Posted on November 04, 2017 at 22:25 Hello everybody, I use two interrupts in the STM32F051K4 MCU. There are EXTI0_1_IRQ and EXTI4_15_ORQ. With EXTI0 will be PA0 used (Hall sensor) and to EXTI4_15 are PB5, PB6, PB7 Pins (user keys) conne...
Posted on November 04, 2017 at 16:24Dear *,I have some questions about the STM32H7 series:1) As i see the MCU can work from 1.6V to 3.5V power supply. a) if i set the VDD to 1.8V than all the I/O and interface pins are 1.8V logic ? b) is it possible...
Posted on November 05, 2017 at 15:14I'm using STM32F407 Discovery-1, I use USB CDC to send and receive data from terminal. Everything ok but issue that I need re-connect port to transmit and receive data, but i remember that when i used STM32F407 Di...

Posted on November 03, 2017 at 16:43Hi, I am using Keil and STM32F769I-Eval board.I try to readout a sensor with an external ADC (AD7980). The signal I try to convert runs with 200kHz.I generate with a timer every 5us an interrupt. With the interrup...
Posted on November 04, 2017 at 20:18I'm using my stm32f446 nucleo to build a weather band radio with SAME decoder. If the weather is good, the only emergency alert broadcast is the required weekly test. Debugging my code when I have only one oppor...
Posted on November 02, 2017 at 22:28 I am having some debugging issues with Keil uVision5 eval (free) version. Now the STM32F030F4P6 has 16K bytes, and when I compile my program, it is approaching the memory limits. Below is the code size: Progra...
Posted on November 03, 2017 at 06:51Hello,I am using an STM 32 F401 Nucleo and i want to send numbers from PC via UART.For example I need to set the frequency and amplitude.Can some one help me to provide the code?Thank you in advance.
Posted on November 04, 2017 at 11:17I want to transfer some data between two microcontrollers via 16 lines of data and one clk line.(Based on STM Application note AN4666 ''Parallel synchronous transmition using GPIO and DMA'').I use two STM32f407 fo...
