USB EZ-PD™ Type-C Forum Discussions
Hi,
I have a CY4531 CCG3 Daughter Card which I am using standalone, without the CCG EVK Base Board.
To develop the software I use PSoC Creator 4.0 update 1. For I2C,SPI and UART I used the component catalog to add these components to the TopDesign.cysch. These components work fine I am able to control UART,I2C and SPI.
But now I am moving on to USB for this I have removed R48 and R49 from the CY4531 CCG3 Daughter Card and added 0E resistors on R51 and R52 and connected the USB Mini B (j7) to my PC.
In the component catalog there are only USB components which are incompatible (USBFS,USBMIDI,USBUART)
so these I cannot use. What I do now in my own main is control the functions in usb.c from the SDK directly.
- call usb_init() with my own usb_config_t structure
- call usb_enable()
- call usb_task from the mainloop.
When the program starts my pc detects a new device, so I see that the CY4531 USB block is started, but the enumeration fails.
Somehow the functions registered through usb_init's usb_config_t structure are never called
Is there something else that must be done to usb the USB block?
Regards
Marcel
Show LessHi,
I am evaluating the USB Power delivery protocol using the CCG3 EVK. I have the following questions regarding the power delivery profiles.
1. What is the default power delivery profile is selected during the power negotiation process?
2. When the Source/Sink switch from one power delivery profile to another?
Thanks in advance.

Hello,
I am utilizing the information provided by Cypress in an effort to implement a modified Dock/Monitor application described in the CCG2 USB Type-C Dock Revstar A reference design. I am using the USB-Billboard CY7C65210-24QFN to handle the high speed applications. However, I combined it with the reference design from the 60W Car Charger, which uses the CYPD2134-24QFN and the NCP81239 Buck/Boost controller to handle the power source application.
I have been referred to the EZ-PD Configuration Utility to implement the application, but implementing the CY7C65210 and the NCP81239 do not appear to be part of that Utility, unless I'm missing some information. Is there a reference source code for either reference design that I can use to start my own project in the PSoC Creator, thereby combining the two reference designs?
Thank you!
Show LessWe are looking to utilize USB-C power delivery via a mobile phone, in order to power our hardware.
From our experience, not all type C enabled mobile phones, support power delivery by default. We made a custom cable with the new termination (I.e. 56KOhm pull-down from CC to GND), so our device will automatically be detected as a DFP (or device), and the phone as a UFP (or master) for delivering power. Using this method, we only used the power lines as part of the cable assembly (data signals are left floating).
Do we need an "active" cable for negotiating such power drawing via the USB-C?

Show LessHi I have a project on hand to use CCG3 and NCP81239 as USB Type-C PD3.0 charging station. Can I use CCG2 60W Car Charger Reference Design as a design reference guide. My charging vault charge 10 HP USB C NB power bank or HP Notebook power bank, charge time for HP notebook power bank is less than 4hr, for HP USB-C NB power bank is less than 1 hr. Both of them are 6 cell 19200mAH. 6 set of voltage 5V, 9V, 10V, 12V, 15V, 20V all with output current of up to 3A.
Show LessHi,
I am not sure whether this is the right place to ask this question.
I am new to CCGx and billboard device. I received a request from customer which asks me to build something with a single billboard device connects to two CCG2 devices. I know billboard is used to negotiate with host about what alternate mode the container device supports. But the specification doesn't disclose more detail about it. So I have some questions, hope someone can help to answer it.
1. Does billboard detect the alternate modes or the modes are pre-defined in its firmware?
2. Can single Billboard serve multiple CCG2 ?
3. Will CCG2 write back some data to Billboard?
Thanks a lot.
Show LessDear Cy tech team,
Could you please explain me the role of CCG1 in this design? I think Type C to Legacy USB can be achieved with a single resistor. Please correct me if I'm wrong.
Tnx
Show LessHello,
For one of the application we are planning to use CCG1 as a Power delivery. My question is does the functionality of switching (Vsel1 and Vsel2) between the voltages inbuilt to the controller or do we have to switch some internal mux or control the Vsel1 and Vsel2.
BR,
Sreekanth
