Re: Porting from MOD5272 to MOD5270

Hi Tom, thanks for the quick reply! My long term plan is to migrate to the MOD5441X. I actually have a dev-kit here, and a redesigned board to test it on, but I've been having a really tough time porting to that. It's so much more capable; I've been having a tough go figuring out how to map the inte...

Porting from MOD5272 to MOD5270

Is there any kind of article available that talks about porting a project from the 5272 to the 5270? I mean, I know the obvious speed difference, but does anyone have experience doing this, and can you tell me how hard it was for you? Thank you, Dan Brunermer

Re: Multiple calls of OSSemInit()

It's a MOD5272. Not that it matters, though, as the high-voltage section just committed suicide. And the other question - they are external IRQs, INT3(DataDone) and INT5(FireDone).
Thanks - Dan B.

Re: Multiple calls of OSSemInit()

pbreed - Here are the setups. The interrupts are firing. I see the '|' character streaming from the serial port, it's just that the task waiting on that post never releases. And the whole reason I chose 'putchar' was because it was one of the few functions not on the forbidden list in the manual (P1...

Re: Multiple calls of OSSemInit()

So I'm really not making any headway here. I worked on the suggestions last night, tried it this morning, and it's not getting better. Let me show some code; MOD5272 platform. Here are what I think are the relevant snippets from the various things: OS_SEM g_datasem; // These are in the declarations ...

Re: Multiple calls of OSSemInit()

The docs and manuals don't seem to talk much about priority directly, so I guess I can only assume that they aren't a player here. I mean, the source code in ucos.c, which I will freely admit I do not understand at all, makes a bunch of references to something that looks like priority. These two lin...

Re: Multiple calls of OSSemInit()

So I did what you said and looked at the UCOS.C file. It looks like in the case I was hoping to prevent it would fail anyway. But, looking at the other functions, I have a new question. What is / How can I find out more about the interplay of Semaphores and Task Priorities? Can I have more than one ...

Re: Multiple calls of OSSemInit()

As a follow-up question, I understand you should only need to initialize the semaphore once, but can you call OSSemInit more than once on the same signal? I have a case where I think I'm going to have one extra Post, and I'd like to clear it before I restart my sequence. Is that OK, or does it funda...

Endianess Question

Hey all, I'm sorry but I have a big-endian question or concern that I can't seem to wrap my head around. (MOD 5272) I have this CPLD that I originally designed as an 8-bit accessible device, and endianess wasn't such a big deal, because I could talk to the thing a byte at a time anyway, so it was fi...

Re: Spontaneous Reset after Setting Bit on IO Port

Sorry I didn't get back sooner, I was off work for a couple days. Back Problems. Age sucks. Anyway. I decided to try the staking the relay high off the board on wire-wrap socket pins, even the load. The first time I engaged the relay, it worked perfectly, and I got excited. Unfortunately, it only wo...
