Hi,We are working with the LPS22DF pressure sensor to be used in our device adapting a 3.3V system and have encountered issues related to the interaction between VDD_IO, VDD, and the I²C bus. When VDD_IO and VDD are connected to the same 3.3V supply:...
Hi, I am using MotionFX with BlueCoin, for a solution that can detect vertical movement within 2 meter range with high precision. I took the ALLMEMS2 example when I logged linear acceleration and gravity, it showed some unprecise values likelinear a...
Hello community,I have an application where I want to implement STHS34PF80 for detecting people PRESENCE and MOTION with a range of 3 to 4 meters. In the Datasheet it is stated that it is possible without using extra lenses. Although, I am struggling...
FIFO_CTRL4 is 00A1 in hex , 10100001 in binary FIFO_CTRL3 is 00AA in hex , 10101010 in binary fifo_status1 is 00000000 fifo_status2 is 00100010 FIFO DATA OUT TAG IS 00100001 I have already set LSM6DSO like this but no data is inside the FIFO Must I...
Hello,I am using MotionFX on STM32BlueCoin device. I tested values of linear_acceleration and gravity from MotionFX library, and I have very strange bias on produced values, although I try to feed perfect hardcoded data to the library.For example I a...
Hi,I am developing a product that can be installed in either a horizontal or vertical orientation and uses the LIS3MDL as the source for a compass..The PCB is common so the LIS3MDL will be in one of 2 orientations.In a horizontal position everything ...
Hi, I want to detect a shock with the H3LIS331DL and its interrupt on threshold level. I used it in normal mode and an ODR of 1000Hz. The shock in my testbanch is : I want to know what is the minimum of time when the duration is setup to 0 with my ...
Hello, I'm using the LIS2DW12 on my own board.Consumption seems a little high to me. In the datasheet I found a value around 5.5µA and I obtained rather 45µA.The configuration is as follows:- ODR 50Hz- FIFO in continious mode with INT1 enabled- Full-...
Hello,I am using STEVAL-STWINKT1B development board and I can write and read sd card using setting to SD 4 bits Wide Bus and FATFS.If I add on STM32CUBEMX as middleware FREERTOS I can't read the SD in fact I get back FR_NOT_READY when I execute the f...
Hi, I'm trying to decipher the inner workings of the fsm configuration on this sensor. While the an5904 application note features an example of configuration on page 42, things take a turn after the 21st step. The following step selects page 2, and I...
