Hi,did anyone try to connect to the gyro (L3GD20) on F303Discovery board over SPI?I have a problem even with reading the WHO_AM_I register:My code is generated with Cube and I added the following lines:퐮퐢퐧퐭ퟖ_퐭 퐝퐚퐭퐚_퐰퐡퐨퐚퐦퐢, 퐚퐝퐝퐫퐞퐬퐬_퐰퐡퐨퐚퐦퐢;퐚퐝퐝퐫퐞퐬퐬_퐰퐡퐨퐚...

Hi,I created a new project using ready HAL Libraries on STM32F3, I get an weird error (expected an identifier) on the following line in the file (stm32f303xc.h): __IO uint32_t TR; /*!< RTC time register, Address offset: 0x00 *...

Can anyone tell me the difference between those functions:HAL_I2C_Master_ReceiveHAL_I2C_Mem_ReadThe problem with HAL_I2C_Master_Receive is that it accepts too few parameters (hi2c, DevAddress, pData, Size, Timeout).I don't know how to tell the memory...

I started a new project using CubeMX for my STM32F303-Discovery board and try to get the Acceleration values but without success!In my main.c, I do the following:i2cBuf[0]=0x20;//CTRL_REG1_A ODR = 1344HZ | Normal Mode | XZYeni2cBuf[1]=0x97;HAL_I2C_Ma...

I started a new project using STM32CubeMX for a STM32F303VCTx, and used all the default options, and then configured the Timer3 for the all 4 channels as PWM ouptut (as in the snapshot).I open the project using uvision V5.26 and change the main.c onl...

So I did exactly as explained, and I get some plausible readings, the only problem is with the scale!My sampling rate is 1/2500us = 1/2.5 ms, so I should multiply each gyro reading by this time interval and then accumulate the value to get the curren...

Thanks for the reply, with the 2 values I was meaning the range of the readings.So even if the board is stationary, then the reading on Y is continuously changing between 500 & -500.Do you mean then the physical reading should be exactly as follows:1...

@Eleon BORLINI could you please help me?I am really confused about how to correctly read the angular velocity using the function L3GD20_ReadXYZAngRate!!First If I let the line 396 in l3gd20.c without any change, then angular velocity on X=[-1100, 230...

@Eleon BORLINII am using the HAL driver to read the gyor values, I think there is a mistake in the file l3gd20.c on line 396.Here the raw data should be divided by the sensitivity, but it is multiplied.Is this a mistake or I don't understand it well?...

@Eleon BORLINI Thank you again for your help and explanation.I think I can do further and of course the only means is by increasing my sampling rate, but of course there is always a chance to loose some rotation info in case the vibration of the boar...
