Hello again,Here's what I want to do:1) wait for the UART_FLAG_RXNE to be set2) receive one character3) switch based on that character (character is saved for further processing)4) receive the proper number of following characters based on the comman...
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 ...
