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...


Watchdog timer issue

Hi, We're running a program in a while loop and we believe we disable the Watchdog correctly in the beginning. The program runs correctly and never resets the CPU (by never I mean for at least 24 hours). However, when we go into a specific state and execute a specific block of code afterwards we get interrupted but it seems that it's stuck in the main loop. We're using mspgcc and mspdebu...

I'm in the process of writing something about the MSP430 and spent a couple of hours today looking around at the different tools that are front and center (with or without code limits) when looking for a toolchain for the MSP430 and hobbyists (not considering professional work right now, though such details may be added.) Straight off, I admit I'm used to using IAR's toolchain when writin...

This question has probably been answered a thousand times but it's worthy of 1001. You see these wonderful names like TACCR0 and P1DIR or WDTPW or WDTCTL or WDTHOLD or BCSCTL1. I could go down through all the header files, find all the #define statements and try to sort them out using the often absent comment statements, but that doesn't make much sense. Obviously I missed something But I don't ...

Hi everyone, I'm working on a sensor project which uses TelosB based on CC2420 and MSP430F1611 running TinyOS . And I want to timestamp each incoming packet, whose reception time is indicated by the SFD pin rising of CC2420. The SFD pin of CC2420 is connected to P4.1/TB1 of MSP430F1611 as se

I have been trying to get evaluation kits on the Silabs Si4463 but they never seem to be available, although they are listed. Distributors also seem to have problems and I now wonder if it is wise to keep on with it as I may not get supplies. Can anyone recommend a chip solution for a 151MHz transceiver? I only need 100mW. I know there are modules out there but rather expensive. TIA ...

Hello! I'm working with msp430f2619. I'm using it to sample audio. Fs is equal to 20K Hz, working with 96K B sample. 1) When playing back my low-frequency sampled signal (from 20 to 200 Hz BW), the audio is crackling, full of clicks.... 2) When sampling my voice (just to check if wav algorithm is ok) i can hear the phrase i just recorded (it's not the best audio record in the world, b...


Power Loss while erasing flash memory on MSP430F5438

Good morning, We have a device that monitors supply voltage vcc using the built-in supply voltage monitor and causes an interrupt if the voltage falls. The ISR calls a function ShutdownSaveData that writes 10 parameters to flash memory and sets a flag indicating that the saved data is there. On powerup, I check for the flag and, if present, I read the saved parameters into ram. I then era...

Hello! Hope you guys can help me: I just get my fir filter working fine! I'm sampling sound with sample frequency of 10 KHz and using a 128 tap low pass fir filter ( pass from 0 to 500 Hz). The algorithm i'm using is this one: void filtering(void) { DAC12_0DAT =3D (signed int)out+ 2048; //1) previous result to output sample[0] =3D ADC12MEM0 - 2048; //2) stores sample ...
