My project is to create synchronous rectifier for automotive alternator. I have already finished with the hardware (picture attached), now I need help with the software part. Basically it is three-phase bridge, created with low resistance MOSFET transistors, which need to be activated/deactivated at the precise time in order to turn input three-phase AC voltage into output one-phase DC voltage (12V). The hardware will be controlled with Texas Instruments F28069 controlSTICK microcontroller (this is a must), so I need somebody with experience in programming Texas Microcontrollers. For more details, please do not hesitate to contact me.

Display “Input joystick Y angle:” left aligned on the next line of the LCD and accept the angle input. Range -20° to +20° 4. Display “Input time in seconds:” left aligned on the next line of the LCD and accept the time input. Range 1 to 60 seconds 5. Display “Start?” left aligned on the next line and wait for a start input 6. The user has to move the joystick and match the input X and Y angle. If the user exactly matches the angle with in the input time, green LED of MK II board glows to show a win otherwise the red LED of the MK II board glows to show that the user has lost. When the user wins a beep tone is generated using the buzzer 7. The LCD should display a running elapsed time in seconds in the next available line 8. The LCD should also display the current X and Y angle of the joystick in the next available line 9. When the game is over, display “Start again?” left aligned in the next line and wait for the push button S1 (P1.1) input from the user to restart the game 10.
