MSP430f2274 Startup

If you are working with the IAR compiler, you want to define a function with the form

__intrinsic int __low_level_init(void)

and if you are working with Code Composer, the function form is

int _system_pre_init(void)

These functions are essentially called immediately after reset and before main.

See the documentation supplied with the compiler for additional details.

ih mr. Jim,

I'm a student and I have a problem with my MSP 430 RF2500SEH. The code examples that I have to measurement the temperature don't debbuging in IAR.

Probably they don't are the correct codes. Can you send me other code examples to measur the temperature?

Regards,

Saúl Costa

Hi Saul,

you can find a code example for temp measurement here http://focus.ti.com/lit/ml/slaa429/slaa429.pdf (click the link in the document to download the .zip-file with the sources). The example in question is msp430x21x2_adc10_temp.c.

Thank for your help,

but the code example in question is the acess point or the end device?

Do you know how can I calibrate the sensor of measurement?

There are a question like that in slau273c, but the answer is: " A temperature offset is stored in Flash, which is calibrated at production. If the offset is erased or is incorrect, it can be changed to an appropriate level fou your application"

Thanks for your help,

But I've an other problem: I use IAR compiler and I check the cheksum with the code application (SLAA221).

The IAR linker configuration is

I used the function:

crc16MakeBitwise2(CRC16_INIT_REM, CRC16_POLY, (uint8 *)0x8000,0xffdd-0x8000+1); /* poly = 0x8005, the code is in 0x8000 .. 0xFFDD, checksum in 0xffde .. 0xffdf.

I don't find the same CRC.

If you can help me.

Regards,

Ercik
