NCP1247USBPDGEVB: Fixed Frequency Current Mode PWM Controller Evaluation Board

Overview

The NCP1247USBPDGEVB evaluation board is a flyback-topology switched-mode power supply designed for USB PD (power delivery) applications. It works in input voltage range from 90 Vac to 265 Vac and provides the output voltages 5 V, 12 V and 20 V up to 3 A of output current. The regulation of switched-mode power supply is ensured by the NCP1247 – a new fixed frequency current mode PWM controller with HV startup. The output voltage value (5 V, 12 V or 20 V) is set by the MCU controller CYPD1132-16SXI.
The CCG1 Host Board from Cypress Semiconductor can be used for an easy demonstration how the power supply for USB PD application works. Communication between the NCP1247USBPDGEVB evaluation board and CCG1 Host Board is ensured by a USB Type-C cable (it uses the CC wire for communication and the VBUS wire for energy transmission).

I would like to ask how to use RIL to handle incoming calls. Is there any way to prevent the system from receiving RIL_NOTIFY_RING and RIL_NOTIFY_CALLERID, and then handle these messages myself?

First of all, I would like to thank eeworld and Mr. Zhang Jindong for organizing this event~ so that I can have such a beautiful development board~[/font][/color] [color=#000][font=宋体]I couldn't wait
The LCD screen scrolls!
In the previous article, I wrote about the display program of 1602 LCD. Now it is very simple to move the LCD display screen. Let’s try it! （This experiment has been tested on the development board of
