Resolved! Need a clarification on NRST_MODE functionality
I'm using a STM32G031J6 MCU in my project and i need to use the reset pin as a GPIO. From what i read on the reference manual this can be done by setting the NRST_MODE option bit to 2 (GPIO). However the issue i'm facing is that if the reset pin is h...
Touch water sensing?
Hi! Can I use touch sensing embedded in stm32L432 to sens water level or just water presence? Contact or contactless (capacitive).I want to use this to sens water presence. Connect a long (5-10m)wire to touch PIN and another to GND. Or just single ...
Hi, I am going to use this STM32H7 CPU at my board and I want to know what the GPIOs state during power up, configuration and reset.
are the GPIOs at HI-z? pulled up? or Pulled down?this is very important to me, I don't want to enable any circuit at start up.

Hello All,We design a circuit with STM32F030F4.And when I checked the current consumption of the circuit , I saw the curent consumption is changing by the time.It moves like decreasing for some time and increasing suddenly after that decreasing for s...
STM32 Cellular Library for Quectel MC60 to send REST Packets
I have connect STM32H7xx device with Quectel MC60 GPRS Modem via UART. Instead of working with several AT commands to send the packet over SSL layer. I would like integrate with any open Cellular library which can used to enable PPPoE over Serial to ...
Hello everyone, How can I get number of clock cycles to execute these assembly instructions ?
I'm using stm32f429 Discovery board and I want to know number of cycles required to execute this part of assembly code .ldr r3, [pc, #64] ; (0x8001228 <TIM1_UP_TIM10_IRQHandler+120>)ldr r3, [r3, #0]ldr r3, [r3, #36] ; 0x24ldr r2, [pc, #64] ...
Resolved! How to enable GPIO EXTIx interrupts?
Hi,I need to enable interrupts for pins PJ0, PJ3, PJ4 and PJ5. Why these pins? Because they are connected to the ARDUINO connector (CN5 and CN6) of the STM32H7474I-DISCO board and they all seem to be all free. I have the initialization code (Hopefull...
