What is exactly a peripheral reset on STM32H7
Hello,It's not clear for me what a peripheral reset (registers RCC_xxxRSTR) is doing. I didn't find the details in the reference manual. I assume it resets the internal state machine of the periph, its FIFOs, but for example does it also reset its co...
How to program the Option Bytes on a G0?
I'm trying to program the option bytes on an STM32G0B1 but it keeps timing out at the end of the program sequence and never actually succeeds, no matter how many times I try.I enable the Flash peripheralI (successfully) unlock the flashI (successfull...
Resolved! How can I use timer (TIM22) in STM32L031K6 to get interrupt on OC on channel 1 and generate PWM signal on channel 2?
In my application I want to use timer to turn on LED for around 300ms and simultaneously generate PWM signal of freq 2.7kHz (for buzzer) on PA10 pin. Is there any way I can achieve this?(NOTE: I have already used TIM2 and TIM21 timers. TIM21 is also ...
Resolved! Why HAL_I2C_Mem_Read returns only 0?
Hi,I am using stm32f1 and HUT21D sensor (Temperature and humidity sensor). The sensor use i2c for communication. I am using IAR and cubeMX.For cube: I used default setting for i2c.For IAR: I shared the main.c below.Can anyone help on why only get 0.#...
Resolved! STM32f072R stuck at 16mhz (RESOLVED)
HI i got a problèm on an stm32f0.after a reset the µC is at 8mhz but i'm only able to climb to 16mhz when i want to go to 48MHZ , did someone have idea of where does the problem come from.the µc are not new because i work on protoboard and i cant cha...
how to used i2c dma tx circular mode.
Hello, We want to i2c dma circular mode but in this mode i2c is working once times. when our data finished we want to again again transmit.
STM32G4 - HardFault on Voltage Drop
Hi!I currently am trying to investigate random hardfault errors if i connect some addon board to my current project. What is happening is: On connection, VCC drops to 1,8V minimum, while being under 2,5V for ~ 2us. The result of this is either a rese...
STM32F373 SDADC configuration mystery, how should it work
I'm trying to use SDADC1 and SDADC2 to convert four signal (2 each) and I'm not getting good data. I'm using CubeMX to do the setup and I've selected Gain=1 Single-Ended zero reference for all inputs so I can convert a signal range of 0 to VDD on all...
