Hi,I been trying to set up a stm32F405 mcu usb host with a hub onto which 4x stm32 device is connected. I would use these 4 devices to send data to the main mcu periodicaly at 50Hz, and to have the data transfer syncronised from the 4 devices to be o...
We are working with STM32H7-Disco (Dual Core). Can we only wakeup M4 core and put the system in dstandby1 mode.I mean, if we are in Standby mode and we use a tamper interrupt from a button, our system reset M7 core and M4 core, but we want only wakeu...
Hi,This is my first post by the way, I do have stm32f401 and I am trying to use the stand by mode , I want to detect the wakeup reason, is it RTC or reset button, in case of RTC I will do one thing and incase of reset button I will do something else,...
So, I'm having strange behavior regarding the serial number of my board with an STM32F091.I have a Python software that sends a packet on the serial port every 100 ms. I have initialized the serial port on the ucontroller with the same settings as ar...
Even Arduino boards have schematics available, why is ST doing this? Do you want to wipe out the few users who buy the development boards? :thinking_face:
Hello;I have the STM32H747I-DISCO card CPN: STM32H747I-DISCO, FG: DK32H747/SAT1, and on the MB1166-A03 screen A225300631. The problem is when I try to test the card with the BSP example, I encounter the following problem:I saw in the forums regarding...
Once I posted the issue about 2 PWM outputs synchronize.https://community.st.com/t5/stm32-mcus-products/2-pwm-outputs-is-this-possible/td-p/587654 Now every 1st time after power on (or CPU reset if connected with IDE/Programmer) it works exactlly syn...
Hello. In my project, I would like to printf float type variables such as: float t_degC = -45 + 175 * t_ticks/65535; float rh_pRH = -6 + 125 * rh_ticks/65535; printf("t_degC = %.2f \n",t_degC); printf("rh_pRH = %.2f \n",rh_pRH); Ini...
Hi , I m a student starting to learn STM32 for your final year project i would like to learn more about how to use FreeRTOS, using STM32CUBEIDE GUI to configure FreeRTOS and if anyone can advise any website, code , tutorial I can learn from? thx.
HiI am trying to make an analog synthesizer, and for this is using a STM32G431 with some 8-channel DAC’s (connected via SPI) for generating control-voltages for the VCA’s and other circuits.I would like to use the SPI with DMA, and have looked at the...
