Software flow
The software contains a test function executed at the start and two run modes.
For live documentation of the RH850 actions connect your computer via the COM-Port to the
UART connector “CN4” of the board.
Note: Use a 1:1 RS232 computer cable and a baud-rate of 9600.
6.1 StartUp Test
Once started, the clock will be initialized and a start-up test is performed. During the test, the
LEDs of the Blue LED Circle will successively be turned on and then turned off in the same
pattern. Simultaneously the RGB LED will sweep through different colors and then turn off.
Afterwards the RGB LED will light up in white for 500ms, as well as the whole Blue LED Circle.
LED1 and LED2 will light during the whole test. The Serial Interfaces CAN, LIN and Ethernet (if
provided), the Display availability and the RGB LED PWM feedback signals are checked. The
result is printed out in the debugger and via UART. After this the SW continues with Mode 1.
6.2 Mode 1
LED1 and LED2 glow in different intensities depending on the potentiometer POT1 position. The
converted analogue value of POT1 is used to update the duty cycle of the PWM module which
drives these LEDs. The LEDs of the Blue LED Circle follow the Rotary Encoder ENC1. By
pressing the Rotary Encoder Pushbutton, the color of the RGB LED is changed.
The load current through each of the RGB LEDs is evaluated by converting feedback/sense
