    Just saw this free book from Geoffrey Brown , a guy i have had some dialouge with, after i did the Versaloon port to the STM32-VL-Discovery board.
     
    Looks like he did a nice work here

    Bingo600 got a reaction from bluehash in lpc 812 Max - arm-gcc blinky   
    If anyone else got a 1$ LPC812 Max board.
    http://www.embeddedartists.com/products/lpcxpresso/lpc812_max.php
     
    And want to do a blinky with arm-gcc , i just completed one with help from the below repos.
    https://github.com/sebseb7/lpc8xx
     
    1: Get the base repos
    git clone https://github.com/sebseb7/lpc8xx
     
    2: Extract the attached sources into the newly cloned lpc8xx dir.
     
    3: make
     
    4: insert the lpc812 MAX Board into an USB slot on the pc (it'll open a new file-explorer window , like an usb-disk)
    , pull the blinky.bin onto the "disk"
     
    5: Press the Reset Key on the board , and your program is running.
     
    I use linux , and arm-gcc from here https://launchpad.net/gcc-arm-embedded

    I've been writing on this chip over on 43oh.com. The lpc1114 seems more like an msp430 chip than the cortex-m4 chips this site is focused on. Besides, I can never remember how to spell stellarisiti.com

    Bingo600 got a reaction from Jigar4Electronics in newbie question! how do I use UARTprintf with floats?   
    Did you remember to let str  point at a something valid ?
    Using just str would garble something ...... Whatever str i pointing at ...
     
     
     
    { char buffer[20] , *str; str = buffer; ftoa(g,str) } or - just plain { char buffer[20];  ftoa(g,buffer); }    
     
    Ohh btw ... I didn't really look at the ftoa() , but shouldn't that generated string be terminated with a '\0' before returning

    Bingo600 got a reaction from bluehash in CCS license expired... now what?   
    I'm using Code::Blocks IDE 12.xx on Linux Mint 14.1 Mate - (fast and native as in not java)
    To avoid all the "plugin" issues , i'm using makefiles ... And not "Clicky..Clicky".
    This gives me the advantage of being able to compile for any arm-gcc supported mcu  TI,NXP,ST,Atmel.
     
    So primarily i use CB for editor , and the debugger (uses arm-gdb)
     
    Ohh and i second , using the "launchpad" arm compiler.
     
    I previously used CodeSourcery lite , but after Mentor took over i have abandoned due to all the register stuff.
     
    And i have a feeling that , while ARM was backing up CodeSourcey ($$) before the Mentor takeover.
    ARM have moved their support to the "launchpad" arm-gcc , and therefore the launchpad gcc is the one with the most recent features.

    Edit: I use this repos/ppa  (the stock CB is too old) -

    Arm is moving CMSIS from http://onarm.com to http://arm.com/cmsis , including the CMSIS forum to http://forums.arm.com/
     
    There is a CMSIS v3.01 (CMSIS-SP-00300-r3p1-00rel0.zip) on arm.com.
