Forum Post: MSP430F5418A MCLK vs. VCORE problems, Flash corruption etc.
Using the MSP430F5418A microcontroller, we intend to run with an MCLK frequency of 16MHz eventually. FIrst we start at a lower frequency. We are shifting the VCORE voltage setting to 1.8V in one swell...

I think there must be a drv.c/.h set-up issue for the F28027F and the HVMTR KIT, and possibly the DRV8301 EVM which effected Manu36. Manu, did you ever get the LAUNCHXL-F28027F and BOOSTXL-DRV8301 to...

considering the SpeedEst and dyno don't quite agree, and you stall (estimator may be losing sync) I'd guess the Ls value took a guess on is not correct.Try lowering this to say 40uH (lower Ls is always...

This is not a code testing center.You should know whether your code is correct and does what you want - or not. Did you ever run it? If so, you know the answer.If you code is not correct, and you can't...

Depending on the conversion time, switching between an A4->A0 sequence and a single A12 conversion may take more time than sampling through the superfluous channels in a single sequence.However,...

After switching on, the reference takes some time to settle. As long as it is still below your input voltage, you will always get 0x3FF. You call wait(1), but depending on implementation of this...

It's possible that you stressed the port pins beyond limits. To protect the port pins against negative or overvoltage, they have clamp diodes connected to VCC and GND. However, if you stress them too...

On non-A devices, maximum speed was 18MHz, so you have been closer to the max speed.It is possible that your crystal has hiccups on ESD event, causing short CPU cycles. On A version, you have more...

Break your project down into smaller steps. First, make the SPI work. Test it with the EEprom (it is the easier part). Check whether read and write work as intended. Then access the accelerometer...
