Hi Im looking for a stand alone board to develop a data logger + data analysis instrument. Im having trouble locating a board with adequate specs. The crucial requirements: 32 bit cpu with a couple of >=14-bit >=1Msps ADCs and a couple of >=12bit >=100ksps DACs. Since I plan to do some data crunching, I need a 32bit FPU. Oh, and a nice IDE would be helpful. The only board nearing these specs is from tern.com. Does anyone have any other suggestions? Thanks for your help --------------------------------------- Posted through http://www.EmbeddedRelated.com
recommendations for a 32bit board with 16bit 1Msps ADC

Some of the ARM Cortex M4 processors might from ST Microelectronics might suit your needs. Of course with evaluation boards you might need to resolve your own analogue input signal conditioning. Take a look at <http://www.sarsen.net> for their range of digital signal processor boards. As to the IDE, what are you comfortable developing with? Close to the metal or highly abstracted? -- ******************************************************************** Paul E.

The K64F has 16bit ADC and 12 bit DAC, but not sure about the speed. The CPU is a CortexM4 with FP and DSP instruction. And is really cheap (about 35$). Bye Jack -- Yoda of Borg am I! Assimilated shall you be! Futile resistance is, hmm?

Yes, something based on the F28377D looks suitable. I will look into this further. As for an IDE, neither 'close to the metal', nor highly abstract. It wont be a big programming project, and Im happy programming in C. George --------------------------------------- Posted through http://www.EmbeddedRelated.com

Thanks Jack, I will check out the Freescale K6 and k&. I'm hoping I can find an all-in-one board I can just take out of the box and start programming (in C).

It takes something like 40 bits to be able to do FIR etc., a 64 bit FPU is fine. Either way you will have to think also about converting the 16 bit integer samples into FP and perhaps the other way around.

Their C2000 series has 14-bit/3-4Msps, and the just-released MSP432 offers 14-bit/1Msps ADCs. Both have FPUs, but you should check the specs to be sure it'll match what you want. <http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/c2000_performance/real-time_control/f2802x_f2803x_f2806x/overview.page> <http://www.ti.com/lsds/ti/microcontrollers_16-bit_32-bit/msp/low_power_performance/msp432p4x/getting_started.page?paramCriteria=no> Both can be programmed through the TI-provided Eclipse/Code Composer Studio IDE, and you can order moderately priced EVBs from TI: $13 <https://store.ti.com/msp-exp432p401r.aspx> $25 <https://store.ti.com/LAUNCHXL-F28069M-InstaSPIN-MOTION-and-InstaSPIN-FOC-enabled-C2000-Piccolo-LaunchPad-P43627.aspx> Hope this helps.

The romantic notion that all evil is a product of society has justified the release of dangerous psychopaths who promptly murdered innocent people. And the conviction that humanity could be reshaped by massive social engineering projects led to some of the greatest atrocities in history. -- Steven Pinker, Preface to "The Blank Slate" -- Frank McKenney, McKenney Associates Richmond, Virginia / (804) 320-4887 Munged E-mail: frank uscore mckenney aatt mindspring ddoott com

Not sure if you would need one of their daughterboards for the analog stuff.
