# svd2cpp
|
||||
|
||||
Zero-cost abstraction register library generator.
|
||||
|
||||
## What is *svd2cpp*?
|
||||
*svd2cpp* is a generator that parses .svd files provided by ARM chip vendor.
|
||||
It generates header file that allows for reading and writing to microcontroller's registers with zero overhead.

*svd2cpp* is a generator that parses .svd files provided by ARM chip vendor. It generates header file that allows for reading and writing to microcontroller's registers with zero overhead.
|
||||
|
||||
### Benefits
|
||||
1. **Compile-time checking.** This is an aspect that is making this solution better than any other parser/pre-generated header.
|
||||
* You won't be able to write to wrong register.
|
||||
* You won't be able to write wrong value (i.e. 0b1011 to 3-bit field) to register.
|
||||
* You can't read from write-only or write to read-only register.
|
||||
Any attempt to do something wrong will succeed in error at **compile-time** - no more runtime debugging to find out misspelling errors!
|
||||
2. **Zero-cost abstraction.** Another strong aspect of headers generated by *svd2cpp* is that using it in code will result in zero overhead because all of the checking is done at compile-time.
|
||||
3. **Portability.** As long as manufacturer provides .svd files in CMSIS-SVD format (and most major manufacturers of Cortex-M based chips does), you can use it with this parser.

||||
## How to get *svd2cpp*?
|
||||
Download source code and compile it. Note that this repo uses submodules thus do not forget to `git submodule init` and `git submodule update` after cloning.
|
||||
|
||||
OR
|
||||
Clone the repository, get submodules, compile.
|
||||
|
||||
Download precompiled parser.
|
||||
```bash
|
||||
~$ git clone https://github.com/supleed2/svd2cpp.git
|
||||
~$ cd svd2cpp
|
||||
~/svd2cpp$ git submodule init && git submodule update
|
||||
~/svd2cpp$ mkdir build && cd build
|
||||
~/svd2cpp/build$ cmake ..
|
||||
~/svd2cpp/build$ make
|
||||
```
|
||||
|
||||
## How to use *svd2cpp*?
|
||||
That's super easy:
|
||||
```console
|
||||
|
||||
```bash
|
||||
./svd2cpp -i svdFile.svd -o generatedHeader.hpp
|
||||
```
|
||||
|
||||
## How to use generated header?
|
||||
|
||||
After including header in your code, you can use all features such as *set*, *reset*, *read*.
|
||||
|
||||
Syntax is quite simple and easy to use:
|
||||
|
||||
```cpp
|
||||
operation<PERIPHERAL::REGISTER::FIELD>();
|
||||
```
|
||||
### Examples:
|
||||
In peripheral USART1: Set bit UE(USART enable) in CR1(Control Register 1):
|
||||
|
||||
```cpp
|
||||
set<USART1::CR1::UE>();
|
||||
```
|
||||
|
||||
In peripheral USART1: Reset bit UE(USART enable) in CR1(Control Register 1):
|
||||
|
||||
```cpp
|
||||
reset<USART1::CR1::UE>();
|
||||
```
|
||||
|
||||
In peripheral DMA1: Read TCIF1(Channel 1 Transfer Complete flag) in ISR:
|
||||
|
||||
```cpp
|
||||
bool transferComplete = read<DMA1::ISR::TCIF1>();
|
||||
```
|
||||
|
||||
In peripheral DMA1: Set MA(Memory address) for CMAR2(DMA channel 2 memory address register):
|
||||
|
||||
```cpp
|
||||
set<DMA1::CMAR2::MA>(0xDEADBEEF);
|
||||
```
