Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
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,I had a question regarding Bruno's excellent series on creating a simple bootloader.In part 3, there is an if statement which checks if something has in fact been loaded into the applications's flash region:// bootloader main.c if( ( *(uint32_t *)...
Hi everyone,I am working on an USB-PD source that is battery powered.To make use of the low power features, I defined _LOW_POWER.When this is defined, I get a problem in connection with eletronically marked cables (EMC). Non-EMC cables work fine.The ...
HiI'm trying to read the output from BARCODE reader (ES4650) using USB-HOST using CDC type.On connecting the USB cable I'm getting SOF interrupts (although I disable the Signal SOF on CUBE). On pointing the barcode reader to a barcode I'm getting som...
Hello together,after a lot of trouble getting the USB HS port working on the STM32H747 on the STM32H747I-DISCO Discovery kit I’m stuck again. I’m using STM Cube IDE 1.7 and the HAL USB CDC lib.I was able to get USB CDC working on the M4 thanks to htt...
The X-NUCLEO-LPM01A PowerShield has a dynamic current range maximum of only 50mA.This is a long way short of the maximum current found in many STM32 applications; eg.STM32WL - max Tx current is 120mA;B-L072Z-LRWAN1 - max Tx current of the radio modul...
after extract the zip file to the shortage path C:\st2\STSW_STUSB010_v1.3\Projects\STM32F072RB-Nucleo\Appli\usbpd\STM32F072_MB1303_DRP_2PORTSthen import the example with STM32CubeIDE. Then compile result was"Build Failed. 34 errors, 3 warnings. (took...
Hello everyone,I write HAL_Delay(1000) or HAL_Delay(5000) on my code but it delays it by half. I checked SystickTimer it works fine. But HAL_Delay function gives me half delay time. I created another project with same board, same Cubemx features , it...
I've been struggling to get FatFs working on STM32L496 / L471 for some time now. At present my code uses polling which even at low card clock with certain interrupts disabled is not reliable enough, giving me random FR_DISK_ERR. I know I have to get ...
I'd like to develop USB host application with Audio and/or Video class.Is there any working example project or code snippet?I checked STM32 HCD driver file - -ux_hcd_stam32_periodic_schedule.c, but it always generates EP_TYPE_INTR packet. How can I s...
