When compiling binaries from source, what are the real-world differences between generating PIC objects or not? At what point down the road would someone say, "I should have generated/used PIC obje...
I have read about GCC's Options for Code Generation Conventions, but could not understand what "Generate position-independent code (PIC)" does. Please give an example to explain me what does it mean.
I'm currently developing an operating system that uses the limine bootloader and follows the limine boot protocol. However, I've encountered an issue: when I call init_PIC(), the CPU resets immedia...
I have a project that was built in MPLAB 8 using the Hi Tech C compiler. When I load it into MPLAB 8 to program a device I get a checksum (I use Unprotected checksum), then when I load it into MPLA...
My code builds fine in the MPLAB X IDE (v5.454), but for usability I want to use VS Code with the MPLAB extensions. My requirements include the use of the xc32 compiler v2.40. The example video doe...
PIC and PIE is the same concept. If this is correct, I would like to use PIC to stand for PIC/PIE. PIC seems to be an "Attribute" of binary code, which type of binary code can be executed regardless of which memory location it's loaded into. Is it correct? PIC/no-PIC have no strong relationship with statically/dynamically linked executable.
The test is on Ubuntu 12.04 64-bit. x86 architecture. I am confused about the concept Position Independent Executable (PIE) and Position Independent code (PIC), and I guess they are not orthogona...
For the PIC microcontroller's I prefer to work in assembly, however I am have issues setting it up. I installed MPLAB X IDE 6.15 and read that it doesn't come with any toolchains pre-installed and I am trying to figure out how to install the assembly toolchain. I downloaded a version of mpasm (from Microchip's website), however it doesn't work.
The issue stems from how the 8259A Programmable Interrupt Controller (PIC) processes commands. When you write 0x11 to the command register (port 0x20), you're actually initiating the PIC initialization sequence.
Enable interrupt There are several ways to disable an ISR on this PIC. Including: Use the DISI instruction, or clear the GIE bit, or alter interrupt priority levels. But I have chosen to clear the interrupt to enable bit of the specific interrupt bit in IECx. In this case, it is IEC1bits.U2TXIE because I am using UART2.
