Welcome in the fascinating world of PSoCs!
There are several methods for sending an 8-bit value to port-pins, although this is "PIC-thinking" and not "PSoC thinking".
In PSoC world you usually use a communication interface to talk to another device, as you can see the parallel interface disapeared from the PC-world for a couple of reasons.
Using a control register module that is connected to the pins gives you the best control and even is capable of DMA which would free the CPU.
Getting the ADC-value and setting the control-register is the easiest way.
In the "System Reference Guide" (Help -> System Reference) you can get informations on how to set a complete port.
Ah, and by the way: The PSoC4 has got an ARM m0, not m3.
And: using the function "Create workspace Bundle" you can attach a complete project here, so that we all can have a look at.
This ap note discusses GPIO, creating logical ports out of pins, and writing
Just as an aside you posted in PSOC 4 forum, but called out PSOC 5. If you
are intending to use PSOC 4 there is no DelSig in it, only a SAR. But you can
do the same with the SAR.
Lastly you can use DMA (with DMA wizard) to transfer this data in the background
w/o intervention. There are example projects in Craetor to do this.
Thanks Bob and Dana for getting back to me so quickly. I was aware of the fact I'm mixing PSOC4 and PSOC5 parts in my original post. This was just a quickly thrown together test since I'm just starting. Initially I started the project based on the PSOC5 and I'm now moving it to the PSOC4 since I just got a Pioneer board to play with.
Although most of the reference material you both mentioned only seems to talk about single pin I/O, the approach of using a register seems to work. Clearly though, I have a LOT to learn.
Thanks again for your help!!!
Eric, the ap note I posted specifically has logical port creation
of width you choose, and APIs / register declarations to write to it.
