debugging with external loader
I'm working with an external loader. I choose it from debug config and save my images to the qspi flash. However, everytime I debug my code, do I have to save images to the qspi flash again and again?

Resolved! Why is there so much latency in my interrupt?
I am working with the STM32 Nucleo-64 development board, which has an STM32L476R microcontroller. My SystemCoreClock is 16 MHz and TIM17 is clocked at 4 MHz. To my surprise, the code below only works well (the timer doesn't miss the next interrupt an...
What is the expected current taken by an unprogrammed STM32F4?
I have my own board and it wants to take >20mA at 3V3. I don't want to increase the current limit if there's a short, but I don't know what it needs. What sort of current should I expect before I program it? Thanks
Resolved! SPI Transmit in DMA circular mode not call Tx_complete_callback?
i want to interface shift register(74HC595) with STM32F103C8T6 MCU using SPI Transmit only master mode.I need to continuously write shift register so it is continuously update op pins. so i set SPI DMA in circular mode and when transmit complete i ne...
Resolved! STM32L031F6P7. Unique Device base address: 0x1FF8 0050 is always same. Serial trailer always 0000.
we bought at Arrow, Date code 2142, COO:PH, CC:RHC. Debugger always shows:
Resolved! how to store signed hexadecimal data from a sensor and identify if the hex is negative or positive?
I have a sensor that can communicate via UART, I send a command and the sensor answers me with a hexadecimal frame.I can have distance, angle, velocity values. I know how to store the frame in a buffer but I don't know how to store it in hexa to kee...
How to find where RXNEIE is reset to 0
Hello,I'm debuging some legacy code for an STM32L476RG MCU. USART2 is enabled, and used as an UART, with DMA for TX, and one interrupt per received character. I'm using STM32CubeIDE 1.8.0.Each time a character is received, the HAL_UART_RxCpltCallback...
wake up logic on stm32l4
I want to wake up from standby for each transition on a wkup pin. For example, on waking, read the wakup pin and set/reset the bit in pwr_cr4. (pin high -> bit high, pin low -> bit low). Is there a race condition ? The reference manual is vague on...
I2C Master Sequential function
Dear,I currently use a STM32G070 with external touch sensor component usuing I2C interface.This component aloow me to communicate with it only during a ready window and this window is automatically closed after a delay without communication or a I2C ...
Resolved! STM32U5 documentation error in HSI -> TIM5 interconnect section
In section 16.3.7 of STM32U5 RM0456 Rev 2, the following text appears in the bullet that notes MSIK, HSI and LSI are linked to TIM2/TIM3/TIM4/TIM5:"External clock mode1: Table 446: Interconnect to the tim_ti1 input multiplexer for TIM5, tim_ti1_in1 (...
