Next step beyond MSP430 LaunchPad ( MSP430G2553 )

Started by spacejuggernaut June 15, 2012
I've been using the MSP430G2553 LaunchPad for a number of projects, but realized I ran out of IO ports.

Future projects:
6 digit 7 Segment display
with up to 8 interrupts and 2 timers
Probably 32 IO ports.
4 ADC ports

Also need to be able to prototype beyond the evaluation boards

Any suggestions as to the next level evaluation board and processor,
There's just too many to choice from.

Beginning Microcontrollers with the MSP430

What about the MSP-EXP430FR5739 Experimenter Board?

It has 32 I/Os, 16Ch 10-Bit ADC12, 8 Display LED's, 3 axis accelerometer, NTC Thermistor, 2 User input Switches, and more, only 25 bucks more than the LaunchPad, but amazing new FRAM technology.

And, to make your project really easy going, you can load CamelForth for interactive programming.

Hello Dirk

That's it,

I didn't know the MSP-EXP430FR5739 Experimenter Board existed, when I
checked out TI's EStore I only saw the

MSP430FG4618/F2013 Experimenter for $99 and MSP430F5438 Experimenter Board
for $149 that require the Flash Emulation Tool

I don't require the LED's, I can remove these to prevent added load, Also
thanks for Camel Forth, Didn't know about this.

I tend to program in assembler, it provides better access to the ports and
especially the interrupts.

Right now I'm working on a humidity controller for the furnace A temp probe
outside and the built in temp probe to determine temp differential, then to
a servo connected to the humidistat to regulate the humidity in the house,
this will be the final destination for the MSP430g2553.

The new board FR5739, will be used for a mutli lighting system, controlled
by 3 audio filters, the output rectified to produce pulses according to
frequency and duration, the longer the pulse the more lights will come on,
basically it's a glorified colour organ controlling 12 to 24 lights or
strobes. Also debating to use a DSP with FFT in place of the Audio filters
using opamps.

Again

Thanks for your help

Just ordered the board

Regards

Roman

Rather than mess with a DSP why not a simple set of bandpass IIR filters
on the micro executed in software? The old 1 series could handle 12 of
these at 8000 samples a second. the FR series has a 32 bit multiplier on
board so should deal with it better. Also by careful planning of the
code you can run the FRAM parts at close to their nominal maximum 24MHz
clock speed. use integer maths on the filters for speed.

use an 16x I/O expander on I2C or SPI.

If you want to stay with something familiar, you can get the 2553 in
SO form factor with an additional 8 I/O Pins.

Shift registers are pretty cheap (about 25 cents) and they are an easy
way to add dedicated input and output ports. There are GPIO
(tri-state) expanders, but they are practically as expensive as the
2553 itself, so if you need tri-state you really are better off with a
bigger chip.
