Re: 160 byte framebuffer at 50 fps, internal RAM or external SRAM?

160bytes @ 50Hz is only 64kbits/s (average). Even SHIFTOUT should be able to handle that.
Running the SPI or MSSP module at a moderate 1Mbit/s will transfer those 160bytes in less than 2ms leaving...

Re: 160 byte framebuffer at 50 fps, internal RAM or external SRAM?

I think the bottleneck will be the serial interface speed (SPI) which is normally used in small OLEDs. I could not find this display WS0010B on searching for it. Unless the PIC supports a SPI DMA...

Re: 160 byte framebuffer at 50 fps, internal RAM or external SRAM?

Pretty much any external ram is going to be slower than internal storage.

Re: Command Line operation in a BATCH file

I'm now using MPASMWIN.EXE (even if the assembler's window says "MPASM v5.14") which solved the problem about the warnings.

Now, is there a way, like for Microcode Studio, to close this...

160 byte framebuffer at 50 fps, internal RAM or external SRAM?

Hello.
I'm doing a graphic project, where content of WS0010b OLED display will be updated really fast, 50fps at least.
The framebuffer size is 160 bytes. Will PBPs arraywrite/arrayread operations...

Re: 18F2580 with strange behaviour when using Hserin and RX interrupt

pll only works with primary clock sources , if you set the int-osc as primary clock then it works as expected

DEFINE OSC 32

OSCCON =% 01110000 '8MHz INTOSC
OSCTUNE=% 01000000 '

Re: Command Line operation ni a BATCH file

No, still not solved yet :frown:

When the batch file is launched with admin rights (I made a shortcut file to my batch to be able to launch it with admin rights), all HEX, ASM, etc files are not...

Re: Command Line operation ni a BATCH file

Problem solved: just needed to run the BATCH file with administrator's rights.
