Re: XU208 questions about port usage

Glad to have your insight on it, thank you. I'm confident I have the code working now. Q: Any special reason that you are using the TQFP128 pin package over the recommended 64 pin TQFP package of the XU208? Do you need the extra ports for your widget? I'm using the XU208-128-TQ64 as recommended, usi...

Re: XU208 questions about port usage

Hi mon2, Yeah, that's the project I've downloaded and am importing my changes into. In their code they do not use _4F and just leave it alone as a part of _16B, so I can't be sure that the ports that would overlap with _4F aren't required for operation. I used the XHRA-2HPA's limited customizability...

Re: XU208 questions about port usage

Thanks for your detailed response. Hello and welcome. Let me try to answer some, not all, of your questions. From a quick glance, do not see that port P1L0 is overlapping the 16B port . You're totally right, I overlooked it Check this document: https://www.xmos.com/published/xmos-programming-guide?v...

XU208 questions about port usage

Hi, I honestly don't have much previous C++ or xcore programming experience so everything is somewhat new to me, my bad if I ask a stupid question :) Anyways, since the discontinuing of the XHRA-2HPA I've been working with the project to migrate this to a XU208-128-TQ64 and I feel like I'm getting c...

Re: XHRA-2HPA-TQ64 - Maximum acceptable current pull from single GPIO pin?

I searched for GPIO in the data sheet, so that's why it didn't show up haha

Thanks!

XHRA-2HPA-TQ64 - Maximum acceptable current pull from single GPIO pin?

Another day another question,

How much current would be considered "safe" to pull from a single GPIO pin?

Right now I would be at about 15mA with my implementation but I'm scared this might be a bit too much, the datasheet tells me nothing.

What do you think? Ok or nah?

Kind regards,

No problem, it happens

Thanks though

Re: XHRA-2HPA-TQ64 - Events for GPI pins? How to use them even?

I don't think the XHRA-2HPA supports running self compiled code, only its encrypted firmware with a modifiable configuration.

I could be wrong though?

Anyone? Maybe I missed something but I can't seem to find any additional information on it in the datasheet

XHRA-2HPA-TQ64 - Events for GPI pins? How to use them even?

I feel like I'm overlooking something, but how do I actually make use of the GPI pins? In my case I want to have a event where if GPI7 becomes high or low I can send some I2C commands. As GPI6/7 are not used by the HID feature, there should be a way to use them right? I don't understand why they're ...
