STUSB4500的I2C地址映射？

你好，
 
STUSB4500完整寄存器映射即将在st.com的产品网页上提供。
在此期间，您可以通过联系技术支持中心获取更多信息：
https://www.st.com/content/st_com/en/support/support-home.htmlhttps://my.st.com/ols
 
上电时，设备使用存储在NVM内存中的配置。
您可以使用STSW-STUSB002工具生成的二进制文件，通过I2C接口写入NVM来更改默认NVM配置。
 
然后，在加载NVM之后，您还可以通过写入I2C寄存器来即时更改其配置。例如，您可以根据附加的电源功能将PDO更改为请求。
 
 
默认的STUSB4500 I2C从设备地址是：
- 二进制：0b01010000
- 十六进制8位：
读取为0x50
0x51表示写入
- 十六进制7位（无R / W位）：
0×28
 
 
要访问的R / W寄存器示例：
 
 
问候。

Hello,

The STUSB4500 full register map will be available soon on the product web-page at st.com.
On the meantime, you can get more information by contacting the technical support center:

• https://www.st.com/content/st_com/en/support/support-home.html
  
• https://my.st.com/ols
  

At power up, the device uses the configuration stored in the NVM memory.
You can change the default NVM config by writing the NVM with I2C interface, using the binary file generated by STSW-STUSB002 tool.

Then, after the NVM is loaded, you may also change its configuration on-the-fly by writing to the I2C registers. For instance you can change live the PDO to requests depending on the attached Power source capabilities.


The default STUSB4500 I2C slave address is :
- Binary: 0b01010000
- Hexadecimal 8bit:
0x50 for Read
0x51 for Write
- Hexadecimal 7bit (without R/W bit):
0x28


Example of R/W registers to access:

• Reg AddressRegister name
  
• 0x06BCD_TYPEC_REV_LOW
  
• 0x07BCD_TYPEC_REV_HIGH
  
• 0x08BCD_USBPD_REV_LOW
  
• 0x09BCD_USBPD_REV_HIGH
  
• 0x0ADEVICE_CAPAB_HIGH
  
• 0x0BALERT_STATUS_1
  
• 0x0CALERT_STATUS_1_MASK
  
• 0x0DPORT_STATUS_0
  
• 0x0EPORT_STATUS_1
  
• 0x0FTYPEC_MONITORING_STATUS_0
  
• 0x10TYPEC_MONITORING_STATUS_1
  
• 0x11CC_STATUS
  
• 0x70DPM_PDO_NUMB
  
• 0x85DPM_SNK_PDO1_0
  
• 0x86DPM_SNK_PDO1_1
  
• 0x87DPM_SNK_PDO1_2
  
• 0x88DPM_SNK_PDO1_3
  
• 0x89DPM_SNK_PDO2_0
  
• 0x8ADPM_SNK_PDO2_1
  
• 0x8BDPM_SNK_PDO2_2
  
• 0x8CDPM_SNK_PDO2_3
  

Regards.

谢谢，
这将暂时做到。

嗨，
 是否提供完整的STUSB4500寄存器文档？
我已向ST提交了技术请求，但我没有收到任何回复。



以下为原文

Hi,
Is the full STUSB4500 register documentation available yet?
I have submitted a technical request to ST but I haven't received any response.

嗨，
SW库可用于编程STUSB4500的NVM存储器。它包含解锁和访问NVM的算法。
在st.com上正式发布之前，在线支持团队应该能够提前提供给您



以下为原文

Hi,
A SW library is available to program the NVM memory of STUSB4500. It contains the algorithm to unlock and access the NVM.
The online support team should be able to provide it to you in advance, before the official publication on st.com

编程STUSB4500 NVM内存的一个更简单的替代方法是将STUSB4500 GUI与STM32 Nucleo板配合使用。
Nucleo板只需10美元。因此它是一种低成本的I2C编程工具，可以通过刷新正确的固件来使用。
https://www.st.com/en/evaluation-tools/nucleo-f072rb.html
 
您只需要将Nucleo板上的I2C引脚（SCL，SDA，GND）连接到位于STUSB4500的电路板的I2C引脚。
 
然后，您可以使用GUI配置设备。

以下为原文

A simpler alternative to program the STUSB4500 NVM memory is to use the STUSB4500 GUI with a STM32 Nucleo board.
The Nucleo board is only $10. So it is a low cost I2C programming tool, and ready to use by flashing the right firmware.
https://www.st.com/en/evaluation-tools/nucleo-f072rb.html

You just need to connect the I2C pins (SCL, SDA, GND) from the Nucleo board to the I2C pins of the board where is located STUSB4500.

