I2C read of De0 nano accelerometer

Hello everyone, I am using de0 nano and would like to try I2C read of accelerometer(ADXL345) that embedded in de0 nano. So I take it that I2C read has the following sequence: 1) generate start...

Hello sindredit,

well, as you can see at the title, the purpose is to read the data value of registers inside the ADXL345 (accelerometer) using I2C protocol.

The problem I encountered were (therefore I asked this question in this thread)

1. I was new in FPGA and not familiar with I2C communication protocol

2. I was not able to find the "right" timing diagram to communicate with the ADXL

Now by reading this thread, you could just use the I2C timing diagram.

It should be noted that it is all about I2C read and write to interface with the ADXL.

I recommend you to start by learning the I2C protocol before starting with the ADXL interfacing.

Cheers,
