STM32L452xx: Memory mapping calculation

Looking at the datasheet of the STM32L452xx family, it's noted that SRAM size is 160K.The memory mapping on page 86 notes the address range from 0x2000'0000-0x2028'0000.But 160K is 0x2'8000 and not 0x28'0000, which would make the range from 0x2000'00...

Missing counter using TIMER input count

Hi all, I'm using nucleo STM32 L4R5ZI .Using systick 120Mhz as clockand set timer 2 , channel 1 as TIM_TS_TI1FP1 (Trigger and rising edge)Then, using int count = __HAL_TIM_GetCounter(&htim2); to sample the count for every 1ms. Input 40KHz . By right...

using PWM function in STM32F302R8 nucleo board. [ SOLVED] I can't start PWM function . most of my code has been made by using Cube. I see nothing in ouput PC2 and PF0 for TIM1 chanel 3 and 3N.

I am French.There is now more than one week that I try, see youtube and some comments on forum. I need your experience for solving the initialisation of a "simple" PWM.Thanks in advance.Joëlhere under my code. in the main I have launch : PWM1_CH3N_se...
