Other Parts Discussed in Thread: MSP430F5529

Hi all,

After I compiled hello-world.c example file in ContikiOS and I got output in form of .txt file. Then I put it into MSPFlasher to executing code and the led blinks to RED in MSP430F5529 LaunchPad. Why does the led blink to red without printing " hello world" on the screen ?

Is your printer turned on? Is it connected to your system? Does it have paper?

Hi,

To understand how printf works on embedded systems, specifically MSP430 based, please read the following:

Hope this will help.

I don't really want to use CCS in my case because of spending too much time!

You will have same or similar issues with any microcontroller and any IDE.

Good luck.

MSPFlasher just puts the code into the flash of the target MSP. That's all. If the code wants to print something with printf, it has to be sent somewhere somehow. And someone must be ready to receive it.
MSPFlasher is just the postman that delivers a letter from the sender (compiler) to you (MSP). It doesn't care for its content nor whether you are able to read it at all or whether you might want to write an answer. It just cares for the post stamp (correct binary file format and checksum) and delivery into your mailbox (the MSP code flash memory). Everything else is outside its scope.
