Other Parts Discussed in Thread: CCSTUDIO

Hello everyone.

I am  totaly new in ARM uControllers programing and in this forum as well. So I recently ordered Stelaris Launch Pad dev board with LM4F120H5QR. I can't find anything about this uC into the official Texas Instrument web site. May be I should search that chip with diferent name? Can you help me?

    Hi,

    The LM4F120 seris was rebranded - now it is labeled TM4C123xxx. It would be wise to be informed before buying. Your board can still be used as is, but you will have some difficulties when using the library. If possible, you may try to return it back and ask the new board TM4C123GXL.

    Petrei, thank You very much for your fast reply. I just noticed that the product I am receivng is not the obsolete one, but TM4C123GXL. May be they corrected my order automaticaly. Into the email I received from TI eStore I found this

    The reason I ordered this dev board is because it is recomended for beginners and the video tutorials I found in youtube. So, is the rebranded module compatible with the video tutorials I am starting with? I beleive this is the easiest way to get start. The compiler I am currently using is IAR embedded workbench. Is it good idea, or it is better to download CCStudio. I choosed IAR because it has SIZE LIMITED free version. Does the CCS have one? I apologize for my poor English and the multiple questions, but I have no one to introduce me into this matter.

    Hi,

    OK, you are on a good track. As for the toolchain, IAR is good without limits, if you can buy it. Otherwise, CCS does a good job and is unlimited and free to use with the purchased board. 

    Yes, start with tutorials, check out TI wiki about, should be there CCS to download and tutorials. Also, download the software package TivaWare, which is a peripheral driver library to be used with the micro.

    Good luck!

    Hey Radoslav (:

    may i toss Keil as an option into the pool? Keil MDK offers an automatic Pack Installer which lets you download the driver library and the CMSIS library to include them automatically..

    It freely supports projects with a code size up to 32KByte (Which you most likely will never top with your tutorials or any projects afterwards). For more, you'll need the licensed version.

    Also, be sure to download the TivaWare package as Petrei mentioned. It also includes Software Examples for specific boards, you'll find more on the webpage for your board.

    Sincerely,

    Thank you Petrei,

    Could you please guid me for, where to download the free CCStudio. I found this http://processors.wiki.ti.com/index.php/Download_CCS but I am not sure it is unlimited

    Because it is not unlimited.

    "After you have completed installation and run CCS for the first time it generate a free license that works with XDS100, development boards with onboard debug or for MSP430 users a 16KB code size limited license is generated"

    If you however feel more comfortable with an Eclipse-like Development Environment, CCS might be better for you. Yet like i said, Keil MDK is still a nice and viable option to try.

    Hello All,

    May I add OpenOCD which is free and unlimited and works well with GCC as well

    Regards
