Hi,We are using LPUART port of the STM32L4R5 controller for communication with BLE for that we would like to use RTS/CTS signal.How can i control/check the RTS/CTS signal?Is it possible to control/check the RTS/CTS signal through the software?Please ...
We are using an STM32L452, running directly from an HSE crystal at 8 MHz (i.e. no PLL), using the SDMMC peripheral with an SD clock of 8 MHz, and DMA for transferring data to and from SDMMC.We're also using the SD, DMA and FATFS library code generate...
Posted on April 12, 2018 at 02:23I am using an STM32F446ZE Nucleo Board which does NOT have an external HSE clock. From CubeMX I set the clock input from the HSE and after in the clock configuration I set the system clock to 180MHz.https://i.stack.i...
Hello,I tried to compile the simple "Blink" sample with the Arduino IDE, but I get always an error:Board Nucleo_64 (platform stm32, package STM32) is unknown Error compiling for board Nucleo-64.I installed the latest Stm32 Cores (1.3.0) via the Boa...
Dear forum,I am using ST STM32F103R8T6 MCU for my medical project, i referred the hardware design guide to design the MCU schematics, now i have question in my mind that how do i deal with unused pins?should i connect 10K resistor to ground? or shoul...
I am receiving a sequence of addresses, with each valid address I make the change in the MCU register of the next address to be received, but I see that on the MCU STM32F303 you need a delay between words.
I am wondering if you can pin swap the data pins ( withing byte lanes) without any software consequences? If their are any is it easy to resolve?I am also wondering if you can pin swap the address pins at all and if you do can you do it without any s...
I am working on project in which we are using STM32F103C8T6 and I have one development board called blue pill and also have st link V2.But I don’t know where to start which are the softwares are required for STM32 development. I have searched on the ...
I save config data (40 bytes total) in a dedicated flash sector (in my case sector 3)with the application running on the board. Before I write the sector is erased.I write several words with multiple calls of HAL_FLASH_Program(FLASH_TYPEPROGRAM_HALFW...
Hi,I'm trying to set the PLL output to 48MHz on a STM32F030CC:HSI = 8MHzRCC->CFGR PLLSRC = 0 (PLL input = HSI/2), PREDIV = not divided.PLLMUL = 12;should give (8MHz/2) * 12 = 48MHz but instead I get no clock output on MCO.Using the MCO output I have ...
