Speed measurement - MSP430
Hi. I have an assignment at faculty to measure speed using incremental optical encoder (someone is using word rotary). Have anyone done the similar project maybe? I get 2 analog signals and I use DA converter at begging. I have several questions, for example do I have to deb-ounce the signals, or how to measure the frequency of signals (I can't use interrupts) Thanks in advance

MSP430 outputs high by default?
Sehe ich das richtig, dass im Gegensatz zum AVR das Ausgangsregister beim MSP430 nach Reset high ist und daher ein PxOUT = 0; notwendig ist, um sie beim Setzen des PxDIR Registers ausgeschaltet zu aktivieren?
Das dürftest du falsch sehen. Jedenfalls ist mir kein MSP bekannt bei dem das so wäre.

Turn off I2C on MSP430
Hello, i am developing a pcb for low power purposes and want to implement a i2c Bus for data transfer of several Ics. The µC is a CC430F5137 and is located on a diffrent pcb. My main goal is to reduce energyconsumption of the i2c-bus while not sending data. I just wondered if it is possible to just enable the internatl pull-up resistors of the µC to take the bus out of service to save energy. I found this comment in the Ti forum: "While this is obvious for normal I/O, this is important if you use the I2C controller where the output drives only to GND but not to VCC (open collector).

RF with MSP430 and CC1111 - Strange behaviour
Hey Folks, I wrote a MSP430 program that receives and transmits data in a fixed lenght format via RF. Everything there works fine: If I use one MSP to send data, another MSP, who is programmed to receive packets, receives them. Now I wanted to use a CC1111-Dongle to send packets and one MSP to receive them. But now the things start to become strange: I send exactly the same packets via RF, but the receiving MSP only receives the packets sent via the MSP and not the one from the CC1111
