使用什么微控制器/将 Arduino c++ 转换为 AtmelStudio c++

Question

我正在努力研究如何将在我的 ATMega2560 上运行的这个项目缩小到一个更小的独立芯片。这些是芯片的标准：

24 个具有高电平、低电平、输入和 input_pullup 模式的 GPIO 引脚
串行读取兼容性
在内部振荡器上运行
在 JLCPCB 零件库中并且有现货 https://jlcpcb.com/parts
希望成本低

我认为 ATMEGA328PB-AU 是一个有效的选择，但我仍然不确定。

我已经知道如何将 Atmel Studio 7 代码上传到任何 avr 芯片，我只是不知道如何将我拥有的 arduino 代码转换为 Atmel Studio 7 代码。

注意：通过转换代码，我的意思是像更改 digitalWrite 和 pinMode 函数以直接使用 GPIO B、C、D 和 E 寄存器以获得更好的效率以及将 delayMicroseconds() 更改为_delay_ms

代码

typedef struct {
  unsigned int com : 4;
  unsigned int pin : 4;
} pair;

typedef struct {
  unsigned int A : 1;
  unsigned int B : 1;
  unsigned int C : 1;
  unsigned int D : 1;
  unsigned int E : 1;
  unsigned int F : 1;
  unsigned int G : 1;
} digit;

//hopefully these pins in the atmel studio 7 code will be defined by PB0, PB1, etc
//below the pin assignments are just random numbers
const byte comPins[8] = {1,2,3,4,5,6,7,8};
const byte regPins[16] = {9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24};

你试过用现在的Microchip Studio（原Atmel Studio）导入Arduino工程吗，这个版本能用吗？

根据Microchip的描述，应该可以用Microchip Studio导入Arduino工程：

Microchip Studio can also import your Arduino® sketches as C++ projects to provide you with a simple transition path from makerspace to marketplace.
