Hello,I am integrating multiple sensors from ST, all of which are connected to a central processor via I2C. Occasionally, I find that the LPS22HB is unresponsive at boot up. When the central processor attempts to read the WHO_AM_I register, there is ...
I am bit-banging since my CPU doesn't have native SPI compatible with the LIS3DH.To initialize the chip, I write:0x57 to Control Register 1 (DATARATE_100HZ, XYZEN) {see pic CR1Write.jpg}0x80 to Control Register 4 (BLOCKDATAUPDATE, SCALE_2G) { see pic...
My application hopes to detect objects on a flat surface (e.g. table). I hope to place the VL53L1X in a vertical plane, close to the horizontal table top. Then I hope to be able to ignore reflections from the table itself by using the RoI feature. I ...
Dear ST hello,I have a question about the bit field,I am using the stm32F429 discovery board, and I am working on the gyroscope Mems.if I declare a union like this:typedef volatile union { uint8_t All; struct { uint8_t Yen:1; /*X axis enable*/ ...
I have the STEVAL-MKI224V1A with the LPS22DF pressure sensor. This is attached to a STEVAL-MKI109V3 motherboard.I downloaded and installed the UNICO GUI version 9.14.6.0 The GUI app opens as expected and I select the "Environmental Sensors" on the le...
Dear Sir,Here set XL ODR = 104 Hz and Gyro ODR = 104Hz, routing XL data-ready to INT1, Gyro data-ready to INT2, respectively.Interrupt mode is set to pulse mode here.Do reading XL register and gyro register on INT1 and INT2 for clearing data-ready i...
Hi all!I have a problem with transmition/receiving more than 8 bytes of data between two STM32 MCUs via CAN-Network.I know, it is impossible to transmit more than 8 bytes of data via basic CAN Bus.I tried to create Command messages System.CAN Master ...
I bought a VL53L0X sensor, and download a example(it named vl53l0x-arduino-master) about it from github. And i found that the program stays consistent in the while ,as shown in the picture.So i want to ask the question is that why the 0x83 address r...
Hi,I developed an application that uses an STM32L452 and MP34DT06J, with SPI and DMA. I don't have an external clock on the MCU so I'm using the internal one. Regarding the storage, I'm using an external Micro SD driven with SDMMC.Since I've more sen...
