STM32F411 Discovery's PB6 not working as I2C1_SCL
I have an STM32F411E-DISCO board and I am facing a problem with the I2C1 Peripheral. 1. I configured the I2C1 (PB6 & PB9) to interface with the CS43L22 Audio DAC on the Discovery Board and it gets stuck at waiting for the SB bit in I2C1->SR1 register...
Resolved! Nucleo-f446RE: external power supply while using UART and STLINK virtual comport
HI EveryoneI am using Nucleof446RE board for uart communication through usb cable which is also my power supplyIs it possible to use external 5V supply for MCU and use USB cable only for uart communication or any uart to usb converters are needed to ...
I2C weird behavior, SDA come high before SCL
I was implementing i2c on the stm32f4 to read the as5600 magnetic encoder. Everything ran perfectly for a while, then the I2C got stuck, I check and see that after the start generate, sda transition when the scl still low. I checked many times and t...
Different patten when same output frequency at differernt pin. (NUCLEO-H563I)
I tried to set the SPI CLK to 20MHz at VDD=1.8V, but there was no output signal at PB13. When I change to 5 MHz it returns to normal, but the waveform seems to have been filtered by the low-pass filter. Finally, I set it to 2.5MHz to make it work st...
Use SPI with STEVAL-IDB008v2
Hi,I'm trying to use spi on STEVAL-IDB008v2 board I want to wire spi flash dev board, after reading the documentation I'm not sure but if I want to have spi on bluenrg2 I have to desolder R64 and R63 resistors ? EDIT : it's seem 1-2sel and 3-4sel are...
is it possible to use 2 pins on same EXTI?
Hey,I want to read an EC11 encoder without disturbing the main loop, so I decided to use interrupts.Can I connect both pin A and pin B of the encoder to PA1 and PB1, and use only EXTI1 to map the switching events to the same interrupt routine?
