We have the LSM9DS1 installed in some sensors we have. We calibrate them all in the office before taking them out to measure magnetic data. When we go to analyze the data there appears to be an offset or drift in the magnetometer readings that can be...
Hi, Sometimes, when the ST bit (Self-test enable) in CTRL_REG1 set to 1, it takes a very long time(several seconds) to wait the ZYXDA bit in STATUS_REG turns into1. Is it normal?
We are so frustrated right now, we have spent days reading the data sheets, which has many errors, and the app note 3308 which is random and sketchy at best, but we are stuck with this part on a production design and need to implement the most basic ...
Is the comms protocol between the Unicleo GUI PC application and the Nucleo board documented anywhere?If so, where?The Unicleo GUI is touted as part of the "Open Development Environment", but I can't see any source code anywhere.Is it published?If so...
Hello, ST community!Recently I got a custom board from my customer to help with creating the lsm303agr driver.What I'm struggling with is the temperature sensor reading. No matter what I do, the sensor returns 0x0 0x81Here is a dump from lsm303agr AC...
The generated code may contain hundreds of occurrences of custom*, CUSTOM* and some custom file+folder names. Renaming this afterwards is cumbersome, even when using tools. Moreover, this has to be done after each code re-generation. Are there means ...
I have an STM Blue Tile and I want to send the data picked up by the microphone over BLE at a rate of 16KByte/second without using the Codec. The out of box code in BLE_SensorDemo seems to pick up the audio using MEMS microphone at a rate of 8KByte/s...
Hello,I am using ST-Sensortile dev kit and BlueNRG stack. I have to achieve @100Hz rate sending notification from sensortile to cell phone app based BLE central. I am using aci_gatt_update_char_value() api to send notification for live streaming of a...
I'm using an old IKS01A1 expansion board which is equipped with a LPS25HB pressure sensor.Unfortunately this sensor is not supported by X-CUBE-MEMS1 software pack ...
