STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I found out in the errata of STM32G070 MCU (page: 12, section: 2.11.1) that: in UART mode with oversampling by 8 or 16 and with 1 or 2 stop bits, the received data may be corrupted if a glitch to zero shorter than the half-bit occurs on the receive l...
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...
How can I set in Keil MDK, used to stored some parameters such as soft version,manufacture date and so on at a block of（such as a page） STM32G4‘s Flash memory， thanks.
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...
Hello all,I am working with STM32-Mat/Target and currently facing an issue when placing a receive block with External mode enabled. The error is the multiple definition of 'HAL_UART_RxCpltCallback' and 'HAL_UART_ErrorCallback' which is called in both...
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...
