STM32F746-Disco board; Windows 10, STM32CubeIDE 1.7.0, empty project, only CMSIS and nothing else.I'm writing an interrupt-based UART transmit driver with ring buffer on registers for the sake of learning (no DMA, that will come later, after I grow s...
Greetings, I have a question regarding the IBIS model of STM32U5A9 family. in the setup of any pin there is model parameter that has to be selected. There are several models such as io100m_ls_xx_xxx. what exactly those models mean in terms of actua...
I have question about STM32H7 QUADSPI clock configuration.It seems STM32H7 contains two different source clocks.If I select HCLK3 as the clock source for the QUADSPI Clock Mux, how is the QUADSPI clock frequency calculated? Regardless of selecting HC...
Hi i am configuration UART1 as default and Tx pin switching into GPIO then reset (Low) the GPIO for 28 micro sec(delay) and set(high) the GPIO then again switching to UART1. during switching waveform level is intermediate as show in below. (my...
As, i am using stm32g474ret6 nucleo board, i try to generate a complimentary pwm signal with timer 1 (pin PA0 and PC13) it does generate properly it create a curve at the falling edge .now i change a variable and try to generate this wave of 200khz ...
Hello everyone,I'm facing a weird issue about Flash programming on a STM32g0b1 microcontroller on IAR Workbench for ARM. ContextI'm working on a bootloader project. I am able to lock, unlock, erase and program flash at the beginning of my program. Fo...
Hi community people, As an introduction, please note I'm completely new to the STM32 world, and back in embedded world after a long break in the application level. I now jump in a new project that will be based on a STM32U5, and I start digging in do...
Dear Community,I'm working on STM32H743ZIT6 based project.Here I want to set up 4 ADCs which have SPI interface.On developer's forum is said "If all ADCs will be sampled at the same point in time with the same settings, then the SCLK, CS, and SDI can...
i am using a stm32f401ccu6 board to receive modbus rtu requests from a master device(windows laptop running simplymodbus) and prepare the response buffer and send itso far i can see that the response buffer is being prepared as expected in the live e...
Hello, After debugging for a customer, I have found that all ST H7 related reference manuals are simply copy/pasting old Synopsys IP settings of the USB HS and/or FS core from an ancient databook. The new driver for the H7RS is again a copy of an exi...
