  • Forum Post: Strange working of ADS1298

    Vsevolod Anisimov
    Greetings, i have a strange situation with my ADS1298. Sometimes it starts and works normally, and some times there is a trouble on DOUT line. The problem is everything else works fine, DRDY toggles with needed frequency, my FPGA after DRDY goes low generates a sequence on SPI to take data out of...

    Hi Tom, I'm sorry for missing some code. Please look at the attached files included the code , the circuit and the pin signal output. I use the internal clock in ads1298 and set the CLK pin output. When I set START=1 or set START pin High, I pick up the DRDY signal as the attached file. It seems...

    Hi Tom, You are great. Thank you, but I still meet some trouble. When I revise the code that you provided, the results in RES are shifted to the wrong positions as bellow. So I try to add another 'dummy' data, the code as follow, then I get the correct results. while (!(IFG1 &...

    bowen jing
    hi i have a question about the power-up sequence.it is written on the datasheet that "Before device power-up, all digital and analog inputs must be low."i want know why . if i don't follow this practise,what gonna happen and whether it will cause any damage to the ads1298. thanks

    hi Tom, Thank you for your reply. I followed the “initial flow at power-up”. The following is my procedure: 1. Reset 2. set the input short to get the noise ,the results are noise[] 3. set internal test signal, the results are ftest[] test[]=ftest[] -noise[]={16735511...

    Hi Tom, If I understand correctly, your saying that the internal test signal changes when you apply DC to the inputs, is that correct? ——Yes ！ That’s what happened on my board. When I do the input short, I get voltages ranging from 4.2-4.8uVpp across CH1 to CH4. You say your...

    hi , i'm using the CC2530 to control ADS1294.when set the MUX as 101 i can get the right results of internal test signal;then i simplely change the MUX as 000 and give a DC input ,i can't get the right results.why?what else should be changed?btw,when an input is added to the input pin ...

    Hi, Nowadays, we are designing an Electromyography (EMG) based device. We planned to use ADS1298 in our Project. We used the ADS1298 eval board and it s ECG-specific software as starting point. We have re-pluged a Microchip based microcontroller instead of MMB0 board. All the data connections were...

    Hi again, Hopefully someone at TI can answer this question.... We have removed the EVM board from the MMBO and attached 3.3V at TP10. The ground is attached at TP8. I have verified that 3.3V is coming across pins 2-3 on JP24. The board received here is a REV D. There have been many excellent...
