HOW TO USE THE XINTF OF 28335 FOR EXTERNAL parallel AD

Other Parts Discussed in Thread: CONTROLSUITE

Hi,

I am pretty new with this implementation. In my case, I want to use XINTF on 28335 to work with an parallel 12 bit ADC chip which will be use for about 20MHz. First, I want to achieve the basic read operation.

What should I do? I have readed the reference guide of XINTF. But I do not quite get it. Can you guys give me a detailed application notes, or just try to give me some information?

It bothers me for days.

Thanks very much.

Hi,

Did you check with the example available in controlSuite? As for the documentation, the doc that you've already read is the only doc available.

Also, check this link out:

Hi ,

Thank you very much for that link.I am presently working with TMS320F28335 just a few days. This file helped a little bit. The main goal is to connect the ezdsp and the ti ADC12040 or ADS5231 via XINTF.I will use the parallel 12 bit ADC chip for about 20MHz,but i have no idea how to solve the problem how to write the time series code of the AD's pin PD,OE and CLK. The clk use a clock with low jitter and fast rise and fall times (<2ns).I don't know whether the 28335 can fit it.And can i set the PD and OE to GND(low level).
