XMC LED Current Control Explorer - Example A3

HUMAN EYE

COMPARATOR REFERENCE

OUTPUT STAGE

VDC IN

How to program the microcontroller:
1. Build project in DAVE
2. Pack together the .hex and .elf files into a .zip
(usually found in the Debug folder)
3. Click on the microcontroller symbol
4. Click on the "MCU-code" details
5. Select "Upload"
6. Select the .zip file created earlier
7. Click "Upload"
8. Click "OK"

This example demonstrates modulated peak-current control on one LED channel,
based on the DAVE project "LED_CCEXP_A3_ACMP_BCCU_CCU4".

The following code lines have been changed to speed up initialization, simplify
potentiometer behavior, and show internal signals:
(line 62) #define OFFTIME (0xB)
(line 63) #define WALKTIME (0x0)
(line 89) .fclk_ps = 0x60,
(line 255) XMC_GPIO_SetMode(P0_7, XMC_GPIO_MODE_OUTPUT_PUSH_PULL_ALT1);
(line 276) dimlevel = potresult;
