Hi,The STM32H753 datasheet is missing the R_ADC value.On the caption of Figure 92 (p. 284) it says that R_ADC value can be found in table 183, but the value is not there.Does anybody have this value? Did the value change between Rev.Y and Rev.V?Thank...
After the validation of my CM4 application in the dual core I wanted to find a way to launch it automatically on power ON, which was not the case. The CM7 was running a touchgfx application, which was stopped during my debug session on CM4. Trying to...
Hi together, I’m trying to start a new project using STM32G031. The final decision of the MCU isn’t made yet and therefore I’m currently testing the possibilities with the Nucleo STM32G031K8 board. I’m using the onboards USB debug interface. I start ...
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...
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...
