Dear Sir,

DPS368 as datasheet discription, it can detect the temperature, right? thanks.

The DPS368 is a miniaturized Digital
Barometric Air Pressure Sensor robust
against water, dust and humidity. It offers a
high accuracy and a low current
consumption, capable of measuring both
pressure and temperature. The pressure
sensor element is based on a capacitive
sensing principle which guarantees high
precision during temperature changes

How should I calculate the power consumption? Is there a spreadsheet that can be calculated?

The data sheet have IDDs. However, the number of descriptions is small and the conditions are quite limited.

Thanks,
Tetsuo

Can anyone please provide me with the BSDL file for the Cypress CPLD CY37512P208-83NI. I really need to JTAG program this part and have a STAPL file but need the BSDL.

Many thanks

What is the output impedance of CY27410?

In the "Test and Measurement Circuits" of the data sheet, the test environment is described as 50 ohms for single end and 100 Ω for differential. Is it this value?

Thanks,
Tetsuo

Hi Infineon,

I am trying to port the 81688-100as61ka(CYAT81X) touch screen to my Linux system.

I notice that there has a command driver in kernel/drivers/input/touchscreen/cyttsp-i2c.c.

First, check the address.

So I add the following node to my i2c device tree.

touch: 81688-100as61ka@70{
    compatible = "cypress,cyttsp-i2c";
    reg = <0x70>;
    interrupt-parent = <&cm40_intmux>;
    interrupts =  0>;
    bootloader-key = /bits/ 8 <0xA5 0x01 0x02 0x03 0xFF 0xFE 0xFD 0x5A>;

    touchscreen-size-x = <1920>;
    touchscreen-size-y = <720>;
    touchscreen-fuzz-x = <4>;
    touchscreen-fuzz-y = <7>;
};

CONFIG_TOUCHSCREEN_CY8CTMA140=y
CONFIG_TOUCHSCREEN_CY8CTMG110=y
CONFIG_TOUCHSCREEN_CYTTSP_CORE=y
CONFIG_TOUCHSCREEN_CYTTSP_I2C=y
CONFIG_TOUCHSCREEN_CYTTSP4_CORE=y
CONFIG_TOUCHSCREEN_CYTTSP4_I2C=y

But showing fail.

[    2.459429] cyttsp-i2c 18-0070: supply vcpin not found, using dummy regulator
[    2.466708] cyttsp-i2c 18-0070: supply vdd not found, using dummy regulator

How can I solve it?

Hello all,

Need help on TLE9255W configuration part for Baud rate and DLC,

In datasheet, description  it is mentioned that it can support upto 5Mbps but in SWK_CTRL_2 Baudrate Control register for Bitfield BR maximum it is given 1 Mbit/s.

Baudrate

As mentioned CAN FD Baudrate  can be configured using SPI field BR_RATIO of the register  SWSWK_CTRL_2 but not clear how to configure TLE9255W  for upto 5 Mbits/s in CAN FD through SPI.

DLC

And Same for the DLC in below image it is mention till 8 data bytes above that 4 bit value  0b1000. So how to configure for 64 bytes of data.

Thanks 

Hello ,

Please provide the Reliability (JEDEC) and FIT data of the following devices (CYPRESS SEMICONDUCTOR):

CY25811SXIT, CY25811SXCT

Regards;

Luis

Hi, I'm using ISO1H816G to isolate the output from the MCU side, but I also need some PWM output.

Whether ISO1H816G able to generate PWM output?
