I recently bought a nucleo board for a project im making. I have in the past used 8 bit AVR chips but I want to step up to STM32. My project is some switches, leds, a DAC and an ADC. One thing that is common to all these elements is a serial data out...
I combined 2 examples. USART3 I/O and SYSTICKS timer.When I receive a USART interrupt the Systicks stops working. There is a endless loop of interrupt calls of USART3. So I assume I didn't acknowledge the interrupt correctly. Only can't also find it...
Hi, I am using STM32L071 which has Low Power UART (LPUART) Communication. I want to try LPUART at the maximum baudrate, but what is the maximum value of LPUART baudrate ? is it the same as UART in generally ? based on datasheet, the maximum baudrate ...
Hi, I have some problem with UART. im using stm32l152Vb uC... in that, im suing standard peripheral library...I configured two uarts (UART1 and UART2) both of them are working in normal mode. I want to send data from PC to mcu-UART2 and after receivi...
Hi everyone,I'm developing a new one project using STM32L031K6T MCU.It's mandatory to use a simple low cost device for massive production.Now flash memory is almost totally consumed.I'm tring to use compiling optimisations to reduce program dimension...
I am trying to set RCC->PLLCFGR |= PLLSRC after setting RCC->CR |= HSEON and waiting for HSERDY to be presented.I have tried this while with and without RCC->CR PLLON set.The device will run fine from either HSI or HSE, and I verified the speed is th...
Good Day! A stm32 micro newbie here.I just want to ask regarding my issue on my SDMMC.Currently working on accessing microSD through SDMMC interface with FatFS. When I disabled the "Use dma template" I don't have problem accessing the microSD. I have...
Hello,I have a PCB with STM32F427, since a few days, I am having more and more problems with the MCU.As stated in the title, every morning when I restart my board it is locked with RDP level 1, PCROP and R/W protection on all sectors, as stated in th...
