LSM303DLHCTR - Peak Current Consumption Issue
Posted on April 02, 2018 at 19:18I'm using an LSM303DLHCTR in an application where I'm reading its X, Y and Z magnetometer values once per 20 ms, and have noticed that the chip seems to consume 10 mA or more of current from its 3.3V supply (VDD pin)...
HTS221 Cal. Coeficients
Posted on March 27, 2018 at 09:03Hello,I implemented the software for the HTS221 in my project and all is working. But what I find strange is this, some calibration coefficients are negative!H0_T0_OUT is -2H1_T0_OUT = -11728Although they are negativ...

Voltage drop when connecting IKS01A2 to B-L072Z-LRWAN1
Posted on April 03, 2018 at 18:10So the B-L072Z-LRWAN1 board is configured to be powered through the 3.3V pin by removing SB6 and R26. Furthermore, the ST-LINK was disconnected by removing SB28, SB29 and SB37. When testing with some example code and...
How does LIS3DH configure automatic sleep and arousal?
Posted on March 16, 2018 at 11:40 I want to be able to when the device has detected movement, LIS3DH to wake up from sleep mode, and at a higher rate to detect more than I get a set of threshold, then the interrupt, to remind me of the MCU. I trie...
