求助，谁同时懂C#和C++，想把一段程序用C实现，有些细节...
本帖最后由 inkfish321 于 2013-9-7 16:07 编辑正在写一个BLE的上位机程序，但是NORDIC所给的例子只有C#,和DLL。提供C++的接口，但是没头文件。只有API的说明文档。
C#的部分代码如下：
using System;
using Nordicsemi;
namespace nRFUart
{
internal class PipeSetup
{
/* Public properties for accessing discovered pipe IDs */
public int UartRxPipe { get; private set; }
public int UartTxPipe { get; private set; }
MasterEmulator masterEmulator;
public PipeSetup(MasterEmulator master)
{
masterEmulator = master;
}
/// <summary>
/// Pipe setup is performed by sequentially adding services, characteristics and
/// descriptors. Pipes can be added to the characteristics and descriptors one wants
/// to have access to from the application during runtime. A pipe assignment must
/// be stated directly after the characteristic or descriptor it shall apply for.
/// The pipe type chosen will affect what operations can be performed on the pipe
/// at runtime. <see cref="Nordicsemi.PipeType"/>.
/// </summary>
///
public void PerformPipeSetup()
{
/* GAP service */
BtUuid uartOverBtleUuid = new BtUuid("6e400001b5a3f393e0a9e50e24dcca9e");
masterEmulator.SetupAddService(uartOverBtleUuid, PipeStore.Remote);
/* UART RX characteristic (RX from peripheral's viewpoint) */
BtUuid uartRxUuid = new BtUuid("6e400002b5a3f393e0a9e50e24dcca9e");
int uartRxMaxLength = 20;
byte[] uartRxData = null;
masterEmulator.SetupAddCharacteristicDefinition(uartRxUuid, uartRxMaxLength,
uartRxData);
/* Using pipe type Transmit to enable write operations */
UartRxPipe = masterEmulator.SetupAssignPipe(PipeType.Transmit);
/* UART TX characteristic (TX from peripheral's viewpoint) */
BtUuid UartTxUuid = new BtUuid("6e400003b5a3f393e0a9e50e24dcca9e");
int uartTxMaxLength = 20;
byte[] uartTxData = null;
masterEmulator.SetupAddCharacteristicDefinition(UartTxUuid, uartTxMaxLength,
uartTxData);
/* Using pipe type Receive to enable notify operations */
UartTxPipe = masterEmulator.SetupAssignPipe(PipeType.Receive);
}
}
}
我想用C来实现，这是我改的代码：
#define NRF_UART_RX_BUF_LENGTH 20
#define NRF_UART_TX_BUF_LENGTH 20
typedef struct _PedoNrfUartIo{
//public:
PedoIoTypeDef supper;
void (*StopScanning)(void *me);
//private:
uint8_t mPackHeadFlag1;
uint8_t mPackHeadFlag2;
uint32_t mReceiveCount;
uint32_t mSendCount;
uint32_t mBusy;
uint8_t mUartRxData;
uint8_t mUartTxData;
int32_t UartRxPipe;
int32_t UartTxPipe;
HINSTANCE hMasterEmulatorDll;
MasterEmulator *pMasterEmulator;
BtUuid *pUartOverBtleUuid;
BtUuid *pUartRxUuid;
BtUuid *pUartTxUuid;
}PedoNrfUartIoTypeDef;
PedoIoTypeDef* CreateNrfUartIo(void);
static void ClosePedoNrfUart(void *me)
{
PedoNrfUartIoTypeDef *this = (PedoNrfUartIoTypeDef *)me;
if(this == NULL)
return;
if(this->hMasterEmulatorDll != INVALID_HANDLE_VALUE)
{
AfxFreeLibrary(this->hMasterEmulatorDll);
}
