The TB6612 is a MOSFET based motor driver.
The functions are:
*void NU32_Initialize(void) - enables UART1 and UART4 at 115200 baud. UART4 starts with the interrupt at priority level 3, UART1 starts with no interrupt enabled
*void NU32_EnableUART1Interrupt(void) - enables the UART1 interrupt
*void NU32_WriteUART1(const char *) - call with the character array you wish to send, make the array with sprintf()
*void NU32_ReadUART1(char *, int) - call with the array you want to read into, and the maximum size of the array. The code will wait at this function and buffer all characters received until you send a '\r' or '\n' (by pressing [enter] on your keyboard)

Use the following table to determine the motor output:

To initialize the serial communication, call NU32_Initialize(), :

<pre>
NU32_Initialize();
</pre>

To write a string to the computer, use NU32_WriteUART1(charArray). The special characters '\r' and '\n' are carriage return and newline. Using them together puts the cursor on the next line.


<pre>
NU32_WriteUART1("\r\nHello World!\r\n");
</pre>


To write a string with the value of a variable in it, use sprintf(charArray,"%d") and NU32_WriteUART1(charArray).
