Kerry wrote in to let us know about his adventure in boot strap loading[BSL] his Launchpad to program his MSP430F5172 development board. Since he did not have a JTAG on hand and the MSP430F5172 does not support SBW programming**, he planned to use the Launchpad as a BSL. Fortunately, most of the MSP430 devices can be programmed using the built-in BSL...

oPossum has written a detailed tutorial on converting the internal temperature ADC reading to useful values, along with code: TI has some sample code for the internal temperature sensor(SLAU144), but it does not explain how to scale the ADC reading to useful units of degrees. Here is a step-by-step explanation of how to do the scaling with integer math for...

XPG has been working hard to develop a plugin for MSP430-gcc and MSPDebug… and it looks like he’s come to a workable solution. He’s made sure it works with the latest version of Eclipse Indigo. If installing from source or the command line intimidates you, then this is a perfect method to install an open source development environment for the...
