Pressure Sensors Forum Discussions
Need verification of the schematics of Barometer before we start the production
I would like to buy the "SP4XDEVKITTOBO1" development board (https://www.infineon.com/cms/en/product/evaluation-boards/sp4x_dev_kit/#) but unable to find any order information and already check on eTailers site for this evolution board.
I really appreciated if someone could please guide me into correct direction ASAP to place an order for this.
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
Dear infineon, do you have or do you have in roadmap a similar barometric absolute Pressure sensor with high accuracy like the ST LPS22HH ?
Thanks a lotShow Less
First, sorry for the wrong forum assignment, but I didn't find the suiting forum.
We are accessing a DSP310 pressure sensor via SPI interface. The sensor's registers can be read, so I obtain expected values reading registers:
0x0D => 0x10 (Product ID)
0x08 => 0xC0 (default MEAS_CFG)
But I cannot write any register, which would be necessary to start a measurement. For a very simple approach, I tried to enable FiFo, (setting register 0x09 to 0x02). But when I read back the register, the value is 0x00 (default). I took care for the cleared high bit during write access. We are using 4-wire SPI.
The SPI-interface was only used by DPS310 in our first HW Setup. We needed another SPI device (MEMS), so we connected it to the same CLK, MOSI and MISO PINS (CS of course on another PIN than DPS310_CS).
For the MEMS, it is possible to read and write registers without any modification of the interface program.
So, the occurring question is, is there a special mechanism to "unlock" DPS310 registers for SPI-write? Is there anything else that could be tested on why the write access fails?
