Hello,I'm managing a Wifi modem using one of the USARTs of the STM32L475.Modem is working fine when sending and receiving AT commands and data, but I'm not able to receive URC's.I only receive URC's when they come 'together' (very close) to the answe...
Hello.I am trying to save variables to flash when there is power loss that i detect using PVD. I got PVD to work correctly and trigger interrupt at 2.9V, but now i cannot find the right examples to see how to save the variables quickly to flash. I h...
Hi,I am migrating my project from STM32F778AI to STM32H747XI and I have some issues regrading EXTI interrupt on M4 core.I use custom board with J-link programmer.I have simple button with hardware pull-up and I configured pin to be EXTI11 on M4 (enab...
HiI use STM32U5 SPI2 in Salve mode to only receive data，and the data-size is 16Bit. Because the rate is very fast, I use the DMA_LINKEDLIST_CIRCULAR mode combined with the DMA half-full interrupt solution.When I used HAL_SPI_Receive_DMA() to start SP...
I'm writing firmware for stm32c011f4u6 using Keil5. I downloaded and checked an example about ADC from the homepage, but I only found the code that uses DMA. Is there any example of using ADC with Polling instead of DMA? Also, I need an example for m...
started using STM32H573 recently, having issues with Flash Edata when reading data from EData area, which crashed at HardFault_Handler() with STM32H573I-DK. But it is running fine with NUCLEO-H563ZI for the same job.The example project “FLASH_EDATA_E...
Hello, I'm new to the forum and I want to ask about how to make the I2S connection between an STM32F441RETx and an SSM2604 Audio CODEC.Here are the corrections:My doubt is on how I should connect the Serial Data pins from the CODEC to the MCU. Should...
Posted on June 24, 2016 at 07:52Circle OS used to be a GUI software for the STM32 line of microcontrollers. I am looking at building my own object handling software from the ground up, but I need some guidance so I wanted to reference Circle OS.Does...
I'm implement IAP in Nucleo-H745ziq.So. when i into application then cm7 trigger(boot) to cm4.cm4 can't boot in keil but in stm32CubeIDE can boot. SET_BIT(RCC->GCR, RCC_GCR_BOOT_C2);
HelloIn my case, I am working on the project using the SPL provided by ST.It uses the STM32F429II series, and the compiler is running on IAR.I have a demo code for USB FS on the STM32F103 series, can I get a demo code for SPL USB FS on the STM32F4 se...
