do you have a ready-made example of keyboard implementation, I need to connect a keyboard to stm32f105, but nothing works, please give a ready-made example with a keyboard, on standard libraries I always just hang on HOST_CTRL_XFER, but why this happ...
Sometimes the Verification step of DfuSe fails , while the application is flashed correctly and can run without problems after the verification fail message!!!what is the reason for this problem and How can I overcome it?
my PWM wave as center align mode.Thank you
Hi all, how are you?. I'm doing a project with a STM32F103C6 (it has 32KB flash) and I had to activate optimization options to not run out of memory, right now the optimization options is -Og. After activate optimization a function that I have to kn...
Hi, I am facing an problems that I have never seen before with local variables being allocated at the same addresses of global ones. In the attached image I show an example of a local variable with the address of another variable in the STEmwin libra...
Hi,I want to configure the FMC such, that it should just write 8 data bits in a VERY SIMPLE way - without any switching.I use the following code:#define RAM_D1_FMC_SRAM3(off) __attribute((at(0x68000000+off))) //global variables: int iDebugFMC; int ...
Hello, I'm looking to use Timer and DMA to drive a WS2812B LED with a STM32H7. TIM8 Ch2 is connected to the LED. I would like to explain what I understand so that its clear and I can get it working.A half word transfer from a memory location to the C...
https://github.com/STMicroelectronics/STM32CubeL4/tree/master/Projects/B-L475E-IOT01A/Applications/ProximityHi,I was going through the example of promixity sensor of B-L475E-IOT01A board in the github stm32l4cube repository. i compiled the code and d...
I have a photo interrupter attached to an interrupt port powered by the 3.3. volt supply.Every now and then, there is a burst of activity on the 3,3 volt line which cause havoc on the interrupt line.img_0933 shows the output of the photo interrupter ...
Hi thereI am trying to configure a GPS receiver chip (MAX2769C) with an stm32f446re MCU using SPI in half duplex master mode. The chip is expecting a 32 bit word (4 bits address and 28 bits data). This is on page 21 of the attached datasheet. My firs...
