After completion of below checks, control is expected to enter into usbAppcallback function with via HAL_HCD_IRQHandler(). Interrupt is occuring but it is failing to enter usbAPPcallback function which changes the device state.
We are trying to make our first large project with an STM32G473VE MCU in an LQFP-100 package, but there seems to be a discrepancy between the number of accessible ADC input pins for ADC5 between the datasheet (rev 3, last version) and what I can sele...
The STM32F777 has a bullet under Section 2.25 [U(S)ART] :Swappable Tx/Rx pin configurationWhere can I find more detailed information on Swapping the Tx/Rx pin configuration for a UART ?
Hi, I am using STM32F401CCU6 on my circuit and it working well at room temperature. When I was testing the circuit in low-temperature below -10 degrees the RX of UART1 lost messages, when I came back to 0 degrees the circuit is coming back to normal ...
Dears I'm using board "STEVAL SPIN3202" to drive a BLDC Motor. To program the microcontroller , I'm using STM32 Motor Control Workbench software. The mode of driving is sure FOC since I'm using this software. The problem, However, happens when I acti...
I use stm32f401's PB4 (NJTRST) pin. I attached 5 V pull-up resistor (5.1k) to PB4. While MCU is in reset mode the voltage on PB4 is 4.26 V. Only after starting the system, the voltage increases to 5 V. In my program I configure PB4 as input without p...
I've been trying to make LED blink. GPIO PE1. So i wrote this code:HAL_GPIO_TogglePin(GPIOE, GPIO_PIN_1);HAL_Delay(200);When i'm creating procject for this board it creates two procject for each core CM7 and CM4 each with it's main.c. I can debug eac...
Hi, I'm testing various PWM scenarios and found that output frequency does not match with expected. I'm using formula Period = (PSC+1)*(ARR+1) / TmerClockFreq in seconds Period = 1000 * (PSC+1)*(ARR+1) / TmerClockFreq in milliseconds. The board is Nu...
I tried to use GAM module of X-CUBE-AUDIO. In the documentation, it says that it can be used with any STM32 which possess M4 core however when I try to use it with STM32L series one, the function of the module returns -6 which indicates wrong hardwar...
Hi,for my application, I need to set my BOR threshold to about 2.5 V in my STM32L476RG. My understanding is that the preconfigured threshold is at level 4, which is 2.8 V (see RM0351 Rev 7, page 111).What is a good strategy for setting the BOR_LEV bi...
