Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Hi All ,Am imported a example project in stm32cube and i tried to build am getting error as Description Resource Path Location Typenon constant or forward reference address expression for section .ARM.extab LTDC_Paint line 90, external location: c:\...
Hi,I'm getting info on playing mp3 files with my custom Nucleo-U5A9 (originally a NUcleo-U575, I replaced the MCU and added xtal). I'll be using the audio codec TLV320AIC3110 with I2C and SAI from the U5A9. I'll be using ThreadX, FileX an a uSD card....
Hello ST, I am having some trouble generating two PWM signals for a push pull converter. Ideally I would like the PWM outputs to look like this, I would like the PWM frequency to be 100kHz and a duty cycle range of 0% to 50%. I have connected the p...
This branches off from the second question I asked in here. Using the example code (Ux_Device_Audio2.0_PlayBack) right off the bat does not work, and this is what I've done so far.HardFault DiagnosisEncountered HardFault_Handler() when audio playback...
Hello,In the STM32CubeC0 v1.4.0, when I enable the BYPSHAD bit in the CR register and later try to deinit the device, I get an ERROR. It does not happen if I disable it before deinitialising. Should I disable it by hand, or is it a mistake and should...
Hi everyone, I'm using an STM32H743 MCU with an LTDC display and lvgl for management.I'm using the graphics accelerator correctly to decode an mjpeg video in YCbCr, but I can't convert it to RGB565 with DMA2D.If I try to convert without DMA2D, I get ...
Hopefully this is not a dumb question...I am referencing the example code here:https://github.com/STMicroelectronics/STM32CubeG4/tree/master/Projects/STM32G474E-EVAL/Applications/OpenBootloaderI see the entry point for the the open bootloader app (ap...
Hi,We are building an IoT device, using STM32L476RET6 as main core. It communicates with an LPWAN modem with AT-commands via UART. We have redirected UART2 into external pins for "serial output" into Nucleo RX pins.During testing, we noticed initiall...
Hello everyone, I am using an STM32 microcontroller and I am facing a problem when I try to mount an external flash memory. The problem is inside the function lfs_dir_fetch which is returning unexpected values in the test buffer here: struct lfs_dis...
So I made a custom bootloader that I use to update the MCU firmware. So I have both the bootloader and the main app in the Flash. What I wanted to do, is to write on a specific address (out of bootloader and application, of course) a kind of a flag t...
