TI中文支持网Part Number:ADS1298
Hello, I am using the ADS1298 to acquire signals, but I am encountering an issue. I am generating a 1 Hz sine wave with a signal generator and feeding it into channel 1 of the ADS1298.
I am using an STM32 to communicate with the ADS1298, and I have set the ADS1298 sampling rate to 500 SPS. I am instructing the ADS1298 to sample 500 points and then stop. However, on my host computer, I see multiple cycles within one second. I have not yet found the reason for this issue. The DRDY pin pulses are displayed on the oscilloscope as shown in the figure.
The raw data received by STM32 during the next acquisition is as follows:
