I tried to read SoftwareVersion.BuildDate in Device Capabilities function provided MFDeploy Tool.
I searched assemblies, but I cannot figure out which one provide it.

How to read SoftwareVersion.BuildDate(in Device Capabilities) through code

ISR in interop
18 August 2014 - 10:54 PM
Hi, all.
I'm trying to put usart funcion in interop. I almost did it following the guide as below:
http://blogs.msdn.co...ework-v3-0.aspx
I implmented send function and data stream can be transfered in C# application through the class I made. But when I send packet through usart, the board just freeze when it get the stream. I want to figure out what is cause, so I debug through Keil project. But in that code, ISR part cannot be accessed with debugger (I cannot hit break point in that area)
I'm using USART2 in my board. Other functions look like this: Made from "generate stubs..." and tested it works in simple case. I thought ISR called when it get flag, so I just put native source in .cpp.
I wonder if I want to use ISR in interop, is there any special way of?

Porting usart for receiving data
12 August 2014 - 01:59 AM
Hi, all
I'm trying to solve stream-broken in usart through MF.
Through usart bus, 21760 bytes as speed of 250kbps should be transferred. When I tested with netduino based PK with large buffer(I modified RxQueue to receive all data), sometimes data is missing. Every time the index of missing is changing, so I think it is not related with logic in C# app.
Below is a part of netduino source related with USART.
void STM32_USART_Handle_RX_IRQ (int ComPortNum, USART_TypeDef* uart)
{
INTERRUPT_START;
char c = (char)(uart->DR); // read RX data
USART_AddCharToRxBuffer(ComPortNum, c);
Events_Set(SYSTEM_EVENT_FLAG_COM_IN);
INTERRUPT_END;
}
I thought it is related with AddCharToRxBuffer, so I used this test code in Keil with debugger.
(the length of data is fixed, so I used MAX_STRLEN for checking stream is finished)
?
void STM32_USART_Handle_RX_IRQ (int ComPortNum, USART_TypeDef* uart)
{
INTERRUPT_START;
if(cnt < MAX_STRLEN)
{
char c = (char)(uart->DR); // read RX data
received_string[cnt] = (char)(uart->DR);
cnt++;
}
else
{
for(int i = 0; i < MAX_STRLEN; i++)
{
USART_AddCharToRxBuffer(ComPortNum, received_string[i]);
Events_Set(SYSTEM_EVENT_FLAG_COM_IN);
}
cnt = 0;
}
INTERRUPT_END;
}
When I confirm the data in received_string array while PC is hang in else condition, the data is different with original one.
Now I am suppose it is timing issue.
- Usart Interrupt Clock or
- Thread/Timer issue related with other core function or
I'm not expert in native and embedded, so I'm checking every module one by one. I wonder which part can be related with this issue.
P.S. I tested also native example, and it works. So this is not hardware problem.
