VHDl spi adc example

[Tex]

Hello,

i'm learning about spi with altera max 10 using 24 bit adc..

previously i got few examples from few people of the forum but they are very complex to learn..

also please suggest me any course on vhdl to learn.. 

@ShengN_Intel 

@FvM 

please try to help me.. 

Best regards,

Hi Tex,

FYI that currently we don't have exact example design for 24-bit adc as Intel's board mostly in-built with 12-bit adc.

May be can try to get the example design from the vendor of 24-bit adc.

Thanks,

Regards,

Sheng

hi sheng,

Okay, apart from 24-bit or anything i want to learn spi communication in VHDL using any adc..

please share any tutorials or codes to learn with altera max 10..

Best regards,

Tex

Hi Tex,

Max 10 ADC are line-in ADC. Usually Modular ADC Core IP is used for that. Check these two links http://gogofpga.blog.fc2.com/blog-entry-182.html and https://www.youtube.com/watch?v=0oO1RFa-4Xk&t=1s

The SPI RTL design example can be found had been shared to you before. Can't find any VHDL one. Btw, the design store example design https://www.intel.com/content/www/us/en/design-example/715016/max-10-serial-peripheral-interface-master-an-485.html I had been tested on DE-10 Standard (Cyclone V) ADC since Max 10 ADC are line-in ADC. Check the attached design folder and STP waveform. The function as below:

Control Register Write: CS high, WR high

Transmit through MOSI: CS high, WR high, addr "10"

Status Register Read: CS high, RD high, addr "01"

Received (MISO) to data_bus: CS high, RD high, addr "11"

Thanks,

Best Regards,
