The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
HI, i am using two timers in interrupt mode by setting 100khz frequency for each . one timer interrupt is for my power factor calculation and other one for current calculation. But the problem is when it comes to while loop. once my code enter int...
I would like to respond to the falling edge of a square wave that is of 50% duty cycle, running at 1us pulses (500kHz). This signal comes from my LA2016 logic analyzer (has PWM outputs) and is fed into PE4 of my STM32 discovery board (STM32F407VG MCU...
I want to cause a 60ms delay within a callback. I am sending data using a UART and the serial protocol requires certain delays. I would prefer not to change the Systick priority so that means the callback has a higher priority than Systick and HAL_D...
Hi,I would like to provide / route a Timers external Clock Signal to CH1 pin, but only if CH2 is in Active state.So that it acts kinda like a AND Gate.Is this possible? If so, how? Is there a sample somewhere I can have a look at?greetings and ...
Hello, I need to control a high frequency pwm with a low frequency pwm on a F407. I have used the gated method described in RM0090, it mostly works, but since the master pwm control the enable of the counting, the output of the slave timer can be le...
For instance What pins can UART1_TX come out on? Or what peripherals are attached to PA5?I would think there was a table somewhere. I have looked in the RM0390 Reference manual but they say Alternate Function 0 - 15 but do not say what the alternate ...
Hi there, this is a question referring to one old post, as I do not know if any solution was found for it or if anything changed after these years:https://community.st.com/s/question/0D50X00009XkY1mSAF/detecting-current-channel-in-adc-interrupt-callb...
Hi,I am playing with STM32H747 dual core. I used the example code in DISCO. I am able to bring up the two cores and light up the LEDs from both cores without problem. HSEM also works fine.Now I am trying to write data to SRAM (0x10000000) from one co...
Hi,I would like to design a debug LEDs for UART/I2C communication (STM32F103), the purpose is just to see wether the communication is working or not, through a LED, here is my schematic, My questions are : 1) what is exactly the output voltage on Tx ...
I need to use the HRTIM for it's 10 phase synced outputs, but at a lower speed than what pre-scale and period can cover.I have TIM1 producing the base waveform I want, and now I need HRTIM counts to be based on that, instead of the CPU clock. I found...
