Hello, I am using STM32F746 Discovery Board and want to write and read data to external flash memory . I gone through example code from STM. There is one function called QSPI_DummyCyclesCfg, I am not able to understand it completely./* Configure Vola...
Hello everyone!I'm want to use the internal reference voltage buffer of the mcu stm32g431kb as input with comparator, but when i checked the reference manual they say VEREFBUF must kept disabled because no VREF+ pin in 32 pin package!!I don't want th...
I am communicating with ad7730 (24bit adc) using atm32f103ZCT6. I try to read one of the registers of the adc but each time I receive a random wrong figure. The strange thing is that while debugging using serial wire (STLINK) everything is perfect an...
Hello,In my application I want to get the ADC voltage - waiting indefinitely until the operation completes. Will this code work ?while ( HAL_ADC_PollForConversion ( & hadc1 , 1000 ) == HAL_TIMEOUT );
Remark : I am asking this question again, since even after trying multiple times on my own, and asking on other platforms, nobody has answered it yet. I can't figure out how am I supposed to configure as slave. So sorry for that. I am not able to del...
Hi AllAbout EXTI :In some stm reference manual about "EXTI" i read some strange things : For example:In STM32f070 Ref. manual "EXTI" stands for " Extended Interrupt/event Controller".In STM32f407 Ref. manual "EXTI" stands for " External Interrupt/eve...
Hi guys may I ask for your inputs on the I2C communication. I am using STM32F103C8 MCU with 2 slaves on the I2C bus. 1st slave is PCF8574 IO expander and 2nd slave is MCP4725 DAC. I'm using CubeMX to generate my codes. What I wanted to do is use ...
I am communicating with a TFT LCD and trying to speed things a little bit. At the moment I dont have DMA library written, so I am using standard SPI mode.I configured the SPI clock as 5Mhz on STM32F407 mcu. My main clock is PLL on 96Mhz. With APB2 = ...
