    Using the ADS1256, at a data rate of 500 SPS, and gain of 1, and MSP430 I would like to know more about the proper use of the input multiplexer to obtain data from different/distinct analog sources. Right now, I have it configured to read data from mux: 05, 15, 25 (using channels 0, 1, and 2...

    Thank you for the reply, Tom. Any examples will certainly be welcomed. Is there any header files for ads1258? [edit] p.s. My port3 is already connected with 2 other peripherals. I thought about splitting the spi line between the two and free 1 up for the A/D. But I don't want any latency issues...

    Thanks bunches Tom. And yes the 2 other ports have already taken up by peripherals. I maybe able to do some 'fancy engineering' to rewire the board, but some of the traces are in the inner layer and the pads are so small. Well, I guess there won't be much examples on bit banging a spi...

    Hello, I'm setting up my ADS1258 to MSP430F2274 connection as in figure 63 in SBAS297E. I'm kind of new to this, so I'm wondering if I can get some examples as far as configuring and r/w the ADS1258 register. Thanks for your time.

    Thank you so much for your reply. MSP430 MCLK is running at 19.2MHz. ADS1158 (slave) on SPI Interface can maximum run till 16MHz (master clock period). If I plan to run ADS1158 at 6MHz, can I use SMCLK of MSP430 to run ADS1158 or do I need another crystal oscillator to run ADS1158 independently? What...

  • Forum Post: Re: microcontroller with bluetooth module suitable for multi data acquisition system

    Bob Benjamin
    Dushyanth, To communicate to the ADS1243, you should use a micro-controller with a SPI periperal. You could also bit-bang GPIO ports, but that is a lot of extra coding that is taken care of if you have the SPI periperal. TI has a MSP430-bluetooth evaluation platform and information can be found at...

    Hi Felipe, Welcome to the e2e forum! The ADS1198 would work well with the MSP430 using a DVDD supply as low as 1.8V. For AVdd and AVss, I'm not sure that we can give you the best low-power solution without knowing more detail about your project and how you intend to use the ADS1198. There is...

    The following is my question? Can ADS1298 which was mounted on PCB be done molding process again including ADS1298 pins? I know it will affect thermal radiation. Does this process influence ADS1298 operating temperature range? Does it degrade strongly ADS1298 performance?
