RFM69 C++ driver library for STM32 (and other controllers)

I recently developed a protocol agnostic driver library for HopeRF’s RFM69 modules. Protocol agnostic means that you get full control over the module and the data packets that you want to send or receive. You can use this library for receiving packets from existing commercial devices like temperature sensors, or you can set up your own RF network using your own protocol.


Connecting an external RAM to a microcontroller the easy way through pin swapping

In some applications you need greater amounts of RAM. Microcontrollers like the STM32 only have around 20 to some hundred kilobytes of internal RAM. So what do you do if your application needs require some megabytes of RAM, for example in high speed data acquisition systems?
