I am developing a SCADA system based around a Raspberry Pi host and ATMega328 remote terminal units communicating over UHF.
The state of the IO channels of each remote terminal unit is polled and stored in a file on the Raspberry Pi SD Card every second. This is read by web browsers in order to display the value over the internet.
This all works fine, except that I would expect the SD Card to fall over in a number of weeks or months based upon the wear rate of the flash.
What I need is to read and write this data to a Ram Disk.
Can anyone please advise how I can set up a Ram Disk for this distro.
Thanks in advance.
