Arty FPGA Dev Kit - MicroBlaze (I2C,SPI,..)

[JrV]

Hello,

I am exploring the Arty board.

I get the a Microblaze Base  system up and running and like to start programming the system, more specific

- the I2C (SCL/SDA)  (HIH6130 sensor) 

- SPI pin (TLC5947).

- Build IP block written in VHDL (PWM driver).

 

 

Any starting points are welcome.

 

Regards,

J.

Hi J,

I would look here for the different IP cores that we have. You can use specific Pmods IP cores that use i2c or spi like the PmodAD1 and PmodAD2 here and change what you need to make your devices work. Here is a link to the Arty resource page that has demos and tutorials with microblaze designs. Hope this helps!

thank you,

Jon

Hello,

What about direct use of the I2C pin SCL/SDA on the expansion header/ Arduino/chipKIT shield connectors.

There's a really popular core on OpenCores for handling I2C interfaces.  You can find it here.  It should help you with any "direct use of the I2C pin SCL/SDA on the expansion header".

Hi J,
 

Here is a link to the PmodAD2 that has a project done in ise with the nexys3 in VHDL that had I2C communication with the PmodAD2. You can look at the I2C VHDL code to help you with your code if you are trying to do this in VHDL.

cheers,

Jon
