Design of Battery operated STM32L0 Hardware
I want to design battery operated hardware with stm32l0 series. i want minimum 5 years of battery backup for my project. please suggest me the best hardware along with stm32 and battery management solution also
Resolved! STM32F051C8 TIMER1 PWM NOT WORKING?
HIstm32f051 config with stmcubemxbut, timer1 and timer2 and timer3and16and17 not working for pwm generationonly timer15 good workwhy????
STM32F769I-Discovery CAN BUS
I work with STM32F769I-discovery board. in CubeMX CAN bus interface are not available to be selected. Can someone point me to the right diretion of initialising CANBUS?Many thanks!
Why low voltage on VBAT hold the read command on UART port
I experience a problem when the capacitor is fully discharge. When the program try to read from a UART port it stall on the read command and the application will not continue.If I put a delay before the read for the time that it takes the capacitor t...
Resolved! PWM input falling edge capture behavior
Hi,I'm following RM0390 reference manual's PWM input mode example for calculating frequency and duty cycle for incoming PWM signal. Basically I'm using TIM1's CC1 for capturing rising edges and CC2 for capturing falling edges. The question is that is...
What is the proper method to interrupt/signal that new information is ready between core M7 and M4 in an STM32H7 processor?
I am looking at the STM32H7 reference manual and STM32H745 code examples to determine how to transfer and signal new information between the cores. Currently I see two possibilities: Shared memory and a hardware semaphore/interrupt or shared memory a...
Resolved! Activating TIMER PWM mode with CMSIS. Need help!
Hi all! I'm fighting witn CMSIS, and now I'm triyng to start a timer in PWM mode. The MCU is a STM32F303CCT6, and the timer I want to use is TIMER3, activating a led on PA6. I didnt modify any clock, so I supose the MCU uses the HSI clock at 8MHz.Thi...
