STM32 MCUs Products

Can anyone suggest the supporting BLE module to interface STM32F4 controller.

Hai, We are planning to develop a custom board with STM32F413ZH and STM32F413VHT6 so we are looking for a ST BLE module to be interfaced with these controllers.So can anyone suggest me which is the correct one and good feasibility of BLE stack util...

I am using STM32F407vg, i wrote a code for ADC while debugging value is not updating no errors as well in the code. i connected a 10K potentiometer to PA0, i checked with DMM no issues. I am adding my code snippet please let me know the mistake.

/* Includes ------------------------------------------------------------------*/ #include "main.h" #include "stm32f4xx_rcc.h" #include "stm32f4xx_gpio.h" #include "stm32f4xx_adc.h"   /* Private variables ----------------------------------------------...

Can CAN slave acknowledge CAN master message and vice versa?

A CAN device when sending a message needs an external device to acknowledge the message for successfull transmission. A device will not acknowledge its own message. What about CAN master and slave in a single e.g. the STM32F303? Can the slave acknowl...

reset timer count value

i wrote a program and i want to turn on the led after passing a 500 and 750 , 1000ms.i use out put compare and use active on mach timer mode.but it only work one time , i realize that i should reset my timer and count value but i don't know how?plea...

sir my question about the RTC when i wakeup in that standbymode mode my rtc value is the reset and take somting garbage why ?

how do I get the samples of the IC STM32H757AII6?

The product is not in stock on mouser and arrow. Also, I couldn't find it on ST store. Can any one please help me?

Variables in domain D2 are not initialized ... here's why

By default, the variables in the D2 domain (SRAM1, SRAM2 and SRAM3) are not initialized by the linker because DATA_IN_D2_SRAM is not defined in the file system_stm32h7xx.c.DATA_IN_D2_SRAM is used by SystemInit () which is called by the STM32H7xx_Star...

STM32F103RCT Two rotary encoders on timers 2 and 3 Nothing works!

Hi! I am trying to get two encoders running on my STM32F103RCT6, I had it previously accomplished on STM32L152RCT6 and everything worked, but I needed to change the MCU, to something with a DMA to Peripheral mapping. I am using exact same board layou...

Weird problem with UART
