Part Number: ADS7046


Hello,

Does TI offer example C code for the ADS7046 or any other for acquiring 3msps sampling?

    Hi db,

    We do not have any example code to share with you.  The ADS7046 uses SPI mode 1, its a straight forward 3-wire SPI interface.

    hi tom,

    Thanks for reply. I'm working on same and i also get result but I trying to get precise sampling rate.

    Below I attach some snap for SCLK and CS signal. i trying to minimize time between sclk regenerate pulses. it is taking long time so I can't be able to reach sampling rate. I trying with different methods like Interrupt, DMA but same got. so can you suggest possible method to acquiring max 3msps sampling rate using stm32h745.  

    Red= CS signal, Blue= SCLK.... controller SYS clock frequency 400Mhz

    Unfortunately we don't know enough about your controller to tell you how to speed things up.
