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 everyonei try to Synchronization two timer together in master / slave modei have a problem when i enable another timer interrupt ,once of two sync timer freq was changed!!you can see in my logic analyzer resultthis is my code:static void InitTimer...
Hello, I want to connect my FLYsky radio reciever to stm32f446re for which an rc signal in required.The Rc signal has duty cycle from 1500 us to 2000 us.But i can not understand how to do it with the help of timers.If you have a code about that plea...
Simple program. Trying to make a push button turn on an LED. I have connected on pin of the push button to 5V and the other pin to the STM32F411E-Disco board directly without any resistors. The anode of the LED is connected to a 330 ohm resistor and ...
Hello, I am using stm32f429i discovery boards for spi communication. I am using HAL libraries, trying to send dummy data, but my DR register is not getting updated, , I am using atollic truestudio, I kept the clock of both boards same can anyone help...
I have enabled interrupt for BOFF, EPVF and EWGF.When e.g. sending with error the very fist time TEC becomes = 1, all flags remain 0. However I get an interrupt any way - every time I get a send error. Eventually i get flags set as REC/TEC gets large...
HIi have (hopefully) set up a three channel ADC with DMA and a Timer to get a sampling frequency of 100kHz. I am wondering if somebody could t Hake a quick peek on my code to verify that it is correct. The HLCK is maxed at 216MHz, and TIM6 has a peri...
I am planning to make a custom PCB using the STM32F777NI micro-controller for that, I have to make the schematic for the same to make the PCB. I can't find the symbol for the micro-controller for the schematic. Where I can find the symbol of the all ...
Dear all,to explain better, what I have is an external memory connected to my stm32f4 MCU, in order to communicate with it I have to pass through the FMC. The external memory is an FPGA.What I would like to do, if it is possible, is to first iniziali...
Help find the answer. I want to run TIM2 in trigger mode. If you connect ETR1 to Vdd, then the current at input ETR1 will be 45 mA. If you connect it to Vdd through a resistor, then the timer does not work. Where can I find a diagram of the correct c...
