care ( “gear whore gear whore!”).Īnyway, new board = new territory, so I had to learn how to get this thing running. I bought one back in December as yet another unnecessary purchase (my last post was about another!). ![]() ![]() The D1 Mini has a really simple setup and uses development environments and code languages that should be familiar to any Arduino user. I know a lot of these new/different boards can intimidate us average makers, but this one sits on the ‘not scary’ list. ![]() If you own an Arduino but haven’t bought yourself a Wemos D1 Mini yet – you should.
