Hi all,I have some problem with LCD1602 + pcf8574 (I2C) and STM32F107pcf8574 operate as SLAVE.I setup i2c in CubeMX and used this tutorial ( https://controllerstech.com/i2c-lcd-in-stm32/ ) to operate LCD, but I failed, then I write a I2C bus scanner ...
I have a simple and trivial question.I read the registers of TIM3 in encoder mode in polling and so far everything is ok. The encoder is a normal panel encoder with knob.I want my reading of the encoder register not to fall below a limit (this exampl...
Hi, Can someone help me find the minimum voltage Vcc of stm32f103c8.Lowest voltage that will allow for maximum clocks frequency. And wont interfere with usb (pullups at data line to vcc).And adc.2.4 V is minimum when using adc. But will it run at ...
Dear ST community,we are planning using stm32f0 as driver for our X-Y control Unit. with please see the attachment.The requirement is to update the application of stm32f0 via SPI.And we would like also to use the parts of the HAL library.Is those two...
Hello,I am interested in providing an external (high-speed) clocking source to the board - provide 10 MHz clock signal from an external signal generator, via I/O port.As i read in page 25 of STM32 Nucleo-144 boards user manual, I made properly the so...
I accidentally overwrote the FW loaded by ST for P-L496G-CELL 02. So I cannot access the voucher code. Is there any way to retrieve the voucher code?
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 ...
