USB EZ-PD™ Type-C Forum Discussions

Hi,

请问下我在使用PSoC Creator4.4打开电脑文件路径“C:\Program Files (x86)\Cypress\EZ-PD CCGx Host SDK\CCGx\Firmware\projects\CYPD4226-40LQXI_notebook\CYPD4226-40LQXI_notebook.cywrk的这个工程文件的时候，刚开始我是可以打开看的，后面关闭后，再打开就打不开了，然后下面提示了如下的这些信息，请问这是怎么回事呢？我应该怎么解决？

Customer would like to develop a C to DP / DP to C "bidirectional" dongle using CYPD3120 

Can you please provide us the reference firmware and hardware?

Hello Community,

I'm able to configure 5A in SrcCaps only for Fixed Supply type PDOs,

If I want to configure 5A for APDO supplytype, I'm unable to configure.

This can be considered as continuation to the below thread:

https://community.infineon.com/t5/USB-EZ-PD-Type-C/Preparing-and-initiating-SrcCaps-packet-with-5A-capability/td-p/327705

Can somebody help me out here. @Pranava_YN  ?

Thanks in advance,

Pranay

Hi,

我在使用 1.3.7版本的EZ-PD configuration utility 的时候，生成的文件有三个，一个是.c后缀，一个是.cyacd后缀, 一个是.xml后缀的文件，然后我在看这个文档的时候“EZ-PD Configuration Utility User Manual.pdf”，下面截图这里所说的部分，我的理解是.c后缀和.cyacd后缀的两个配置文件分别对应的两种烧录方式是么？那么这两种烧录方式分别是怎么样的？有什么不同？以及什么时候应该用哪一种呢？希望能得到您的解答，非常感谢。

Best regards,

Jiong

Hello,

There are examples for each IC on CCGx SDK 3.0.2

I would like to ask if there is any guide or examples to use CYPD3120 in the upstream mode and CYPD3123 in the dual-role mode.

I have tried to use the CTD upstream project for CYPD3123 -> change device to CYPD3120 but I am facing unmatch problem between Bootloader and Bootloadable.

Thank you!

Hi,

in my application I need roughly constant power, about 8W. This means that the current changes significantly from 5v to 20v, at which the circuit operates. The current setting is constant for every voltage RDO based on the resistor divider. The problem is that, if I base the current setting on 5v, I would need more than 1A,  which at 20v might fail since most adapters are 20/25W. If I base the setting on 20v, the current would be insufficient for 5v. It would be barely enough at 9v.

Is there a way to change the current setting based on the current voltage? Are all PD supplies capable of at least 9v?

What happens if a PC, which is PD capable, only gives 5v, 1A?

Thanks

Since I am considering the Artwork design of PMG1-S3 (CYPM1311),

Please tell me the maximum allowable current value of 31pin VBUS-C of CYPM311.

- Example code: Any example code for CYPD3120 or CYPD3123

- PSoC version: 4.4 or 4.5

- PSoC IDE setting: 
+ If using default ARM toolchain: ARM GCC 5.4-2016-q2

-> Error: Build error:

Build error: passing argument 1 of 'memset' discards 'volatile' qualifier from pointer target type [-Werror=discarded-array-qualifiers]

+ If using MDK533

-> Error: 

cannot open source input file "stack_params.h": No such file or directory
  #include <stack_params.h>

 We got error messages even we use default GCC or MDK. Could you help to solve the problem?

Hi,

I have a CYPD3171 Sink-only application modeled after the Power Bank example, but without internal battery. So this is a sink-only application. The hardware connection is the same as the power bank where VBUS_IN_DISCHARGE on the TYPE_C connector side, and VBUS_C_MON_DISCHARGE is on the sink side of the consumer back-to-back FETs.

For the firmware, I modeled it like the power bank example (from the EVK), but I removed the source PDOs using EZ-PD Configuration Utility. When I plug my sink-only hardware to a power source, I can see a successful power contract negotiated using the PD Analyzer tool. However, the voltage monitored is at the TYPE_C connector. When I probe the voltage on the sink side of the consumer back-to-back FETs, I don't see the voltage.

Side note on additional changes: My sink PDO is a "battery PDO"-type. I defined "DISABLE_PDO_BATTERY 0" and "PDO_SNK_BATTERY_SUPP_DISABLE 0" in config.h according to instructions given by a moderator here.

Q1. Please let me know if I am missing something or need to modify additional code from the example to turn enable the consumer FETs so the power passes from the TYPE_C connector side to the other side of the consumer FETs.

Q2. My application is bus powered. There's no separate VDDD power. VDDD will be powered by the CYPD3171 internal regulator from VBUS. How do I make sure the internal regulator is enabled? In Configuration Utility, I enabled "VBUS powered" option under SKEDBE Configuration. Is that correct?

Thanks,
Jonathan
