Sending large amount of data with USB
I'm currently facing a big problem. I've an MCU (STM32L4) connected to an SD card (SDIO) which stores tons of data (5Gb) from a microphone (ST MEMS). I need to send this data as fast as possible from SD card to my PC. With a serial port this is to sl...
Resolved! LSM6DS3 pin capacitance
Hi,I am using the LSM6DS3 with I2C at 400 kHZ. I would like to know the pin capacitance value so as to calculate the value of the required pull up resistors. I was unable to find this in the data sheet.Thanks
Resolved! LSM303AGR date code?
Hi,I would just like to know the date code on the LSM303AGR on our PCB Board. So far I have not found any document to interpret the date code. The markings are 636 AGR.Regards,Markel
LIS2DE12 pull up resistor values
Hi,I have been using the LIS3DH successfully but I want to go to the LIS2DE12 because it is smaller and only does what I need. I have wired up a STEVAL-MKI175V1 board to a 3.3 v Arduino close to do some initial evaluation. I can't get it to respond a...
Dont getting data from max30100 connected to NUCLEO F401RE
Hello,I connected the nucleo F401RE to max30100 using i2c level shifter tca 9406 https://www.ti.com/lit/ds/symlink/tca9406.pdf?ts=1596413075744, and I am only getting the adderss of the sensor but no data.I also tried to add 10k resistors and got t...
VL53LDK Index address ?
Hello?I have a question.I am developing using MCU.I am using VL53LDK to measure distance.I want to know the I2C Index address.Index address:?How many byte?How can i calculation?Thank you.
Use LIS2DH12 detect sit or stand
Hello everyoneWe are designing a wearable device. It's worn on the waist. We want it can generate an interrupt when a man sit down or stand up, so that we can know a man is sitting or standing. It's a low-power device, wake up every 3 seconds.Now, we...
LIS2DH12 fault
Hello everyoneOur device use lis2dh12 to measure the acceleration. We tested 10 boards. But we find 3 board work abnormal. These three board are all facing up, the reading of x axis and y axis should be 0, and z axis should be 1g. But the readings o...
Resolved! which spi mode is supported in iis3dwb sensor and why it fail to read who am i register at first attempt after reset?
I am exploring iis3dwb sensor with stm32f401 nucleo board.i go through the data sheet but not find any information which mode this sensor supported?so i tried with these 2 setting , hspi3.Init.CLKPolarity = SPI_POLARITY_LOW; hspi3.Init.CLKPhase = SPI...
