- In MSP430 Value Line LaunchPad Development Tool, there are:
- 10 GPIO in a 14-pin MCU
- 16 GPIO in a 20-pin MCU
- GPIO = General Port Input Output
- What are you programing? The microcontroller (MCU)
INPUT –> MCU –> OUTPUT
- MSP430G2211/MSP430G2231/MSP430G2452/MSP430G2553 is some common microcontroller chips used. MSP430G2553 is the best in term of FLASH and RAM size.
- The MSP430 will run with anywhere between 1.8 V and 3.6 V, though at least 2.2 V is needed to do any programming to the chip. Keep in mind that the speed at which the chip is able to run also depends on the voltage; though it’s capable of running up to 16 MHz, at 1.8 V an MSP430 cannot run any faster than 6 MHz.
SOFTWARE TO PROGRAM MSP430 LAUNCHPAD:
- IAR Embedded Workbench Kickstart
- The free version is limited to 4 kb code size
- Another possibility is a 30-day Evaluation version that has no limitation.
- Code Composer Studio
- TI’s own MSP430 development suite.
- Free version is limited to 16 kb code size.
- Easy to use. Arduino-compatible.
Normally I will use Code Composer Studio (CCS) since the software is very powerful, and equipped with tools to troubleshoot the codes. If you prefer something simpler, you may use Energia.
