Fix Audio Windows on MAC

  [GUIDE]  DSDT override  eGPU error 12 fix (Windows only)   here   ◄  Mac owners  please work through this thread to solve error 12 before doing a  DSDT override here   ◄  pre-compiled  DSDT overrides   - load or use as reference when making your own   Introduction   A Windows system's DSDT table root bridge definition (ACPI PNP0A08 or PNP0A03) is usually confined to a reserved 32-bit space (under 4GB) budgetted to be large enough to host the notebook's PCIe devices. A watermark TOLUD value is then set and locked in the system firmware. Windows OS honors the root bridge definition and will allocate PCIe devices within it. macOS ignores the root bridge constraints as too does Linux when booted with the 'pci=noCRS' parameter. Neither of those OS require a  DSDT override  and can allocate freely in the huge 64-bit PCIe address space.   When retrofitting a eGPU, an   error 12 (This device cannot find ...

PIC18F4550 RB0 Interrupt

Interrupts! You use them to detect the change in pin status, timers, communication and so on. I’m sure if you reached this post in need of using interrupts (or having trouble with interrupts), then I assume you know what interrupts are and what you are trying to use. With XC8, using interrupts is programmatically simple, since most of the code layout is given to you by <xc.h>. Now setting up interrupts is as simple as using the keyword “interrupt” before the function which should be called when an interrupt happens. I am not going to cover the difference between C18 and XC8 (XC8 makes your life a lot easier), but I’ll show you how to use interrupts in XC8. This post will have only the input from pin change. The timer interrupt will be covered later in the timer chapter. I encourage you to read the datasheet in order to understand much better about interrupt registers. Make sure the IO pin you are going to use for interrupt actually has interrupt feature. Because I have see...
