Hi,

Also I tried to find out library code between TUSB422 and MSP430G2553 communication through I2C but I didn't get any info.

So please provide library code between TUSB422 and MSP430G2553 if it is possible.

Hi Bhauthik,

The TUSB422 source code can be found on the product page (follow link below)

Could you clarify on what you mean by PD standard or non-standard? Would you like to identify devices that support PD communication or the PD version that is supported ?

Hello Malik,

Thanks for your response.

Actually I didn't found any code that you have already shared in previous loop.

Hi Bhautik,

Source needs to be requested, Please try the link below.

Proper connection should be determined via the CC1_State and CC2_State registers. USBC ports that support PD will respond to SOP messages with GoodCRC messages. You can program your micro to attempt PD message checking a pre-determined number of times and check TX_SOP_SUCCESS and TX_SOP_FAIL to see if the attached port support PD messaging.

Hello Malik,

USBC ports will respond to SOP messages with GoodCRC messages ===>> So respond will received automatically from controller side or required to read some I2C register?? If Is it possible to I2C register than when I can send read command for received SOP message?? and Is there any configuration before start the communication?? 

Also I tried to open link that you have shared with us but it's generated error message like below:

Regards,

Bhautik

Hi BHautik,

Please go to the TUSB422 product page and click the "Request software" link just above the Technical Documentation section of the page. TUSB422 code is best source to answer your questions. PD messages sent to TUSB422 need to be read from the RX buffer when interrupt is asserted in Alert register. I recommend going through section 7.3 Feature Description as it decries how to set TUSB422 to make a valid connection before PD messaging will start.  

Thanks Malik for your response.

I have understand the basic functionality at a high level through the shared code. Thank you for sharing it.

I have access the reference code and compile successfully in CCS without any issue. Also In that reference code found library folder like driverlib, hal, i2clib, PDlib and uartlib based on controller [MSP430FR5969].

I tried to find out library code based on MSP430FR2422 but didn't get it.

It will be great help if you can provide msp430fr2422 based library same as msp430fr5969.

Bhautik

Hi Bhautik, 

Unfortunately I only have MSP430FR5969 libraries to share for TUSB422 source code. 

Hello Malik,

I have got the driverlib for MSP430FR2422 [MSP420FR2xx_4xx] but did't get HAL and I2C library.

It will be great help if you can provide only HAL and I2C based library.

Is it possible to use any MSP430FR5xx_6xx series instead of MSP420FR2xx_4xx? If yes, so Is it working fine with HAL and I2C library without any issue? 

Thanks,

Bhautik
