Resolved! STM32G4: First ADC samples are not correct
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...
Resolved! Reading non zero value on HAL_ADC_GetValue when input is connected to ground STM32G030F6P6.
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 ...
How to get day of week by RTC? if you had no idea so I had share my function.
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...
UART Timeout
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...
NUCLEO-H503 Timer
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 ...
Resolved! STM32L475RE Connection lost
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...
Where can I find an example USB Host (external PHY) and HUB class support?
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 ...
SRAM ECC Check problems
I am having trouble with SRAM ECC check on an H7 MCU.When i enable the registries the system trigger contiuouslly the ISR for a detected error and the status flags/registries are empty.Also initializing the SRAM at startup dosen't solve the problem.T...
STM32L47 Stuck During Reset
Hi all,I am currently experiencing some weird reset behavior for my STM32L47 chip. Due to a non-optimal combination of HW the chip resets from time to time, and I am assuming an ESD issue being the reason for this. As long as the resets are recoverab...
