Resolved! Timer counter does not stop when it reaches the ARR value
Hi,I am developing a program with the nucleo STM32G474RE that passes the ARR,CCR1,CCR2 values to TIM2 after some measurements made with another general purpose timer.However something weird occurs since when I look at TIM2 registers the ARR,CCR1,CCR2...
Resolved! Is it possible to disable SBK (break frame) on STM32G474RB on Asynchronous mode UART?
I have been looking in the documentation and break frame gets mentioned but cannot find whether is possible to disable the SBK.
STM32H745 Disco - schematics?
It seems as of April 2021, the schematic was removed from the user guide.Why? Where can I find the schematic?
LL DRIVERS SET ONE PULSE MODE
I'm trying to generate 3 pulses using the One pulse Mode on the TIM1 with the LL drivers. I'm using an STM32F401RE.I only get one pulse regardless the value I set for the repetition counter. I have done lot of research on the internet but I couldn't ...
Why do my ADCs channels read the same signal within a sequence of regular conversion while the pins are not linked? (STM32H747)
void ADC_Init(void) { /*******************Horloges**************************/ SET_BIT(RCC_C2->APB4ENR, RCC_APB4ENR_SYSCFGEN_Msk); //SYSCFG clock delay(1000); SET_BIT(RCC_C2->APB4ENR, RCC_APB4ENR_RTCAPBEN_Msk); //RTCAPB clock delay(1000); ...
Bit definition for FLASH_ACR register seems to be wrong
Hello everyone,I have been trying to program STM32F106C6T6 using CMSIS.I came accross FLASH LATENCY programming where i have to configure 2 wait states in FLASH_ACR register.As per Reference Manual, RM0008, I am seeing that value 2 will be used to co...
Bidirectional GPIO Functionality
I need to integrate an STM32G071RBT into an existing design with a parallel bidirectional data bus. Based on section 7.3.10 of RM0444, I believe I should be able to do this by configuring my GPIO as open drain. In this configuration, if an external...
tickless wake from low power mode with 32 bit / 32768 Hz resolution
I'm new to the STM32L053R8, and I'm trying to emulate a configuration I've used on other ARM M0+ systems. Ideally, I want to maintain a 32 bit counter (physical or virtual) clocked at 32KHz so I have ~30 uSec resolution with a ~131K second roll-over...
