Why transmitting data in STM32 I2C slave is not working

I am using STM32L4R5ZI as a I2C slave. From I2C master I am getting first command and On my slave device I am sending the response but the slave code hangs there(and it makes my master device to reboot automatically). Please provide the necessary inp...

How to communicate MCP39F511 Power Monitoring IC with STM32 to read RMS current and voltage values?

I am trying to read the RMS current and voltages values from a MCP39F511 IC by using STM32, I was wondering if there is anyone who is also working with MCP39511 IC and has a way to read those RMS Values from MCP39F511 by using STM32!

I cannot make the CAN TX interrupt work (CAN RX int does work, though):

Using: stm32l476 on the ST eval board, I set the CAN INT as follows:   if (HAL_CAN_ActivateNotification(&CanHandle, CAN_IER_TMEIE | CAN_IER_FMPIE0 | CAN_IER_ERRIE |         CAN_IER_EPVIE | CAN_IER_BOFIE) != HAL_OK)   {      /* Notification Error */  ...

UART receiving problem (using interrupts)

Hello everyone,I am facing a issue I can't explain.I am migrating a code from F1 to F2.I am using UART4. If I only use this peripheral I can send and receive data and everything work well.Then I am using a the TIM6 to have a 2ms counter.In the IRQ of...

Is it possible to copy the code stored in the internal or external flash to the internal SRAM and execute it from SRAM ?

Can I use MCU's internal oscillator when communicating with GPS and cellular modules?

Can I use MCU's internal oscillator when communicating with GPS and cellular modules? I want to avoid connecting external crystals for the MCU since they generate noise, extra components, extra costs, and on top of that require PCB design constrains ...

Timer sample code for buzzer on STM32L432G

Can you please share me timer sample code for STM32L432G board.I have Sensortile board and would like to interface buzzer, so I need to add timer code to get timer cb to toggle the required frequency to get the proper buzzer sound.Also please suggest...

Hello. We use stm32f405 and voltage 1.9 V. At this voltage, timer 8 does not generate PWM at a frequency of 12 MHz. At a voltage of 3.3 V, the generation works.

Using HAL and CubeMX. APB2 72 Mhz. The timer prescaler is 0, the period is 5, the duty ratio is 50%. How to solve this problem?

HTU21D sesnor with Nucleo-L152RE

I am newbie to use Nucleo-L152RE board. I have a HTU21D-Temperature & Humidity sensor which used I2C interface to read the temperature data.So, with using the STM32CubeMX I have generated code for STM32L152RETx chip with UART2 (debug purpose) and I2C...
