Hello All,I was wondering if it is possible to clock another STM32 MCU (STMF031) using the single existing crystal oscillator that is currently clocking the main MCU (STM32F334). It could really save me space, power, cost and another clocking source ...
My stm32 mcu is a i2c slave device. When master sends the address on the bus, I want stm32 to respond with a known byte upon address match. How can I do that?I want to send different type of data with different size to the stm32 slave. How can I make...
Questions about STM32F479BIT6If the MIPI circuit is unused andThe following pins are NC,pull-up,pull-downWhich terminal treatment should I use?Target Terminals119/120/121/122/122/122/124/124/125/126/127/128/
I am learning on using the STM32L431CC FLASH memory to store data after the microcontroller loses power. From compiling through Keil, I get:Program Size: Code=34316 RO-data=1228 RW-data=364 ZI-data=1908From the above, Is it correct that only 35Kbytes...
I'm using 'stm32f103rc'.I connected the button to the GPIO PIN.If the button is still pressed, the HIGH signal will continue to occur.So, how do you detect how long the HIGH signal has been pressed?Because when the button is pressed for more than 0.5...
On my stm32g0 mcu there is no eeprom. So, I am using internal flash to save one byte user data to retain it between power cycles.I am doing it the following way,Add Data section in memory in the linker scriptMEMORY { ...... DATA (xrw) : ORIGIN =...
Hi there,I'm designing an application with an STM32L412K8 and I don't use ADC, OPAMP or COMP. The datasheet (DS12469) says:VDDA shall be 0 to 3.6 V if ADC, OPAMP, COMP is not used (general operating conditions table 21).When the functions supplied by...
Hi,We are using STM32F746ZET6.we have to calculate input frequency on 5 pins from 40khz to 0.01hz.currently we are using 50 micro seconds timer and at every timer interrupt we are processing frequency calculation based on the polling of the pin stat...
Hi all, I've recently been teached about how to manage streamed data in this case for managing commands, then my code is like the following explanation: I've programmed the uart2 to receive the streamed data byte to byte and I've been storing it in a...
How do I obtain one? Cube isn't helpful -- this isn't a filter parameter. I need an MCU with built-in backup battery domain for the RTC. I don't want to build anything external and the design must not be capable of powering up the core from the batte...
