Experiment with MSP430 FRAM board via web interface

MSP EXP430FR5739 FRAM based microcontroller board is interesting piece of hardware. It features FRAM memory instead of Flash which is claimed to withstand almost unlimited number of Reads and Writes. It is also faster. It can substitute an EEPROM on board. But it is not very popular technology due to different manufacturing. On this development board there is MSP430 microcontroller which has 16KB FRAM, 1KB of SRAM. It carries eight LEDS, MTC thermistor, 3 axis digital accelerometer, optional LDR, couple buttons. So this is great for many uses.

Even if it doesn’t have Ethernet connectivity, webui_msp430 decided to build Web UI where he could do experiments in with visual feedback. He used Linux based host where Python reads data from USB and updates data to webpage using node.js. Web interface displays analog inputs and all three accelerometer channels that are also represented in separate graphs. There is also ability to toggle any of eight LEDs from webpage.
