I'm using SPI on STM32H563 with DMA to interface to a ST7789 LCD controller. During the LCD initialization I'm using a loop to send a series of command/data bytes using the HAL_SPI_Transmit_DMA() HAL function but the DMA status never goes back to RE...
Hello everyone,i am trying to read the device unique id of my stm32h7b3 mcu, but get a bus fault on line 2: uint8_t* uid_base = (uint8_t*) 0x08FFF800; uint8_t i = uid_base[0]; Do you know what could be the problem ?
My requirement is as follows.When I power ON the STM32L4 series MCU, a string must be sent on to the UART terminal like "Power is ON". Now abruptly I will power OFF. Now at this instance, another string must be sent to UART terminal which is "Power i...
Is bit/byte swap possible for Stm32h7xx MCUs? I have looked everywhere but cannot obtain any reliable information. Some design videos are made bit swap like Phil's Lab but no evidence about that board's working, just design. My microcontroller selec...
Dear STM32 Community,I am encountering an issue with a custom bootloader implementation on the STM32F070CBT6 microcontroller. The same bootloader and application setup work flawlessly on the STM32F072RBT6, but when applied to the STM32F070CBT6, the a...
For our product we use the stm32L162VCT6D processors.To give every product a "unique" serialnumber, we wanted to use the 96-bits unique device ID.We do this also for our other products and that works fine. After producing a couple products, we notice...
Hello Everyone,I'm seeking guidance on how to connect an external Ethernet module using the RMII interface to an STM32 microcontroller. The challenge I’m facing is that CubeIDE does not allow me to customize the GPIO configuration when using the buil...
Posted on August 26, 2015 at 11:54 hi !! i like as the question , i can see the Hal_GetTick() will return the variable uWick that is uni32_t type and increment one unit when the systick interrupt happen .and will it overflow when the uint32 typ...
Confirmation of Program Operation in Release buildWe are trying to verify the operation of the program in the Release build. However, when we do [Build with Release] → [Change Debug Configuration(Select the application Release/***.elf)] → [Debug], we...
I’m working on reading an ADC that’s interfaced with an STM32L4RET6, and I’m encountering an issue with data reception when switching SPI modes. Here’s the setup:The ADC has a data rate of 8000 Hz, so I receive a DRDY (active low) signal every 125 µs...
