STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi all, I tried to configure the clock to run at 32MHz and I was using Systick to toggle the LED every 1 Sec by configuring the Systick reload value by 32Mhz -1. But, Somehow toggling is not happening for exactly 1 sec, and also used a logic analyzer...
Hi,I am trying to interface FM18W08 FRAM from Cypress using FMSC in the STM32F303ZE board. I feel stuck as there are no good guides on how to interface. If anyone has previously done it, please let me know.I am mostly curious about the pin connection...
I am using micro switches in my system with the GPIO EXTI. I would like to detect only the press of the switch, but the interrupt was triggered on both press and release of the switch. The interrupts were even triggered twice on each press and releas...
Hello everyone, I am new to the world of STM32 and am trying to get a bit familiar with the topic. Unfortunately, I'm stuck with the code to read the UID from an NFC tag. The code itself has no errors and is uploaded to the microcontroller. Unfortuna...
I am trying to get a SPI port up and running on an STM32H745BI chip but after configuring the port and starting the transmission I never see any signals on the pins and the port never gets an End Of Transmission (EOT) high signal. Startup code is lis...
Hello,The setup comprises a keyboard connected to the Host-configured USB port of an STM32F4 dev board and the keyboard is configured with the following two HID Report Descriptors: 0x05, 0x01, // Usage Page (Generic Desktop Ctrls) 0x09, 0x06, ...
It is not recognized as a USB device. What did I do wrong or miss?IC: STM32F103CBT6 1. Is the distance between USB D+ and PA12 (Pin 33) and USB D- and PA11 (Pin 32) long?The distance from USB D+ to PA12 and USB D- to PA11 is approximately 35 mm (1,38...
Hi,i am trying to investigate the behaviour of the ADC when measuring a value, where the ADC is triggered from a timer source.In the manual it states, that when the ADC is clocked from SYSCLK or PLL "P", then it would be faster, but when clocked from...
Hello,Hope you all doing well..!! I am using two microcontrollers i.e., for transmitting data I have to use STM32F407VET6 and for receiving I have to use STM32F407VGT6 also I have to connect MCP2551 CAN Transceiver. I am transmitting data from one bo...
Hello everyone,I have been using for a long time the stm32L496ZGT6 in a customized PCB with an uSD card module. Never had any problem interfacing the card. Due to the shortage of supply during the pandemic situation I bought a couple of stm32L552ZET6...
