STM32F401 low temperature problem
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 ...
Programming Erorr
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...
Resolved! gpio let down 5 V pull-up
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...
How to make NUCLEO-H745ZI-Q do anything?
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...
Newbie question about PWM output accuracy
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...
GAM module of X-CUBE-AUDIO does not work with STM32L
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...
Setting Brown-Out Threshold in Option bits
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...
