Imagine being able to prototype your entire signal chain - input signal conditioning, A/D conversion, processor, D/A conversion, and output signal conditioning - with simple building blocks. Imagine not having to lay out a printed circuit board just to evaluate a system signal processing idea.
With TI’s modular evaluation modules (EVMs), you can put together a complete data acquisition system featuring signal conditioning, A/D converter, and a processor, all in just a few minutes. And you can add on from there - a D/A converter, or more output signal conditioning. The modular EVM boards go together easily thanks to standardized connectors, so you can quickly build a complete hardware prototype, and get to writing your application code faster.
You can also build your own modules to fit this system, to accomodate circuits that may not be available directly from TI. Just follow the guidelines listed below.
Modular EVM Resources
A processor is the heart of your system. Do you need the power of a DSP, or the features of a microcontroller? You’re free to choose and explore these options with the modular EVM system. The signal chain building blocks have the ability to easily snap into place on an interface card to connect them to most of TI’s DSPs.
Don’t need a DSP? TI’s MSP430 microcontroller products and MicroSystem Controllers feature analog functionality built-in. In many systems, external data conversion components may be needed to complement the built-in functions. For those cases, our broad range of data conversion products can be used with these microcontrollers.
Using FPGAs instead of a processor? Some distributors of FPGAs have developed interface boards that allow the signal chain building blocks to connect to their FPGA development systems.
If you just want to evaluate the device on the EVM using standard lab equipment, or want to try wiring the board into your existing system, the modular EVMs will allow for that as well, no processor needed. You have access to all the essential interface pins on the device through the standardized connectors. So no matter how you process the data, we’ve got a way to help you develop your system.
Developing software with the modular EVMs is easy. If you’re using a DSP, our free Data Converter Plug-In for Code Composer Studio can help you set up the DSP to interface with the data converters.
If you’re developing MSP430 code with Softbaugh’s HPA449, you can use any of Softbaugh’s tools to download programs to the MSP430’s flash. The HPA449 board also has the ability to program the flash through the serial port. Use this open-source SimpleFlash program to download your hex code to the HPA449’s MSP430F449 processor.
Code for use with the modular EVMs on the different platforms can be found in the tool folder for the EVM. Look for the Related Software section in Related Documents in the tool folder. Very often, this code is a simple project that runs on the processor used; in some cases, complete software to evaluate data converters that runs on your PC is included as well.
