Pressure Sensors Forum Discussions
I am working on the pressure sensor (DPS310) for my study.
The time resolution of the sensor is around 4Hz which I would like to develop.
Do you guys have any idea to develop the time resolution of the DPS310?
It is ok to lose the accuracy a little bit after I fix the time resolution of the sensor.

If you have sample code for RF communication between SP40T and CMT2219B or code to read sensor values of SP40T, please let me know.
Thanks you so much!!!
Hi Dears.
I want to read parameter from sensor by sending command through out I2C for the SP370 (900 kPs) In programming Mode.
I can read Temp and Voltage of Battery correctly. But for check Flash_erase Status, i can't get back right CRC from sensor!you can see my signals in below pictures.
For checking status i send the FLASH Check Erase Status and wait for 40ms and get the answer!!
I get the this Chars :{0xFF,0x03,0x5A}! what is that wrong?
The some thing is weird! All commands from my side that have no CRC (like getting voltage or temp or status) give me back right but in some command that i have to send CRC with, the answer is wrong?!
Thanks.
Show LessDear 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 lot
