FAST 3ch 16-bit ADC recorder 32GByte media - open to bidding

Hi there, I am an electrical engineer, I want to go through your requirements , Kindly send me a private chat message. This is wrf FAST 3ch 16-bit ADC recorder 32GByte media

Hello, have a great day. We will fabricate and ship the Hardware. it will be based on ARM microcontroller. Please feel free to contact us. Best Regards, Shahbaz.

3 channel 16 bit ADC recording. Can we use Raspberry Pi for this project, because it readily has SD card interface and Ethernet interface through which data can be transferred to PC. We can design an addon card to raspberry Pi with a 24 bit ADC like ADS1298 and extract MSB 16 bits out of it and deliver to raspberry pi or we can use a 16 bit ADC (TI or Analog devices) Can we discuss further details?

Have had recent experience with very similar project with 8 channels, can provide full design for your project

Hello, I am interested to work on this project. From description is not quite clear if you need max 400kHz of ADC conversion rate or you need to read sine wave with max frequency of 400kHz, in this case ADC conversion rate should be much higher. For fast ADC it might be possible to use FPGA development board fitted with custom SD card reader and converters. If 400kHz ADC conversion rate is OK, it should be possible to use fast micro controller to get readings from ADC ICs and save data on SD card. Send me a message me to discuss further requirements.

Sounds really interesting. You'll need to write a few megabytes of data per second and capture at a rate of 1.2 MHz too. An atmega328p can handle that but I suggest not using Arduino but programming directly. For an ADC there is a plethora of options out there, how many bits of accuracy do you need? I am an electronics expert and an avid programmer. Pl. let me know if you have any questions.

You could use Arduino Due which can reach the clock speed of its I2C upto 400 kHz. So, simply read the data from analog pin and store on SDCard as well.

I have a PhD in electrical engineering with several years of experience in designing various analog and digital circuits. I can definitely help you get your project done completely and will provide you with a very well written report. Thank

My proposal is to make a design with the standard CHIPKIT MAX32 Board from National Instruments. It can read analog channels directly. I think is the better option for a single or low units prototype. Files could be accessed by FTP with an ethernet interface, they also cane stored in a SD Card un FAT32 to be read from a computer. If you want to make a board for large series I can make you a custom board. We can discuss it at the chat.