Then you can use the GUI to configure the device.

嗨，
我仍然没有听到我的支持请求（案例ID 00065283）
 
我有可以和STSW-STUSB002一起使用的Nucleo板和STEVAL-ISC005V1板。
我一直试图通过监控板之间的IC2来对协议进行反向工程，但看起来它并不是一个简单的R / W寄存器协议。
 
如果协议被记录下来，当然会容易得多。
 
我想在目标板上使用micro来配置和监控STUSB4500在运行期间，以便我可以在测试时通过固件升级重新配置它。



以下为原文

Hi,
I have still heard back nothing from my support request (case Id 00065283)

I have the Nucleo board and the STEVAL-ISC005V1 board which I can use with STSW-STUSB002.
I have been attempting to reverse engineer the protocol by monitoring the IC2 between the boards but it appears it's not a simple R/W register protocol.

It would be much easier of course if the protocol was documented.

I would like to use the micro on my target board to configure and monitor the STUSB4500 during operation so that I can reconfigure it via firmware upgrades while I'm testing.

嗨，
如果您的应用中有微控制器，使用它通过I2C直接配置USB-PD控制器确实更方便。
 
有一个库可用于从微控制器配置STUSB4500。它将在ST审查过程完成时在线发布（这是任何出版物的必要过程）。
 
因此，目前在线支持服务是从ST获得帮助的合适场所。
但随着向新的在线支持工具的过渡，可能需要更长的时间才能级联到合适的支持团队。这可能就是您的机票尚未处理的原因。



以下为原文

Hi,
If you have a microcontroller in your application, indeed it is more convenient to use it to configure directly the USB-PD controller by I2C.

There is a library available to configure the STUSB4500 from a microcontroller. It will be published online when the ST reviewing process will complete (which is a required process for any publication).

So for now the online support service is the right place to go to get help from ST.
But with the transition to the new online support tool, it can take longer to cascade to the right support team. That may be why your ticket has not been processed yet.

嗨，
现在，我可以通过IIC寄存器动态调整PDO电压。（0x85~0x90）。
但我想知道如何通过MCU将NVM编程到STUSB4500？



以下为原文

Hi,
Now, I can ​dynamically adjust the PDOs voltage through the IIC register.(0x85~ 0x90).
but I want to know how to program NVM to STUSB4500 through MCU?

嗨，
有一个软件库可以通过MCU对STUSB45 NVM内存进行编程。
在公开发布之前，请联系在线支持以获取该软件。



以下为原文

Hi,
There is a software library to program the STUSB45 NVM memory with a MCU.
Please contact the online support to get the software before the public release.

大家好，
STEVAL-ISC005V1还有两个问题：
 
1个I2C上拉电阻各为2k2欧姆。当STEVAL-ISC005V1未上电时，它们正在杀死I2C通信。拆焊它们解决了这个问题。可能只需将SDA上拉电阻脱焊即可。
 
2文档中存在问题：UM2398（Rev01）第18页，图22：电阻（R82，R83）顺序与我所用电路板的顺序不匹配。



以下为原文

Hi All,
Two more issues with the STEVAL-ISC005V1:

1 I2C pullup resistors are 2k2 Ohm each. And they are killing I2C communication when the STEVAL-ISC005V1 is not powered. Unsoldering them fixed the problem. Possibly unsoldering SDA pullup resistor only could be enough.

2 There is a problem in the documentation: UM2398 (Rev01) page 18, Figure 22 : The resistors (R82, R83) order doesn't match the order in the board I have.
