DMA Channeling

[Brendan]

Furthering the power of Flowcode 7, itself supporting 32-bit micros with extended hardware features, I'd like to throw in DMA Channeling:

My rambling thoughts suggest a DMA component, enabling the user to individually nominate DMA channels afforded by the device for hardware-driven data piping direct to RAM, overcoming possible blocking processes, buffer limitations/overflows, etc..etc.. Incidentally, I recall that the PIC32MZ... can even generate an interrupt on user-defined data terminator strings - among other things, that might also feature in such a component.


Best regards,
Brendan

Hi Brendan,

From some of my past industrial projects DMA is a highly useful tool. However making a component that could work with many chips scares me a bit. I'll add it to the list as one to investigate as it would be very handy to have.

Thanks Ben... Scares me too, though just early food for thought for the more capable 32-bit PICs in particular.

We'll be running DMA for some of our projects, with C blocks managing available registers and memory space on these devices. Perhaps my rambling DMA ideas will shapen up once we've played a bit further.

All the best,

Brendan
