i have MSP430 launchpad for that i downloaded iar
when i connect launchpad with pc using usb cable geting error that "usb device not recognized" and also there is no thing "MSP430 Application UART" in com port device manager
i am running this in xp-sp3.
so please tell me how to solve this problem?
See jumper configuration given in Manual came along with board. Also check drivers are connected properly or not.
Install iar before connecting launchpad.
Or it will show error. If installed than it must have no error
now I'm using MSP430g2553 with Launch Pad.
And now I have question about RAM and Flash Read Speed.
Usually when I compile program, it will run in the flash section. But my manager recommned if I wanna run faster,
I should run as RAM Function. ( But I didn't understand why )
So, is there any source or comments about RAM Read Speed and Flash Memory Read Speed?
I solved the recognition problem by disabling and reenabling the com port. And if I remember correctly I changed the com port to number 3.
Hello, I am having some big issues with a system using an MSP430. First, I am using some normally-open push buttons, where the GPIO port is configured as pull-up input. Usually it works okay, but sometimes after power-up the buttons do not work. It is odd because the rest of the code seems to execute okay. I have some led's on a front panel that are driven by and I2C to GPIO chip, and they are working so that tells me that much of my code is running. I am also toggling some pins in a timer ISR and I can see them toggling on an oscope.
The second problem may or may not be related to the first. When I have the problem described above, a hardware reset (to the Reset pin on MSP) will often clear the problem and the system works okay again. But I have several boards where the hardware reset does not work at all any more, ever, even when I don't have the non-responsive push-button problem. At one time the hardware resets on these boards worked but now they don't.
Another interesting fact is that the system has an event that will trigger all init() functions to be called. After this event occurs, the push-buttons are responsive again. This is without any hardware or software reset.
I'm at a loss for what to do. I am sequentially trying different things to isolate the problem. This is the first project where I have tried using the MSP430Ware Driver Library. There have been quite a few times when I have been debugging a program with the FET and Code Composer, where the program seemed to hang. I would hit the pause button and it was often stuck in a MSP430Ware driver. So, from those observations, my first attempt will be to remove the MSP430Ware for the push buttons. I really doubt this is the issue.
All the buttons are on the same port P2 and I am initializing them all in one operation. I was also thinking that maybe their could be a problem with setting all the pins to pull up at the same time. But the datasheet indicates something like 30kOhm (don't remember exactly) and the buttons are normally closed. So I doubt this would be causing an issue too.
Hopefully someone has had similar or experience or can give me suggestions. I will post progress as I make it.
We're developing underwater sensors, We using a Stellaris Cortex M4, but we need to get to lower levels of power consumption, we already have the most of development done, and we need to stick to all the resources that a M4 gives so moving completely to MSP430 is not an option. But we're exploring the option of using a MSP430 as a slave to turn off, the Stellaris and still be able to get a timer and a interrupt driven RS232 for polling
Does someone has done this before, or someone may have some suggestions on which MSP430 part to use, any feedback will be appreciated.
We have acquired an MSP-FET430U64 - USB PROGRAMMER and we have trouble geting the MSP430 Flash Gang Programer software to work with the FET430UIF device. We have tried difrent OS Windows platforms (XP X86, W7 X86, X64) using drivers and software provided with the instalation CD and also latest drivers and software prowided by www.ti.com. The flash programer status says : "ERROR:Sincronization failed. Programmer connected?" Also the COM port no. and baud rate are set correctly.
i am working on IAR embedded workbench6.4 software. in this i am not finding the COM ports in FETDEBUGGER menu which in OPTIONS menu ( i am using windows8 pro). please give the solution?
how to write the code to select 32,768 HZ in MSP430F1232?
I have just read that mspgcc has so fare stopped developmen due to TI and Red-hat have started development on a new back-end to the gcc. What are the status on this project? and when can we expect a first preview of the work.
@vimal sutariya I had the same problem. I'm not an IAR user, i'm using CCS normally and i realised that uart virtual device driver comes up with CCS aswell. Maybe it was implemented in IAR files aswell. Try going device manager, find your unrecognized device, click install driver and choose IAR folder. If you are a windows user OS would probably check out entire folder for the driver setup and eventually find it.
