TMS320F28075: Hi precision, low latency interrupt. Which interrupt to use.

Part Number: TMS320F28075
Other Parts Discussed in Thread: C2000WARE

Tool/software:

Hi Guys, I'm going to need some serious help on this one.

I've started a VGA project to generate 256 colors on a VGA monitor 640x480 resolution. So far all is working quite well but the picture is static and running in a thread.

I need my VGA assembly code display routine to be running in an interrupt so while the interrupt is displaying video data I can run other ASM routines like plotting pixels, drawing circles, etc.

I don't know much about interrupts so any help here would be VERY much appreciated.

C Code is ok but rather ASM code as I'm an assembly programmer and not a C programmer.

Thanks and hope to hear from you soon.

  • Hi Pete,

    Thanks for reaching out.

    You can know more about Interrupt controller by referring to Technical reference manual Chapter System Control and Interrupts section - 3.4 Peripheral Interrupts

    Then you can also look at the c2000ware examples but we don't have assembly code it will be either driverlib or bitfield programming.

    Thanks

  • Thank you Prarthan Bhatt. Looks like I have to do a LOT more reading. LOL.
