hello everyone,
i wrote a C programm to test the RAM (using IAR workbench). everything is fine.
now i want to use the output file (from the linker or so) to interface with the MSP430 via LabView (using the Flash Emulation Tool) and perform the test.
can someone give me a hint how to begin, or where to find some info about it. ?
thank you for any help.
Arthur said:i want to do something like this but using labview.
It is completely possible to do this with labview spending some time:) (I've made a reduced version of this programmer for including it in my labview production tools).
In the newest version of the FlashPro software, a labview library was created by Elprotronic for interfacing with her Programmer, juste select le LLB, this will list the command available, select which one you want and put on you vi.
It is possible to use the dll from the lite version but you have to build your own block to interface with the DLL and handle all the functionnality (what was made before elprotronic programm it's own library)
Here is an example of a VI to programm the msp430 (yet the autoprogram block is available directly from the LLB).
Before calling this VI, it is necessary to call the "read code file block" to put the code file in the fet memory. Using this fonctionnality requires to compile your file in .txt, the debug file is not compatible, and actually not used for this fonctonnality.
Begin with doing a really simple application, read code file from a path an put in on the MSP.
But yes, you will always need an IDE to code and compile your program, but it is not necessary for programming the MSP. You only have to send the compiled files to your customer.
I never used the Fet firware update function, as the update are really rare.
But if you interface the dll with the "call library function node" you have to manually set the parameters, then corresponding connectors will be displayed on the block.
For example:
Dll connection
Parameters configuration
And the use onf the call dll:
NOTE: this is the library made by Elprotronic
For connecting the programmer you have to call:
F_OpenInstancesAndFPAs but all is nice described in the elprotronic documentation.
Hi Arthur
You can use the "programming>numeric>numeric constant" and then change the parameter to display in hex format, but this is only useable with constant, but this could be use to know if all is ok.
What I usually do with "variable" is to define a global variable where I write and read the parameters. In this variable there is a list of numeric (single variable) and 1D array (more than one). The format has only matter for displaying information, you could use decimal or hex for programming, of course the value set should be the right one, but you will write the data in bytes in little endian, so if you use a 32 bits single parameter you have to transform it in 4 byte with the correct implementation, the follow image will present how I write a 32bits value on msp430:
So my multiple variale "interface" is a 1D array of 8bit integer, and I arrange the date before setting them in the array, I only do this with 16 bits variable, which is funny to do.
I think the buffer is the internal buffer of the FET, you probably have a command to write to it, but if you only want to programm some bytes, I think you should rather use the F_Memory_Write_Data function.
With the Elprotronic DLL there is different function for writing/reading the Buffer, depending the memory destination (RAM or Flash) and 0x0202 is a RAM address, and I never use the buffer function so I can't tell if it is ok or not, I use F_Memory_write and F_ReadCodeFile for writing a compiled file.
Don't forget you can only clear bit when you write on Flash, so you have to erase the Flash before writing to have the right value in it.
One other thing, you have to configure your FET before using it, something like:
Open connection -> initialise -> config the microcontroller type -> config the interface (Jtag/BSL) -> and so on
Hope it's help
