Hi,
I have the CY4534 EZ-PD eval kit and using the EZ-PD BCR HPI Utility. Can you give a detailed description of the Registers? How many bits, etc.? The datasheet does not say how many bytes wide the registers are or how to crack them.
Thanks,

Hello,
After looking over all the documentation I could find (datasheet, source primer, etc.), I couldn’t easily find how I’m meant to connect IR LED (s) for Ir DA communication with an STM32WB55. The image I attached is a screenshot from the reference primer, which implies that there may be IrDA_OUT and, IN pins (I am interpreting this as being separate from the TX and RX pins). Am I supposed to add some intermediate IC for Ir DA, or can the STM32WB55 actually output signals for driving/ reading IR LEDs photodiodes?
I am aware of the actuality of the IR_OUT pins, but that’s its own separate thing. In the IR_OUT documentation, they use only timers (TIM16 & TIM17), not the US ART supplemental.
Thanks and Regards

Hello, IrDA has hardly been used for a long time, which is also marked in discontinued IrDA transceivers. However, since basically everything except the TIA and visual factors is included in the STM32 IrDA SIR ENDEC, it's possible to recreate IrDA with an IR LED plus driver transistor and an IR photRead more

RX and TX are switched to the IrDA function so that the LED driver and TIA can be connected directly.

Hi!
I’m applying the LED Control (LEDC) PWM to control the servo motor, it worked well.
And now I need to control further than 8, I’ve checked the ESP32 datasheet, and there have 16 channels can use 8 in High – speed mode, and 8 in Low – speed mode.
But the ledc library does not support low- speed mode right now, is there any way to use led pwn in low- speed mode?
Like, write the register directly?
thanks!

Not sure if the driver does not support all 16 channels. they may just not be supporting the low- speed option of the low- speed channels. But anyway, if you want to poke at the registers yourself, the LED PWM controller is documented in the TRM. Do not forget to actually turn the peripheral on, andRead more

The STLQ020PUR (flexible version) doesn't contain the discharge function. You can also find reference 2 in the data sheet, table 5, stating Rlow is( available)" on specific version only". In those specific versions( not released to the request yet) Rlow would be equivalent to the on- resistance of tRead more

In those specific versions( not released to the request yet) Rlow would be equivalent to the on- resistance of that switching FET marked with an asterisk visible infig. 2.

Hello, Sure, I can help with that.

Hello,
Sure, I can help with that. The CY4534 EZ-PD eval kit is based on the Cypress EZ-PD CCG3PA USB Type-C and Power Delivery controller, which has a set of registers that can be accessed and configured through the EZ-PD BCR HPI (Host Processor Interface) Utility.
The CCG3PA controller has a set of 256 registers, each of which is 16 bits wide. The registers are numbered from 0x0000 to 0x00FF in hexadecimal notation. The lower 8 bits of the register address determine which register is being accessed, and the upper 8 bits determine the type of access (read or write).
To access the registers using the EZ-PD BCR HPI Utility, you will need to connect the CY4534 eval kit to your PC and open the HPI Utility software. The software provides a graphical user interface that allows you to read from and write to the registers.
When you open the HPI Utility, you’ll need to connect to the CY4534 eval kit by selecting the appropriate serial port and baud rate. Once you’re connected, you can use the “Register Access” tab in the software to read from and write to the registers.
You can find more information about the CCG3PA controller and its registers in the datasheet provided by Cypress. The datasheet includes a register map and descriptions of each register’s function and configuration options.
Thank You
