Essentially, Libstock is a crowdsourcing model. What perhaps could help is some coordination, for example, we don't need another robotics project as much as support files for more processors. ME needs to focus on the things that can't be addressed by Libstock; such as adding MZ support to the PIC32 ...

Execution from RAM isn't possible in a PIC24/dsPIC. It's only possible in PIC32, which is a modified von Neumann architecture.

That was fast.

If you haven't noticed, there's a new wifi chip from China that's creating quite a stir. It's cheap, has 100 mw of power, and responds to AT commands. But there's more. The chip is a configurable core ARM, which means that people are hacking it to be a complete wifi ARM system on one chip. I don't k...

The manual says that directive absolute is for variables, and directive org is for "a constant or a routine in ROM". I don't see a way to point a procedure to RAM. Is there an easy way to put a small amount of code (specifically ISRs) in RAM to reduce wait states?

That seems pretty straightforward. Instead of the Microchip C (for example),

bumf = VirtToPhys(&U1RXREG)

if I read that correctly, you simply use

bumf = U1RXREG & 0x1FFFFFFF

Am I missing anything?

It's almost a year later. I take it we're not going to see anything in support of this?

I'm not sure what you're trying to do, but you may want to consider setting up a DMA channel to do the SPI transfers independently of the CPU. AFAIK, there's no library support for this. You have to do it the hard way.

This isn't clear. Does 'volatile' exist in MP, or is this a request?

I've run in to this before, and used a dummy assignment to keep the optimizer from eliminating the variable, but that takes up precious cycles in an interrupt routine.

Especially since we were promised a PIC32 update the minute the PIC32MZ hardware became available, which was earlier this year...

Fast graphics is fine and good, but embedded applications often hinge on peripherals. How do you do ethernet or wifi or how many uarts does this thing have? USB modes? Bluetooth? We're not talking about the important details.

Filip, This is sort of wandering off topic, but with all of this code written for XP, and Microsoft pulling the plug on XP, maybe this is a good time for mE to get serious about making Linux versions of everything. Right now, I'm migrating everything to Linux, and the only reason I'm keeping my XP b...

Sometimes I wish that there was an easy switch to defeat the optimizer for testing purposes. When you have one of these mysteries, that would be an easy thing to try, and you could confirm where to start looking.

I'll second this. There are some applications where sending SMS is too much fooling around (and may wear out the SIM card), and DTMF is a more suitable solution. The GSM modules generally have DTMF generating AT commands, but the PIC needs to be able to decode it from the audio. Sometimes this may b...

What some people do is provide a ZIP instead of a MPKG. As far as the listing is concerned, I'd rather have just plain text that can easily be copied and pasted. PDF is only worthwhile when you have pictures or when formatting is critical. IMO, the best thing to do is: 1) Create the mpkg 2) Place th...
