    figuring things out - differences in 2452 and 2552?

    I only ever print out the first 20 pages of the datasheets, right before all the data and graphs start. And for the user guide, I only print modules that I am using....eventually you will have most of the modules printed as you learn each one. And I agree, I like having a datasheet printed, so I can make my notes.

    Porting problem (g2231 to g2452)

    Hmm, do you have another 2452 to test? or re-flash the default 1Mhz? I can test the code in a day, i have some un used g2452 lying around.

    USB dev (CCS code to GCC) issues

    success ... Rickta' s code works with the 5510.....lol I am so happy right now!!!

    USB dev (CCS code to GCC) issues

    I am having errors compiling some USB code on mspgcc, the code that I am having issues with is #ifdef __REGISTER_MODEL__ /* for IAR */ # if __REGISTER_MODEL__ == __REGISTER_MODEL_REG20__ # define __DMA_ACCESS_REG__ (void __data20 *) # else # define __DMA_ACCESS_REG__ (unsigned short) # endif #else /* for CCS */ # define __DMA_ACCESS_REG__ (__SFR_FARPTR)(unsigned long) #endif It affects how DMA0DA = __DMA_ACCESS_REG__ dest; //set destination for DMAx DMA0SA = __DMA_ACCESS_REG__ source; //set source for DMAx is there a suitable replacement for gcc that I can use? no amount of googling has helped. All I know is that SFR__FARPTR is a builtin but not sure what it does, or how it affects the code. If need be I can post the errors from compiling later today

    USB dev (CCS code to GCC) issues

    I just recieved Rickta's usb code he was working on and it works!!! Now to incorporate it into the newer usb dev api. full project to be posted after this weekend
  6. I think its a great tool to learn Arm and stellaris....Which opens the door to be able to create your own stellaris board for specific applications, or move on to bigger HW

    Porting problem (g2231 to g2452)

    use the crystal fault code to check your crystal. other wise your best bet is to connect it up to the debugger, then run it till you get the error and see where it is screwing up.... Sorry havent used NJs code yet

    MSP430 with USB support?

    can you post a link to your project, Right now I am working on porting over usb dev API to mspgcc (cdc, hid, msc) and I would like to see what you did

    USB dev (CCS code to GCC) issues

    Excellent! This will make things a bit easier. I will in the future work with the 20bit msp430s, but for now I will stick with the 5510 port of the code

    MSP430G2553 motor speed control with a potentiometer

    I would improve it by having the ADC just transfer the data to the variable automatically. so when the Timer ISR happens you can run your map function and change the pwm with out any real cpu usage outside of the isr. But otherwise I like your code, Simple and short and works

    one step closer...it now compiles but still won't enumerate on the host. i still have descriptors to edit and a bunch of debugging to do.

    Thanks pabigot for the info! is the f5510 a 20 bit msp? pabigot, is mspgcc-20120406, 20bit aware?

    USB dev (CCS code to GCC) issues

    From IRC -- Rickta __SFR_FARPTR is not jsut a function pointer. It' sprimary purpose is to represent a monolithic 20 bit value, as opposed to a long int value that is represented as 2*16 bit on assembly level. When stored to 'normal' memory, both are 4 byte size. But a normal long int will be put into 2*16 bit registers while an __SFR_FARPTR will be stored in a single register in a special 20 bit mode. Only this way, a 20 bit address can be properly

    @Iceman85 you should be safe from deletion, you have more then enough posts and are somewhat active.

    How would you use sensors to detect snow?

    not all traffic lights are the same. what about ones on poles, or hanging from cables strung across the road. The umbrella is an interesting idea, but what about wind? here in chicago, wind will blow and make snow stick to the side of the traffic lights.

    Different Duty Cycle Clocks

    yes you can get 6 outputs, you can use a software pwm, or use a shift register. but look on this forum for controlling multiple servos. i would.link to it but I'm on my phone.

    Help me pick linux flavor

    Ubuntu with gnome panel : large repository of software, ease of installation, it's my goto distro (at this time) what i dont like : unity.... openSuse : stable and well rounded. also no unity. debian : stable works on almost anything I have. lfs/blfs (linux from scratch) : challenging, custom, runs on anything, no unity. on the downside, one missed command and you bork your system and you have to start over. fyi this is not for every one but will give you major nerd cred.

    Help me pick linux flavor

    I like openSuse, or ubuntu with gnome panel, or debian. Right now on my main PC i run ubuntu 12.04 with gnome, on my dev PCs(3 others) I use BLFS with xfce4 .

    IR proximity detection

    I would go with the active ir one, also to increase distance you need more ir output ....lets make robots? had a big write up about that kind of setup....sorry on my phone other wise i would post a link

    microphone input

    I would not go any bigger than 220uF yes there is an equation to calculate it, but I forget at this time....wiki should have it on their filter page

    Mains Adapter & MSP430 32K Crystal problems.

    most power supplies are cheap.... even for name brand equipment, I found out the hard way when making an amplifier, 7 out of the 10 wall warts that I tried (from netgear, linksys, ericson, HP and some unknown brands from other equipment) had horrible noise on them...both switched and un-switched.....My thought is that most equipment builds in its filters for cheap power supplies.

    DigitalReadSerial.ino compilation error

    That looks like a regular Ubuntu GCC, not mspgcc you may have to download the mspgcc tools from ubuntu or use the script mentioned above

    Rectyfing and sensing small AC signal

    In theory you could just plug it in , but it might not turn out well ..... I used a full +-5v on the SDA16 on the F2013, it survived and still working I would try something like this, Signal------|(-------/\/\/\-----launchpad | with pull down or Signal-------|>|---------------launchpad led or diode capacitor is optional, but suggested for isolation and coupling

    Rectyfing and sensing small AC signal

    since you know what you are trying to read, I would try and just detect either the peaks and valleys. Just start the timer and start reading the time between the peaks or valleys. it should be pretty straight forward. LOL that sound card O-scope will definitely work when you don't have any other tools FYI I wouldn't worry about voltage, since it will frequency will give you better results, but the voltage increase is there it is just minimal from what I can tell.
