Hi,I try to use MLX90393 with my STM32-F4 DISC board on SPI2. I can communicate with it, read and write non volatile memory, he responds to me.The steps that I'm doing are:Go to Single Measurment mode ( 0x3F )Send Read Measurment command ( 0x4F) Read...
Hi, I am reading the datasheet of LSM9DS1 and it says that there are two times (rise and wait) you should respectI was thinking in a sequencer IC but if we see the schematic of the LSM9DS1 evaluation board (STEVAL-MKI159V1) it does not use any kind o...
As per the question I'm trying to run a ILI9163c based display on the NUCLEO-F446RE. I'm using this library: (https://github.com/Spirit532/ILI9163C_STM32_HAL_DMA). My questions are:The library tells you to put DMA into circular mode. However, after e...
Hi, I have been able to get this sensor working, but the issue is that tap/double tap is really, really insensitive. Maybe its the plastic case of the unit, I do not know. I did the tap detection as in example:https://github.com/STMicroelectronics/ST...
I translated the matlab code to C and verified the simulated case has the same results in the matlab and C version. I'm running linux on a am3358. I'm trying to replace the simulated case with data from the lsm303ah readings and run the calibratio...
We are using the LIS2DH12 accelerometer. We want to trigger an interrupt upon motion that exceeds our INTx_THS value. The sensor could experience vibration in its deployment, therefore to prevent false positives we define a INTx_DUR value (the sensor...
The LPS22HB has an absolute pressure range of 260 - 1260 hPa. It's possible for the 24-bit pressure output value to fall outside that range. A value < 0x104000 is below 260 hPa, and a value above 0x4EC000 is above 1260 hPa. What should I do with a...
I am trying to connect this microcontroller to Unicleo, but on Unicleo it says that it cannot detect any suitable ports. However on the device manager of my windows pc I see that it is connected as a virtual com port. Is there a step that I am missin...
I used the step counter of LIS2DH12 and MMA8542 to make a comparison. I found that LIS2DH12 is a bit slow. For example, we use a step machine to test the bracelet of MMA8542 in 8 hours. The test has more than 60,000 steps, while the number of steps t...
Hello, everyone, we found that the working current is too high during the use of the LIS2DH12 sensor. The current is as high as 290ua. According to the specification, the high resolution of 100Hz is 20ua. The working current is much higher. I...
