How to use

Execute function corresponding to voltage:

• 5V: QC_GPIO_5V();
• 9V: QC_GPIO_9V();
• 12V: QC_GPIO_12V();
• 20V: QC_GPIO_20V();

For regulation (continuous) mode execute initialization and then set output voltage by using incrementation/decrementation functions (MAX 12V out):

• QC_GPIO_Reg();
• +0.2V: QC_GPIO_Inc();
• -0.2V: QC_GPIO_Dec();

Tested with different QC chargers (USB-A and USB-C)

For USB Type-C resistors 5.1k between CC1, CC2 and GND are neccessary
