We are looking for freelancer with experience in some Ethernet Module / WiFi Module to help write a Library to access a FireBird Database each minute and sincronize data with Ethernet Module. This module need enough memory to keep up to 1Mb of data. One microcontroller will request information by UART TTL from the Module by simple ASC Protocol. Even if the network, server or database has stopped, the microcontroller will check the last update from the Module Memory. Also the microcontroller will send information to the Module by UART TTL, and the Module need update the Firebird Database. This system need to be cheap, stable, to be installed in some machines that can't stop work even that haven't communication with the database.
