No problem: just define a pin component(named "MyPort") with 8 pins. assign MyPort[7:0] to your required port.
Now a MyPort_Write(0b10101010) will write the pattern to the port.
Yeah, I did it the way you said. I created a port named HUB75 using Port 4 [7: 0]. I am writing 8-bit data to this port.
This is my code
These operations take 24us for 64Mhz cpu frequency. I can not increase the CPU frequency any more (for cy8c5868axi, max 68Mhz) Max data size 32. Can I use DMA to speed up this process?
Can you please post your complete project, so that we all can have a look at all of your settings. To do so, use
Creator->File->Create Workspace Bundle (minimal)
and attach the resulting file.
Furthermore: What are you exactly intending to perform? What kind of hardware is connected to that port?
