STM32 NUCLEO-F767ZI rs485

Hi i want to communicate between board with stm8 and board with stm32 the stm8 have rs485 communication bus does STM32 NUCLEO-F767ZI have build it in or i have to buy some extension?

Please can anyone show me a register that identifies the family "STM32F10x" of the MCU? I'm not interesting for a Unique device ID register "U_ID".

Hello,I would need a register that systematically identify the family type of the micro "STM32F103ZDT6".In the reference manual there is the Unique device ID register, but it gives a unique identifier to the chip, I would like an identifier that woul...

FDCAN STM32H7 Detect message loss in overwrite mode?

Is there a way to detect a CAN message loss in a RX Fifo when in the overwrite mode (so an overwrite?)

SDRAM Module Tester based on STM32F429

Hello everyone,I need to build a system to test a bunch of existing memory modules built around 512 Mbit SDRAM chips (4 chips each for total of 256 MBytes). The attached schematic shows the original design of the memory module and how it's connected ...

I am looking for an easily available MCU to do a simple analog readout through a 32position mux and CAN-Bus connection. With my very limited understanding I looked at the stm32f0 series. But some of them are hard to find. Is there a better option? Thanks

Multi-channel on STM32F429DISCO not working

Hello,I use a STM32F429DISCO REVE01 with a MCU STM32F429ZI.I have to use the ADC. On PA0, I connect a sensor with an amplifier and it's work, but when I want tu use ither channel like channel 1 with PA1 pin, that's not work, my value is around 0.Why ...

How to implement the program for PWM generation in stm32f051c8t6tr

I working on stm32 microcontroller, I want to generate the pwm signal for stm32f051c8t6tr mcu. I have assigned my prescalar as 48-1 and counter period is 1000-1 in order to generate 10KHz frequency.My code is TIM1->CCR1=50;HAL_TIM_PWM_Start(&htim1,TI...

Debugging the MCU on a NUCLEO-H7A3ZI if 1.8V is selected?

Dear all,It seems like I actually broke two Nucleo 144 with a H7A3 and H723 after I tried to debug the MCU with the on board debugger and after switching the supply voltage for the MCU to 1.8V (no connection from debugger to MCU possible, even not wi...