if(this->pMasterEmulator != NULL)
{
delete(this->pMasterEmulator);
}
free(this);
}
PedoIoTypeDef* CreateNrfUartIo(void)
{
PedoNrfUartIoTypeDef *NrfUartIo = (PedoNrfUartIoTypeDef *)malloc(sizeof(PedoNrfUartIoTypeDef));
PedoIoTypeDef *supper = (PedoIoTypeDef *)NrfUartIo;
if(supper != NULL)
{
memset(NrfUartIo, 0, sizeof(PedoNrfUartIoTypeDef));
supper->GetIoType = &NrfUartGetIoType;
supper->GetPackHeadFlag = &NrfUartGetPackHeadFlag;
supper->UpdateIoState = &NrfUartUpdateIoState;
supper->CloseIo = &ClosePedoNrfUart;
supper->ReadPack = &NrfUartReadPack;
supper->SendPack = &NrfUartSendPack;
NrfUartIo->hMasterEmulatorDll = AfxLoadLibrary(_T("MasterEmulator.dll"));
//打开USB设备
}
else
{
return NULL;
}
if(this->hMasterEmulatorDll != INVALID_HANDLE_VALUE)
{
NrfUartIo->pMasterEmulator = new MasterEmulator();
NrfUartIo->pUartOverBtleUuid = new BtUuid("6e400001b5a3f393e0a9e50e24dcca9e");
NrfUartIo->pUartRxUuid = new BtUuid("6e400002b5a3f393e0a9e50e24dcca9e");
NrfUartIo->pUartTxUuid = new BtUuid("6e400003b5a3f393e0a9e50e24dcca9e");
}
else
{
supper->CloseIo();
return NULL;
}
if((NrfUartIo->pMasterEmulator != NULL) &&
(NrfUartIo->pUartOverBtleUuid != NULL)&&
(NrfUartIo->pUartRxUuid != NULL)&&
(NrfUartIo->pUartTxUuid != NULL))
{
MasterEmulator *pMasterEmulator = NrfUartIo->pMasterEmulator;
/* GAP service */
pMasterEmulator->SetupAddService(*NrfUartIo->pUartOverBtleUuid, PipeStore.Remote);
/* UART RX characteristic (RX from peripheral's viewpoint) */
pMasterEmulator->SetupAddCharacteristicDefinition(NrfUartIo->pUartRxUuid ,
NRF_UART_RX_BUF_LENGTH,
NrfUartIo->mUartRxData);
/* Using pipe type Transmit to enable write operations */
NrfUartIo->UartRxPipe = pMasterEmulator->SetupAssignPipe(PipeType.Transmit);
/* UART TX characteristic (TX from peripheral's viewpoint) */
pMasterEmulator->SetupAddCharacteristicDefinition(*NrfUartIo->pUartTxUuid,
NRF_UART_TX_BUF_LENGTH,
NrfUartIo->mUartTxData);
/* Using pipe type Receive to enable notify operations */
NrfUartIo->UartTxPipe = pMasterEmulator->SetupAssignPipe(PipeType.Receive);
}
else
{
supper->CloseIo();
return NULL;
}
return supper;
}
但是有很多问题不懂。例如用C++ NEW出来的类是不是该用类指针来代替。
另外看一下文档里提供的函数对照如下：
C#
public void SetupAddCharacteristicDefinition(
BtUuid characteristicUuid,
int maxDataLength,
byte[] data
)
Visual C++
public:
void SetupAddCharacteristicDefinition(
BtUuid^ characteristicUuid,
int maxDataLength,
array<unsigned char>^ data
)
C#
public void SetupAddService(
BtUuid serviceUuid,
PipeStore pipeStore
)
Visual C++
public:
void SetupAddService(
BtUuid^ serviceUuid,
PipeStore pipeStore
)
C#
public Collection<string> EnumerateUsb(
UsbDeviceType deviceType
)
Visual C++
public:
Collection<String^>^ EnumerateUsb(
UsbDeviceType deviceType
)
BtUuid^这个是什么意思？
Collection<String^>^这个又是什么意思？
还用C++ CLR编程？太费事了吧。除非它DLL是CLR的。
