I am bringing up a new board with an F28335 with a 30MHz crystal. The crystal is producing a 30MHz signal. I have not been able to connect to it with CCS (I will make a separate post on that) and...

I forgot to post my solution for why, in my case, the FlashPro430 JTAG was not working with IAR:My MSP430F2274 Spy-Bi-Wire setup included a custom programming board which included a 330ohm resistor...

By default the pins are general purpose inputs. No configuration is needed for inputs, you can just read the appropriate GPxDAT register bit. To change the pin to a general purpose output all you have...

Paul,120 kHz is unnecessary for InstaSPIN-FOC. Even with nearly 0 inductance motors we get excellent performance with 60 kHz maximum, and 45 KHz usually does nearly as well. The teeeeny tiny little...

The MSP does not have any OS that handles output or input. You'll have to write this code on your own (or link a library into your project that offers this).However, CCS offers a way to intercept the...

Ah, now I jus tnoticed something:you have mixed-up UCB0 and UCB1. Check your register writes, you're reading the wrong registers sometimes.To which physical pins did you connect the slave?

You should not use arithmetic addition operator (+) for combining bits. The compiler won't complain as it treats both as numbers, but depending on the operands, '+' and '|' (the binary OR operator)...

You aren't writing an initial state to P1OUT so the state of P1OUT will be the same as when you powered down the board. In the user's guide (http://www.ti.com/lit/ug/slau144j/slau144j.pdf pg.333)...
