how to add i2c on MicroBlaze EDK

hello
I need your help I want to connect a gyrocompas(HMC5883L) with a microblaze which is done by I2c and as microblaze does not have the bus I2c. I must add it as a peripheral to the microblaze but I do not know how in EDK
regards

Re: how to add i2c on MicroBlaze EDK

In case your your gyrocompas(HMC5883L) has a I2C and the microblaze does not, then you need to do a bus protocol conversion. A traditional way to do this is to use a protocol conversion bridge. So if your microblaze is using ABC protocol, then you need to design a ABC-to-I2C bridge and add it to the Microblaze.

It's definitely dated as the current MicroBlaze default bus protocol is AXI4 in ISE 14.7.

You can also look at Xilinx document UG682: https://www.xilinx.com/support/documentation/sw_manuals/xilinx14_7/edk_ctt.pdf
Take a look at Chapter 6 on page 45.

hello
Someone has already work on the code for the conncetion of gyrocompass HMC5883L with MicroBlaze in 3AN FPGA
