Read Parallel CMOS ADC using Nucleo-H743ZI2 dcmi

HI there I am do a continues read an of ADC a parallel binary data https://datasheets.maximintegrated.com/en/ds/MAX2771.pdf at the speed from 4-16MSPS with nucleo-H743ZI2. The binary data is sent through 2 ADCs where each has a specific channel I(I0,I1) and channel 2(Q0,Q1),and all are clocked with ...

Re: Receive a 4MSPS CMOS parallel ADC binary using nucleo-H743ZI2 on Arduino

look up the datasheet. it looks to be some sorts of a spi device. fasters ways to read it include: 1. use the spi module on your chip, via polling; 2. use the spi module on your chip, via interrupt; 3. use the spi module on your chip, via dma; ... unfortunately the SPI is only used to program the b...

Re: Save Sampled data to my pc

USB full speed is normally 12 M bits per sec, that's the bandwidth, and normally with all the multiplexing between the keyboard, mouse and other peripherals, the host does all the polling and allocate slots, it is at best a few m(bits)ps. so that in itself is a bottleneck, the connection between st...

Save Sampled data to my pc

HI there I am trying to read an ADC a parallel binary data https://datasheets.maximintegrated.com/ ... AX2771.pdf at the speed of 4MSPS with nucleo-H743ZI2. The data is sent with from 2 bins (I0,I1), CLK_out and GNS pin, my main goal is to read the data then save into a file. //#define CLK_OUT PC0 /...
