Hello!I have never before worked with a microcontroller so all of this is very new to me. I am using the MC-kit IHM07M1 with the NUCLEO-F302R8 as a control board. I am trying to implement chaotic PWM in the microcontroller like in the figure attached...

Hello!I am having trouble when connecting STM32 to Motor Pilot. I am using F302R8 control board and IHM07M1 as power board. I can see the port in Decive Manager and it says it is port COM5, but when I connect through COM5 from Motor Pilot I get the m...

Found the problem. For some reason one element in//Logistic map x[i] = mu*x[i-1]*(1-x[i-1]);becomes negative and after that hell breaks loose and it start wandering off to infinity making //Timer frequency f[i] = fc + (2*x[i] - 1)...

I also added HAL_TIM_Base_Start(&htim1); HAL_TIM_Base_Start_IT(&htim1);to main(), after enabling TIM1 and interrupts in TIM1. But the problem remains. The chaotic pulse is only active for 5-6 s and the motor is not running.

I added __HAL_TIM_ENABLE(&htim1) and __HAL_TIM_ENABLE_IT(&htim1, TIM_IT_UPDATE) in main(). I also added LL_TIM_ClearFlag_UPDATE(TIM1) and R3_1_TIMx_UP_IRQHandler(&PWM_Handle_M1) to the interrupt handler.And now I acutally get the desired output, ...

I have configurated the board as the manual says, the message is still there. USART2 is set in the "Connectivity"-category and MotorControl is set in the "Middelware"-category (maybe this is the problem?).

Thank you, I found it in the data sheet of L6230.

Changing CRR for three channels in TIM1 everytime ARR is reached?

"Port Open and try to configure the board"

What type of tranistors is used as power switches in the P-NUCLEO-IHM001? I found that for some other ST-family there are MOSFETs but can't find any information about the transistors in the STM32. If they are MOSFETs, are they NMOS or PMOS?
