STM32 MCUs Products

I want to stm32g4 fdcan communication with stm32f105 canbus . But It does not interrupt because the bits do not match. How can i send and read message with fdcan - can?

Concerning the RTC peripheral: Can I convert SubSecond Register value to millisecond during a Shift Operation (SHFP=1) ?

RM440 Rev 5 says : "SS can be larger than PREDIV_S only after a shift operation. In that case, the correct time/date is one second less than as indicated by RTC_TR/RTC_DR"Low Layer Driver documentation says: "==> Seconds fraction ratio * time_unit= ...

Hello, Is there any way speed up clock out frequiencies MCK and CK while keeping WS clock out frequency constant at I2S communication(STM32f446)?

My main concern to speed up double MCK and CK clocks frequency while keeping WS frequency constant at the I2S communication. But when i double up the I2S frequency all of the frequencies doubles up. For e.g.;When WS is 43.71kHz, CK = 1.4MHz and MCK =...

Trigger I2C DMA RX transfer with LPTIM1 at each (1/200)s

Hi,What I want is mostly in the title, but I'm confused on how to configure LPTIM1.This is the STM32CubeIDE config of LPTIM1 :1) I'm not sure I understand why I can't set the autoreload value (which the reference manual states is a 16-bit register) i...

Is the HAL libraries for CAN-bus the same for all STM32 microcontrollers?

Hi!I just have written a SAE J1939 library for CAN-bus. Yes it works.But I got a request from someboy and he asking me if I could make this so it not only fit STM32F3 series. It need to fit all STM32 series.https://github.com/DanielMartensson/Open-SA...

How to implement I2C communication with a sensor like AD7147-1?

I followed this example that does i2c communication with TMP102 https://www.digikey.in/en/maker/projects/getting-started-with-stm32-i2c-example/ba8c2bfef2024654b5dd10012425fa23.In the case of AD7147-1, the module can read up to 13 sensors and I'm try...

Pending and disabling of interrupts in STM32L431RCT6

I am using tim6 with a period of 140 ms. In another interrupt that has a priority greater than tim6, I am disabling the tim6 interrupt. But sometimes even after disabling that interrupt, tim6 update interrupt occurs and after that, a variable is corr...
