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… Continue reading

Texas Instruments enters hobby market with cheap dev platform

There is quite a buzz these days about this development board. This is probably because of many cons and pros about it. But probably this is really good thing that TI company decided to make prototyping possible for everyone. We all know that MSP430 microcontroller has recommended their place due its low power consumption and this is why it is frequently found on various multimeters. Anyway you can get a simple prototyping board only for $4.30 which includes DIP socket for MSP430 microcontroller with 2kB Flash, 128B of RAM, 10 GPIO, 1x 16-bit timer and more features. LaunchPad also has a mini-USB connector along with flash emulation circuitry that allows live flashing an emulation of projects. Also there are two programmable LEDs and buttons. I’d say this is great value… Continue reading
