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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on March 30, 2013 at 22:15Hi, In our system, I have to be able to update the application code. Therefore I believe I need to copy the application to memory location 0x8000000 and then jump to this location...basically a small bootloader of so...
Posted on March 30, 2013 at 17:19Hello, I need to connect 4 Ultrasonic sensors to STM32f4. Basically I need to measure the pulse width on their output. I tried to configure an interrupt with TIM5 (32bit counter) for 4 channels and at each interrup...
Posted on March 30, 2013 at 09:21I have experienced with AVR MCU-8bits programs. When I was begin to AVR MCU, there is an official reference that prepared by Atmel itself for developer to understand what register should be initialed in order to have...
Posted on March 29, 2013 at 20:12Hello!I search evrething about this hardware I have bought (whith two probes & a TFT screen with TouchPad (400x240) who can be an oscilloscope 2 ways. I have no software to work with and I have not found it on intern...
Posted on March 25, 2013 at 11:19Hi everyone!! I'm working on my very first project as engineer with a friend and colleague. We bought th eval board with the f4 and f100 series microcontroller on. We tested our code on both of them and everything's ...
Posted on March 29, 2013 at 13:03Hi, i'm a new user of this board and i have a (maybe trivial) question. Searching on the web i found that there is a ''ITM_SendChar()'' instruction that could be very useful for me, but i can not view its result on m...
Posted on March 29, 2013 at 09:23 Hello, I have been trying to use multiple usarts with receive on interrupts. Some part of the communication takes place between a PC Com and STM, while some communications is taking place with STM to another STM...
Posted on March 28, 2013 at 21:34 hello dear forum, I write 2048 to STM32F4 DAC, it gives 0.83V instead of 1.65V if I write 4095 it gives 1.65 V instead of 3.3V the output of DAC is input to an OPAPM amplifier I mean it i...
Posted on March 28, 2013 at 11:12Hi, My application requires a bootloader that loads an application into a FLASH device. I have created two different applications: bootloader. start 0x08000000 A FLASH application. start 0x08001000 if i ...
Posted on March 26, 2013 at 17:15The Reference Manual states ''The internal PLL can be clocked by the HSI RC or HSE crystal.''Is it possible to clock the PLL by feeding an external reference into OSC_IN?If there is no signal present at OSC_IN will t...
