STM32 MCUs Products

I get stuck in an interrupt after calling SPI transmit.

Hi!I have STM32F373VBTx and I have set pin PD3 as EXTI3 where PD3 call this function when the PD3 gets a falling edge. PD3 is labeled as TS_IRQ in STM32CubeIDE 1.6.1/* Callbacks for external interrupt */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)...

I have no idea which framework to use. You have too many. Which one will meet my requirements? (listed in details)

I want to code in C++, at least std=C++14, preferably C++17 or better.I do not want any drag and drop stuff. Nothing.I do not want to be forced to use code generators.I want a framework that other people actually use and write code for.I want a frame...

CANBUS peripheral of the STM32F746ZG works with a MCP2551 transceiver..??

Hello, I have a big doubt. I have a STM32F746Z microcontroller and I want to use the CANBUS peripheral connected to a MCP2551. The MCP2551 datasheet specifies that the communication lines with the microcontroller work with 5V voltages and the STM32F7...

STM32F446RE - RTC Wake Up from Standby Mode

Hi everybody, I have some problems related to wake up procedure from Standby Mode using RTC Alarm Interrupt. When the Alarm time is reached, I have a continuous autonomous wake up from Standby Mode. Could you please help me? Here is the code I provid...

I wqnt to connect three slave, do I need three SPI blocks from uC? But this SPI slave will be access simultaneously. may be CS can be shifted by few clock for each slave.

I am using the Nuclo-h745ziq.I want to connect three slave so can I require a three spi blocks or can i use one spi and I connect it three spi.Please help me.

Is there a pin compatibility of dual core MCU with STM32H743BI ? I would like to upgrade my MCU to dual core.

STM32G071 HSI RC (internal RC oscillator) accuracy // RC oscillator use for UART

Where is the accuracy if the HSI RC (internal oscillator) specified? I cannot find any data. There seems to be some presentation slides but this is no a valid specification. I need the worst case accuracy over the complete temperature range. I have r...

dual core data share

HI I'm working on STM32H745. I'm tiring to understand share data with 2 cores. Can you please post a program ?

TIM1_BKIN Behavior When Fault is Detected

Please I want to Know how TIM1_BKIN for example in STM32F103C8T6, behavior when it detects fault and when the Fault disappears? What is the approximate Time it may take to turn off the TIM1 PWMs Channels ant when the fault disappears, does it delay ...
