Is it possible to extend a linux driver to support software triggers over their existing hardware interrupt ?
Hi all, I am currently attempting to extended support to the lsm6ds linux driver(https://github.com/raspberrypi/linux/tree/rpi-5.10.y/drivers/iio/imu/st_lsm6dsx) which supports the ISM330DHCX. It currently supports interrupt based buffering. I'd like...
Why does LPS25HB show wrong pressure value?
I'm using LPS25HB in my card. I can take correct temperature value but I can't draw pressure data as correctly. It show me that my Pressure is approximately 500 hpa but actually my pressure value is approximately 500 hpa. Is there any solution for th...
Resolved! How to use IIO triggered buffer?
I use ASM330LHH as Linux IIO.Source and DTS were added.We found that /sys/bus/iio also added a device.I also checked reading data in direct mode from sysfs.Therefore, I think there is no problem with the H/W connection.I want to use Trigger mode to ...
Resolved! Why do I get "There was an error loading the App on the board." when I attempt to load any of the example apps?
I am using the SensorTile.box that I just received today. I am using the ST BLE Sensor app Version 4.10.0 on my Pixel 4a downloaded from the Google Play Store. I get the same error on my Pixel 1. The blue LED flashes when the attempt to load is being...
VL53L0X Divide by Zero error in API
Hi all, Got a divide-by-zero exception whilst porting the API to the ESP32. The error occurs at line ~1960 in vl53l0x_api_core.c in this bit of maths: sigmaEstRef = VL53L0X_isqrt((cDfltFinalRangeIntegrationTimeMilliSecs + ...
Resolved! LIS2DH Raw output to Temperature conversion
I saw below topics.How can i see discussion 71915817?***The datasheet doesn't specify how to convert register (OUT_TEMP_L (0Ch), OUT_TEMP_H (0Dh) ) data to actual temperature. let's say for example if reg 0x0c = 0x7 value and reg 0x0d = 0x00 value, t...
How can I diferentiate and detect continous motion of an object from vibrations/instant shocks on an object from by using LIS2DH12 sensor?
I'm trying to detect which product is being carried by crane by using LIS2DH12 for motion detection of steel coil products. Because of the environmental vibrations or instant shocks created while handling the material in the stockyard I cannot diffe...
Resolved! If Hang up I2C interface of the LIS2DH
If Hang up I2C interface of the LIS2DH, How can i reset the device except VDD OFF/ON operation?I am considering to send 9-clocks to the SCL of the LIS2DH.
Resolved! Is there an order to change the debounce steps value at the initialization of the LSM6DSOX?
Hello,I am using the pedometer function in the LSM6DSOX. I want to change the debounce steps register value (default =10).I have changed the value to 15 but i am already seeing some delta steps = 11 (<15).Is there on order to change the debounce step...
