Hello all, I have a quick question if you can help me please? I am working on MSP430F5529. When I set the P1.0 as output and PS1.0 as one to output the digital clock. When I look at this clock on Oscilloscope I see the signal swings from 0.90 to 2.6V rather than from Zero to 3.0 Volts. High Regards, John ------------------------------------

Glitches with ADC12 internal temperature sensor

Hi all, I'm trying out the internal temperature sensor on an MSP430F449 with the ADC12. Most of the samples I get are within a few counts of the median, but some, maybe less than 10%, are 15 counts off, usually low. The MSP430 is on an Olimex development board, which seems to have all the recommended power and reference capacitors. I suspect I'm doing something wrong in my code, so I'd ...

Hello! How are you all doing? Hope everything's fine. So, i'm trying to do the following: Timer ---triggers--> ADC --samples--> DMA --moves to memmory--> end Right now, i'm facing problems with the timmer and ADC interfacing. The way i want it to works is that the timmer (not using its interruption) = auto triggers adc samples. NOTE: I've already made timmer starts ADC sampling with

Hey, guys! Anyone knows if "block transfer" + "decrement source address" is a valid op= eration in DMA? I'm trying to send the int 0x1011 as a block, but 0x10 must be sent prior t= o 0x11. I thought maybe this would work fine, but up to now, nothing.... Any suggestions? DMA0CTL |=3D DMA0TSEL_0;=20 /* PASSO 2*/ //unsigned int endereco =3D 0x0000; DMA0CTL |=3D DMASRCINC...

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 am working with MSP430F1611.It will read a frequency input from another sensor from TI.I have made the full pcb packaging as compact as possible so that the power supply module and all other components fit into a 98*98*58mm IP65 compact enclosure. I have kept this product powered ON continously for nearly a month and observed that the frequecy count is getting reduced .IS this problem due...
