STM32F479ZI CAN2 SLAVE BAUD RATE SPEED LIMIT ?

hello. i can see 500K Bps on CAN1 and i can't see this baud rate on CAN2. I use same bit timing and i can't see this baud rate. What is the maximum baud rate limit on CAN2? I attached source folders. I am waiting answer as soon as possible. Best re...

Code generated for I2C communication using cubeMX & true studio is not working

I am using STMCubeMx V5.2.1& Atollic True studio V9.2 for generating code using HAL libraries/functions . The MCU is STM32F103C8T6(Blue pill board).I am trying to write & read the one byte data from eeprom AT24CM02 using I2C communicationI used PB...

STM32L073CBT6 deep sleep

Hi, I am using STM32L073CBT6. I want my MCU go to the deep sleep and wakeup by internal RTC and one of my GPIO pin. I already read the datasheet but a little bit messy. Im using 16Mhz cpu clock, 8Mhz for LPUART ABP1 clock, 1.Right now, Im stuck on se...

Floating point emulation on DSP-L without floating point arithmetic

Hi,i am currently analyzing the FIR filter example project.Our DSP processor supports only integer numbers. Floating point arithmetic will not be supported. "The SoftFloat library from John Hausser is used to emulate floating point operations on a fi...

How the best method to save user data on flash's STM32F4 series?

Hi everyone,I'm handling project on STM32F411CEUx and I have got a trouble with save my setting into internal flash. When I used STM32F1 series, this issue was very easy because the page size was very small than F4 series. In F1, I could use some RAM...

Hi, i got question about saving multiplies values of reading in function I2C. I got sensors that needs 6 bytes to read before moving to next 6 bytes of data, so i need to save those 6 bytes in array. How to save those data in array? (in my case buffer)

HAL_I2C_Mem_Read(&hi2c1, MAX_READ, FIFO_DATA_REGISTER , I2C_MEMADD_SIZE_8BIT, &buffer, 6 , HAL_MAX_DELAY); while((HAL_I2C_IsDeviceReady(&hi2c1, MAX_READ, 1 , HAL_MAX_DELAY)) != HAL_OK);

ADC of STM32L4R5ZI controller not able to read below 60mV, Vref = 2.8V and ADC resolution is 12bit

Below 60mV controller unable to produce ADC output

HI I'm using stm32f303cbt6, I'm facing issue with RTC . RTC module configured with 24hpurs format Suddenly rtc time (hours) changes to 38hour or 26hours. presently using Hal driver API's with atollic.
