Thanks lot for your helps, ysc. It will take over us, that is too long for my application. I really appreciate your helps, ysc. Tuesday, July 28, 8: Somebody shoot me if has 16 chip selects. Monday, July 27, 6:

I need your suggest on my project. Thanks lot for all the suggestions from this group.
I really appreciate your helps, ysc. The CS sholud keep low during conversion and data transfer. On Tuesday 28 July Your AD converters are capable of shifting data to each other. Protecting the IoT with Invisible Keys.
Arduino Robotics Lonnie Honeycutt. Hi, It seems that you would like to synchronize your 16 ADCs. So it will never be able to sample multiple inputs at one time. Do you need to synchronize all the ADCs? I need to syncronize all the ADCs.
Simple SPI driver for AT91SAM
Thanks lot for your helps, ysc. Hi, What is your expected rate? May be with a little FPGA. As you do not tell us which ADC you are using, I suggest you 2 possibilities: This process takes about 50us.
About at91sam SPI CS question when using PDC – Welcome to AT91SAM Community Discussions
If that is not the case then I wonder if your evalutation kit has a decoder for CS pins. If this is the case then: The 2 case may apply on my project.
You need to take into account the exact SPI clock frequency and processing time. As you mentioned, kps will be splitted by 16 channels, it will be: Monday, July 27, 6: I’m sure AD has better offerings for these kind of applications. xpi
need help on SPI
If you need multiple inputs to sample simultaneously, you need either multiple sample and hold buffers or multiple ADCs.
Create free sspi Forgot password? Use of PDC is optional but definitely useful. Sign in Sign in Remember me Forgot username or password? Hi Caglar, Just a comment about your post. Can PDC be a help? Tuesday, July 28, 8: Spl fast enough for my project. Theorically, you need 3 bytes at a maximum SPI clock of 2. For single ADC, I can communicate with it as following order: Ideally, all ADCs should be samples at the same time although the data can be transferred in serial order.
