Need help !!! I want to make 3 delay functions which works guaranteed delay in nanoSecond, microSecond and milliSeconds using Timer.
What i am currently using to achieve my goal.Few Details :1: STM32F103C8 Blue Pill2: CMISS core Library3:Datasheet, Reference Manual and Programming ManualI have attached two files. Which give you some idea that how I want to make These 3 functions. ...
Enabling a PWM kills ability to set state on some GPIOs
I am working with an STM32F777. I need to enable both GPIOs and PWMs (which ones is configured at run time by the application). Right now I'm seeing that some PWMs kill other GPIOs. For example if I turn on a PWM on TIM4 CH3 (PB8), it kills GPIOs on ...
Resolved! Odd behavior in assembly busy wait cycle
I am preparing the labs for the undergraduate embedded systems course at the university where I work (the University of Milano-Bicocca in Italy). This year we will change the hardware and we will start using the STM32 Nucleo F767ZI boards. I am a tot...
Resolved! Variable Color Generation with PWM signals and RGB led.
Hello everybody.I tried to develop a simple application, using a RGB led to produce variable colors in a continous way along the time and I still not have succeeded completely. Let me explain what is happening:1) I used STM32CubeMX 5.3.0 to configure...
Can not open source input file: No such file or directory
Dear friends,I get a silly error " No such file or directory " in Keil IDE while I've already added the file path to include path directory of the compiler.This error happens only when I add lwIP source files to my project. And what's surprising is ...
Resolved! STM32L433 LL SPI sending too much data (16 instead 8)
Hello. I need ability to send only 8 bit at the time. And I can't figure-out why I can send it, it keeps generating 16clocks no matter what LL_GPIO_ResetOutputPin(GPIOA,LL_GPIO_PIN_4); Delay(0x8); while((SPI1->SR&SPI_SR_TXE)!=SPI_SR_TXE); ...
STM32H7 SDMMC IDMA write multiple blocks error
Dear all,I am working with the sdmmc lib from STM and i am trying to get it working in DS (Default Speed @25Mhz) with a CARD_SDHC_SDXC, CARD_ULTRA_HIGH_SPEED sd card.When I write multiple blocks with the IDMA for the first time it’s no problem and ev...
STM32F411RE UART not working with IAR debugger
I am currently learning to work with stm32f411re. I use PA9/10 as TX and RX with baud rate 9600 and 1 start 8 bit word and 1 stop without parity. I connected PA9/PA10 with FTDI to my PC and i am trying to send from serial terminal. Trying to do this ...
