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 Everyone,I have Nucleo-H723ZG and I managed to configure CAN to work there but only sending messages. I am not able to get anything in RX Buffer.I configured CAN like:hfdcan1.Instance = FDCAN1; hfdcan1.Init.FrameFormat = FDCAN_FRAME_CLASSIC; ...
Hello,I hopefully selected proper category, forgive me if not.I have the following question.There are files like for example /CMSIS/device/stm32l053xx.h(or similar files for other devices)which include useful definitions of addresses of all the perip...
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...
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 ...
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] ...
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...
Hi,I'm started to develop on the NUCLEO-14 F746GZ board recently. My question is: it's possible to read input from device (in particular NFC reader MOD-RFID1356MIFARE) through USB CN13? I tried but the device is not powered. Thanks for your support
Hi everyoneI have a system that uses a STM32F205 to sample on a signal at 2MHz. I wanna generate a signal that indicates the sampling times of the ADC as im battling with some frequency differences in my system. Interrupts are sadly not an option as ...
STM32L432I'm using interrupt mode HAL driver and the i2c slave responses successfully for many transactions but then will randomly hang. Here is the code I'm using, its fairly simple.volatile uint8_t i2cbuf[2] = {0, 0}; static void MX_I2C1_Init(voi...
