The GNU system was developed to be 100% free software, free in the sense GCC was originally written as the compiler for the GNU operating system. The GNU Compiler Collection includes front ends forДЄda, Go, and D, as well as libraries for these languages (libstdc++.). However, to make sense of all of these macros, you will need to consult (and read, and re-read, and re-re-read) the datasheet for your part.- GNU Project GCC, the GNU Compiler Collection It'll look like this: (OSCCAL & (1 << CLKPCE)) Д«y using these different bitwise operations with predefined macros, we can directly control and query the state of the hardware by using this static memory map. When querying, we want an expression that returns nonzero if the bit was set (1), and zero if the bit was cleared (0). It will look something like this: OSCCAL = (OSCCAL & ~(1 << CLKPCE))

Here, we want to make it a 0, without affecting the other bits. I'll leave it to you to review bit operators and see how this works. To do this, we use an OR mask, as follows: OSCCAL = (OSCCAL | (1 << CLKPCE)) To set the bit, we want to make it a 1, without affecting any of the other bits. In order to talk about the bit here, I can do several things. For instance, bit 7 in OSCCAL is named CLKPCE (again, from the datasheet).Д¬LKPCE is most likely defined (at least in AVR libc - the standards vary) by: #define CLKPCE 7Д«ecause it defines the bit shift needed to get to the desired bit inside OSCCAL. Many bit positions are also given by macros as well. This offers the simultaneous advantage of allowing us to only read the value from the bit of interest, while not inadvertently changing any bits that we do not mean to toggle. As a result, we use bitwise operators (such as &, |, ~, >) to 'mask' off bits that we are interested in manipulating. Now, by writing OSCCAL = 0b10000000 (or whatever else I want to write that is allowable by the specifications in the datasheet) I can directly access and change the clock prescalar module for this part.Д«ut, often we are interested in the value of a single bit, not the entire byte. In a header file associated with the part (such as AVR libc).

For example, you could find // Clock Prescalar Register for ATMega328p To make this interface easier for programmers, people (the manufacturer or the community) will often create macros to these memory locations. Once again, these names are manufacturer and part specific. As a result, the datasheet will also (almost) always give a name to that particular location in memory that describes its functionality. The datasheet for the part will tell you the exact memory location to control different functionality. These are specific to the manufacturer, the part, and sometimes even how the part is configured. Microprocessors use a memory map to interface their hardware functionality with the software.Д«asically, there are static addresses in memory that the hardware will use to determine its functionality.
