I`m using an encoder on STM32G4 series to set speed of the pump motor. I have values between 0 and 100. I set autoreload value as 200. I`m looking for the solution to avoid counter autoreload. I mean, when counter goes to 200 - it stays 200 instead o...
I want to scan 14 channels of adc1 in scan mode using interrupt. I need it to be with interrupt not DMA and I know how to use DMA so please don't tell use DMA! :DThe problem is that HAL_ADC_ConvCpltCallback runs only once! I will attach my code here....
I would like to know the connector CN1 the daughter board for stlink v3I am attaching an image for reference. Kinldy anyone share the part number
Summary: I am sampling the internal voltage reference 5 times using DMA with the ADC set to continuous mode with LL_DMA_LIMITED. I know about the errata that says to ignore the first ADC value, but the other 4 values only become consistent if I use a...
Hello, I am working on STM32G030F6P6 microcontroller. PA0 pin is configured as analog input, 12 bit resolution. I am reading non zero values when PA0 pin is connected to ground. I tried on 3 different microcontrollers but each microcontroller ADC ...
I had use RTC calendar in STM32 with ext-oscillator.but I was surprised when I try to set date which it's don't set day of week by itself.and they also had no function to find day of week too.OK. I make this function follow Sakamoto's methods calenda...
I have been using the HAL_UART_Transmit() method to transmit data . In this transmit method I should give the timeout parameter since it is a blocking function. My doubt is what is the unit of timeout parameter?(i.e. milli seconds or micro seconds or...
Hello.I am using the NUCLEO-H503 board, and I would like to verify its speed-related specifications accurately.I am attempting to toggle a GPIO pin using the Timer NVIC whenever the HAL_TIM_PeriodElapsedCallback() signal occurs.Currently, my board's ...
Hello together,I am currently trying to program a STM32L475RET6. But I have the problem that when I connect the programmer and click on connect, a connection can be established, but it disappears after only a short time with the error "connection los...
Hi, I'm rethinking the board, to use USB external PHY, but I will need support for the HUB class, where can I find an example of use for STM32F4?I found a presentation by Roman Ludin (September 2014) where the document says that the library does not ...
