I have several devices connected through a CAN network. Using an STM32MP1 I want to build a web frontend that can be used to not only issue commands but also receive arbitrary data and present it to the user. (Data from the devices).I'm trying to f...
The STM32 MCU and MPU portfolio brings developers a wide range of design possibilities to make industrial applications smarter, more secure, and more connected.In 2023, we will continue to deliver on that promise.Join us for the STM32 Innovation Live...
I am trying to read data using ADC1 continuously and copy it into a buffer via DMA.However, the data is only read and copied once (seemingly correctly), and afterwards nothing happens anymore (data in buffer does not change, ADC1_IRQHandler() is not ...
Hi in one of link https://wiki.st.com/stm32mpu/wiki/I2S_Linux_driver#Short_Descriptioncan i2s1 used for mclk generation, and will the parent clock able to generate mclk for different audio different bitrate,because in dk2 we use i2s2 for mclk generat...
We try to configure the (M)DMA in Linux device-tree for our System on Module board based on STM32MP151/7C but it always said us that it cannot configure it so we had to disable dma for memory (QSPI Nor/NAND and FMC Nand) which cause performance issue...
I want to connect a 128x64 LCD to my STM32MP157D-DK1 board and implement a program on the A7 core Linux to display some parameters. What should I do? Thanks in advance.
Do we need to compile CUBEMX dts files before bitbake or we need to convert them into the dtb files with eclipse like in this ST video and what is the best way to go from discovery board to custom board in the means of creating device tree files for...
I have a large firmware that the MCU must execute. It will not fit into SRAM1-4, so I am trying to move the entire code (or a portion of it) to DDR RAM. I have no problems reading and writing DDR memory from the MCU, as long as it's just data, but fo...
hi, i'm trying to make USB_FS work on my custom board. my desired configuration is peripheral (otg can be ok, i have jumper on id: PA_10)i already have 2 USB HS so i can use only USB_FS mapped on PA_11 and PA_12 as OTG. i follow the st wiki at the po...
