Hello everyone, I'm trying to use the DMA to send a string out to my UART and unfortunately, while the example code that TI provides works, my code does not. #include #include #include "msp430x26x.h" #define BUFFER_SIZE 16 char uart_out[2*BUFFER_SIZE+1]; int main( void ) { int i; // Stop watchdog timer to prevent time out reset WDTCTL = WDTPW + WDTHOL

Does anyone know if it is possible to speed up startup of the MSP430F5438 chip by increasing the processor speed to 16 mHz in the Lowinit function? I am stopping the watchdog timer there but don't know if it is possible to speed up the processor. Also, is it possible to choose not to initialize the segments here and then later in my startup code, initialize all the variables that need initia...

Hejsan folks, I have crashed into situation where compiler produces code that in one instance works and in the other does not. The difference between the codes is a string inside a sprintf-command. This shows up elsewhere in function by that watchdog reset stops working/reboot sequence fails in illegal command.(!!!!) This difference between the codes is very trivial, should not affect the

Hello Group, I have a very weird problem. I am using an MSP430F5528 CPU, running the FLL at 8MHz (fixed, we don't change it). The system has a 3.0V LDO with 250mA current limitation. From time to time (4 to 12 times in 24 hours), the CPU will become stuck and only an external NMI will be able to reset the device. We have an external circuit that acts like a watchdog, if there is no edge c...

Hi, I need to measure the time between two external signals. These signals have big periods like 1 or 2 seconds. This way I'm trying to use the Timer B in Capture mode with counting of its overflows.

Dear all, I have a problem to setup the MCLK and SMCLK with FLL+ for MSP430F413, would you give me a help? The following is the code that I used to test the MCLK/SMCLK setting. I just try to setup the clock and then output it to P1.5 and P1.1 to check the frequency. And actually, I need a ~2 MHz MCLK void main( void ) { WDTCTL = WDTPW + WDTHOLD; // stop watchdog timer SCFI0 |= FN_4

I'm working with msp430F2013 making a code, i'm using IAR Workbench to make and debug the code. Part of this code consist in a delayer implement, and i used watchdog to make this Basically i used the RTI to increment a variable and test this variable in main code, when the test is true things would be done. The problem: I monitored the debug step by step and monitored the value of the v...

Hello, On my MSP430F5438 I've installed a watchdog timer. For test purposes I let this WDT timeout after 8secs. When it restarts I check SYSRSTIV (special vector to detect RESET resources). The vector indicates that a WDT timeout was the source of reset(PUC). Then my program starts but gets immediately reset due to a security violation. The SYSRSTIV contains the 0x0A code which is a security vi...

I'm trying to generate a power-up clear (PUC) on my MSP430F149 from software, and to do so without setting the WDTIFG bit in IFG1. That last piece is important because I'd like use WDTIFG to distinguish between watchdog-generated and software-generated PUCs. I had hoped to accomplish this with an FCTLx security key violation, but I've found that this action always sets WDTIFG in addition t

I am new to msp430. I am wondering if we are in lpm3 mode and timer_a running, how much power consumption it will take for a typical msp430. The data sheets seem to say a typical of 1 ua in lpm3 mode including watchdog timer running, but does not seem to say if that figure will hold if timer_a is also running.

Hi everyone, I'm working on a sensor project which uses TelosB based on msp430f1611 running TinyOS . My program is reset some time after boot up. After the PUC reset, IFG1 is found with WDTIFG bit set, indicating the watchdog timer initiates the reset. This can happen under two cases: 1) Watch
