comment I2C communication between MPU6050 and MSP430FR2433
@CL. Yes, just found the GY-521 schematic :-) Anyway, the pulldown may be broken ;-) But I agree it's more likely that there's a connection issue.

Schematic? Are you sure that your MPU is powered correctly and pin AD0 is LOW?

comment Reading 32 ADC channels
@Rokta 18Mbit/s is indeed quite fast for an SPI. But we need about 10 MB/s here ;-) And a DMA transfer may need more than 7 clock cycles - didn't check the datasheet (but I doubt it's specified at all)

comment Different led voltages for different colors
@MatthewHill If you want a voltage dependent LED color, then how about searching for "voltage dependent LED color"? Google gives me this as first result: edn.com/design/power-management/4329054/… It's an MCU based solution using an ADC input and three PWM outputs, which gives you maximum flexibility. But I'm sure there are simple "hardware only" solutions, too.

comment Different led voltages for different colors
I do in electronics for about 15 years now (Ok, it's mainly SW development, but anyway!), and I don't understand what you actually want...? What are your requirements, if "household ones" are "no good"? An LED itself will not "be different colours at different voltages". An LED of a specific color needs a specific forward voltage for a specific current.

comment Number of bits relation to data UART
Of course, if you write that 30 bytes to your transmit buffer, it will transmit that 30 bytes - assumed you have set "8 bit datalength". There are implementations that allow data lengths below 8 bit. In this case it would be up to you to split your values to not lose information. Writing a byte to the buffer, but having "6 bit" data length would just ignore the two remaining (usually upper) bits.

comment How does an ultrasonic distance sensor work?
How about watching some tutorials? For instance howtomechatronics.com/tutorials/arduino/… > how does the Arduino / microcontroller convert this information into time? With the sensor from the example above: Using an edge sensitive timer: Start counting when the rising edge occurs and stop at falling edge. <br>

comment SAM Timer counter / atmel ASF
Apart from that your question isn't Electrical Engineering related: Where in your software do you tell the build tool that "TC2_Handler" shall be your ISR?
