Being here just 30 seconds.I have two questions, where the first one is about using a typdef union{} in other files, see my code here // a.h typedef union{ float vf; unsigned char vuc[4]; }fc4; // a.c fc4 vfc4a; // b.c #include "a....
Regarding the ADC, with Gain Compensation, Offset, and Hardware Oversampling:Reference manual (RM0440 Rev 5) page 647 and also page 664 say:"Offset correction is not supported in oversampling mode. When ROVSE and/or JOVSE bit is set, the value of the...
On an STM32F0 I would like to read a digital signal using the input filter. I configure an input (e.g., TIM1_CH1) in input capture mode and I properly set the input capture filter (IC1F) to remove noise of the input. Also, I need to detect both edges...
I dont understand why this is a option for the mux clock selector. css is a great feature so i didnt find reasons to not enabling.In which cases i should not enable it?
We are using "STM32G473VET6" in one of our application requiring 7 pins from different ports to be mapped as external interrupt (EXTI) vector. But as per reference manual document "RM0440" section 9.3.8, "All ports have external interrupt capability....
TIM1 is configured for complimentary PWM for three phase motor control.PWM switching frequency is 4khz i.e. 250us, but i am finding that PWM time is getting varied from 244us to 248us. sometimes 252us.Is it some calibration issue or what? Can anyone ...
HiFigure 120 in the reference manual RM0008 shows the control circuit in normal mode. It shows an update event using the Update Generation bit (UG). See attached figure.I am curious about the CNT_INIT bit, which is a pulse one clock cycle after the U...
Hi,I have a board containing an STM32F415RG and another board containing an MCU from another manufacturer. Both boards are supposed to communicate with each other using RS-232 transceivers. The communication is running at 9600 baud and working well f...
I'm using STM32l152 and use TIM5_Ch2 for generate pwm .My target frquency pwm is 2.85 KHz .I using these parameter:clock frequency = 32MHz htim5.Init.Prescaler = 6; htim5.Init.Period = 100; I measured pwm on oscilloscope and I measure 2.85KHz with 5...
Hello, I'm trying to understand the peripheral to peripheral transfers. I'm pretty sure my setup is correct but it's not working and I don't think I understand enough to know what to look for to troubleshoot. For my test I simply have uart1 rx connec...
