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...
STM32L0C8T6 failed to communicate with M24C02 through IIC，iic uses cubemx default configuration，The relevant code show as below：#define ADDR_24LCxx_Write 0xA0#define ADDR_24LCxx_Read 0xA1#define IIC_BufferSize 256uint8_t IIC_WriteBuffer[IIC_BufferSi...
How can I change the driver to port 4 or how can I install the driver additionally for port 4? *Edited by moderation: please don't mention your email address publicly on this forum*
I want to load the source of the STM32F1xxx product for benchmarking.Please tell me the required environment.I want you to teach me both software and hardware.
I use STM32F103C8T6 as SPI slave and want to send data on request by master.The master sends to the slave a byte, which has to be used to decide, what has to be doneor what data data has to be sent to the master, and a fill byte which is neededto shi...
