Pressure Sensors Forum Discussions

Hi, I have a KP466 sensor on our boards.  It is a shared SPI bus with one CS going to the KP466 and another CS going to a CAN controller.  The CAN controller works fine.  I have the Vprog line tied to ground as I'm leaving it with the default settings.

Code to read 10-bit pressure:

GPIO_PinOutClear(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);

SPIDRV_MTransferB(sl_spidrv_usart_SPI_handle, tx_val, rx_val, 2);

GPIO_PinOutSet(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(1000);
GPIO_PinOutClear(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);

SPIDRV_MTransferB(sl_spidrv_usart_SPI_handle, tx_val, rx_val, 2);

GPIO_PinOutSet(PRESS_CS_PORT, PRESS_CS_PIN);
vTaskDelay(10);

uint8_t err = rx_val[0];
err >>= 3;

uint16_t press_raw = rx_val[0] << 8;
press_raw |= rx_val[1];
press_raw &= 0x07FF;
press_raw >>= 1;

There 5-bit error code is not matching documentation, it's consistently 0b10101.  The raw 16-bit value returned is 0xa97a.

Furthermore, if I try to read a 10-bit temperature with 0x4000 I always get 0x8000 back.  Any help would be much appreciated!

Hello,
I'm currently using your S2GOPRESSUREDPS368TOBO1 module integrating the DPS368 pressure sensor. Today I received the order for 5 modules, and I noticed something strange on the DPS368 sensor: the metal part on top is detached. .... Is this sensor fragile, or does this problem stem from the delivery conditions? Because in my application there are vibrations, and if your sensor is fragile, this will cause a problem.
Please find attached 2 photos showing the problem encountered.

I buy IFX demo KIT_XMC_2GO_XMC1100_V1 + KIT_DPS310_2GO *3PCS

I watch the XMC 2Go One-cl ick Setup Wizard , use the IFX tool SES2G, but other errors can't stop the sensor hub.

Instructions
1. Connect the XMC 2Go sensor, equipped with a DPS sensor, with your computer, via Micro USB cable.
2. Open the XMC2GoSetupWizard.exe to run the application.
3. The Setup Wizard will then detect whether or not you have installed the Segger J-Link drivers.
4. In case the drivers are not installed in your machine, the Setup Wizard will open the J-Link driver installer. Click 'Next' on every step of this installer and then click finish once the installation is done. Then the program will automatically move to step 5.

5. If J-link drivers are already installed this step will be executed instead of number 4. Here, the Setup Wizard will flash the XMC 2 Go board with Infineon’s firmware. The latter will act as a communication medium, between the DPS and the SES, our graphical interface for sensor data.
