Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
My previous question was how to detect a cable and they said to use a EXTI to receive a VBUS detection. The customer wants to use USB to program a blank device (so nothing configured) and EXTI is a block of interrupts and could be multiple pins. Ple...
I downloaded Azure-IOT example for STM32U5 which works on IAR. I am trying to add a c file to secure application. I am able to compile and even see that function is hit while I debug.After this function call, the board is getting rebooted with below ...
I'm wondering if i'm missing something here.I've hooked up BOOT0 to the 5V pin on CN2. I have nBOOT1 set to 1, and i'm connected to the device via the ST-LINK as the other usb port doesn't seem to be active. I've also installed the udev rules, and ju...
HI all,I need a sampling rate of 1K to collect the analog voltage.My chip is :STM32F103C8T6.I use Timer2's interrupt to enable collect and send data, after send disable.I use a plus at 100Hz to verify, find it will lost some data:ThanksBoone
Dear Forum, I am using STM32H735 with RTOS LwIP with a DP83826 PHY, and want to see at least a ping on the network. From HW point of view the PHY seems to work because I can communicate with it and read config registers. The strap pins are set to a v...
Hi,I'm working on my STM32 project, having DFU mode on machine. (using UART bootloader)I just have failed to DFU my STM32L451RCT6, but with same logic, -RET6 has succeeded!When I send EER(Extended Erase) command (0x44, 0xBB) to RCT6, It send me ACK a...
The program jumps to the address but stuck in HAL_Delay() without HAL_Delay() its work perfectHere is the code...........static void goto_application(void){ printf("Gonna Jump to Application\r\n"); void (*app_reset_handler)(void) = (void*)(*((volatil...
Hi.I used USB_OTG_FS as Audio Device Class on STM32F407-discovery.I connected PC and STM32F407-discovery with USB device.When I played music, sometimes sound is not occurred on STM32F407-discovery.I found that epnum in USBD_LL_DataOutStage is always ...
The composite device implementation (CompositeBuilder) provides more reliable method to define USB descriptors and methods but I think it lacks some documentation on how we use it. Moreover, there must be some additional changes required for individu...
