Hi there!I 've got a project where i use the STM32H757 dual core (Riverdi 7")the M7 core runs freeRTOS with Ethenet (ping and echo OK)the M4 coreruns freeRTOS with ADC using DMA and some EXTI (working as expected)When starting the M7 core first and ...
In the official example（Ux_Device_HID_CDC_ACM），HID devices as mouse/* Mouse event. Length is fixed to . */ hid_event->ux_device_class_hid_event_length = 3; /* Set X position. */ hid_event->ux_device_class_hid_event_buffer[0] = x; /* Set Y...
Hi,I am trying to generate waveforms using the STM32H563 microcontroller and several AD5791 DAC ICs. I am using the ADG732 Multiplexer with 5 select lines to connect my CS line to the required DAC IC. A simplified image of the hardware is provided be...
Hi, I am using Olimex STM32-E407 evaluation board which has STM32F407ZG. I tried Freertos,LWip etc successfully. But when i tested SD card interfaced with SDIO, i got errors. Failed to mount SD Card. I am attaching the main.c file herewith. Kindly he...
I'm working on a project using an STM32H7 series MCU with FreeRTOS. I've customized the .ld file to configure the stack and have set up the internal ADC and DMA to continuously read and store ADC values. I've statically assigned the DMA data register...
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 ...
