There's a sensor applied to the I2C as a slave. Also on this microcontroller there's a communication running on the UART-Interface in blocking mode. If the UART has to transmit a huge amount of data, it seems that the I2C (also blocking mode) can get...
i am using stm32f103rb i think i have found a bug i am trying to use i2c1 on pin port b 8 and 9 for that you have to remap i2c1 in afio mapr register i have done that but in debug session i note that the bit never get set i have attached code and deb...
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...
