Hello Infineon community.

Im currently working on a project with a TUSB1046 instead of a PS8740.

Changing the device adress and some registers worked for me to get the I2C_Write function working.

I was trying to get a read function based on the write function to work but its not working sofar.

the Write function in "datamux_ctrl.c" uses "MUX_CTRL_TX_FIFO_WR_REG" to transfering the Register address and Data to the TUSB.

But when i try to read it stays empty, on the other hand, the "MUX_CTRL_RX_FIFO_RD_REG" gets flooded with 0xFF's.

Following the instructions for I2C in the TUSB1046 manual:

1. generate a start condition (S) with Device-slave address and a Zero-value "W/R" bit .
2. wait for ACK from TUSB.
3. write the sub-address i want to read from.
4. wait for ACK from TUSB.
5. terminate operation with a stop condition (P)
6. generate a start condition (S) with Device-slave address and a one-value "W/R" bit .
7. wait for ACK from TUSB.
8. one byte of data should now arrive at TX/RX register and the TUSB1046 should be waiting for an ACK or NACK.
9. Generate a NACK.
10. terminate operation with a stop condition (P)

The full code-snipped is in the attached text file.

Hi, All,

  as we known the FX2 and FX3 SDK contain Driver and C#/C++ lib for windows  platform.

  Does Cypress Driver support windows 11 ?

   Does Cypress provide C#/C++ lib for windows 11??

Hi, 

I am using the CYPD3120 in a custom USB-C receptacle to DP sink design (4x DP1.4 lanes). This board will have an external MCU onboard, and given we are not using a redriver or high speed switch (such as TUSB564) on the 4 data lanes, the MCU will need to know when the USB-C cable is flipped to also flip the lane polarity at the DP sink directly.

Is there an accessible interface on CYPD3120 that allows access to read/write registers from an external MCU? I see examples of I2C (pins 36, 37) connected to an external controller on the CYPD3125 application note, but I am not sure if something similar applies to CYPD3120. Where could I go to read more about how this interaction is done?

Thank you,

Brian

Hello,

I´m searchnig for solution how to convert MIPI C-PHY 1.0 camera signal (sony imx 586 trial lanes) to HDMI, have Infineon some solution like CYUSB3065 but with HDIM output ?  Or i must do it through some FPGA or ? 

Hello Support,

My customer want to use HX2LP.

Can you tell me the recommended pattern for HX2LP?

Best regards,

Koki
