Hi,I want to debug a code for USART ISR Handler. The code is working fine. But If I debug, I am getting this error. I am using keil uvision.Cannot access target. shutting down debugging session.Why this error is coming. And how to over come this? I a...
For the most of the peripheral (e.g. ADC1) it is obvious, but what is withLL_APB2_GRP1_PERIPH_SYSCFG or LL_APB1_GRP1_PERIPH_PWR? Does the voltage regulator work, if PWR peripherals clock is disabled?
I have a STM32L072KB microcontroller and want to combine two analog signals (they represent a kind of "quadrature encoded signal" with a 50% duty cycle) into one "combined digital output signal", which have the doubled frequency (for my purpose the d...
Hello Everybody,I was thinking about a flexible way to implement a µs or ms delay function with a free running timer as tick source. One of the biggest problems that comes to my mind is the overflow problem when the timer wraps around, so that some c...
hello. I have a question using uart(115200, 8, 0,1) in stm32f103vct6.huart3->gstate have been changed hal_busy forever In an unspecified situation and system is halted. I use true studio compiler. and In debug mode at that time, systick interrupt ...
It seems like we have run into a delicate timing difference of the I2C in STM32F042 and STM32F072. Identical code (coming from the exact same source file) for I2C works fine on STM32F042G4U but has a problem on STM32F072V8T.When doing larger I2C tran...
The value of the repetition counter can only be 255 maximum. However, I have to generate over 255 pulses, which I must be able to adjust. Is there still another possibility to generate 65536 pulses without using interrupts?
When I trying to run PWM on PA8 I get no PWM at all. The pin just goes high and I can't understand why. I used HAL example code. The cpu is running at 16 MHz and here is the codeHW_TIM_PWM_Set(4000, 70); HW_TIM_PWM_Enable(); HW_TIM_Delay(1000); HW_TI...
Hello I am using STM32F779BI controller.I have to write data to external flash(MT25QL256ABA8ESF) using QSPI .I have writen code but main issue it stucks after write enable commandany solutions for this ,or any samples examples , reply meBest RegardsD...
I'm intending to use PC13 as an output to drive the onboard LED, but at some point in my program the PC13 pin begins outputting a 4.4 khz signal with pulse width that varies from 0% to 100% back to 0% and keeps repeating that pattern at approx 4 Hz. ...
