I am developing software on the Nucleo-L433RC-P board but have a strange situation when debugging.The first time I debug, the software does not run and I get the following error... Break at address "0x1fff2ce8" with no debug information available, or...
I have an STM32F401 nucleo board and it used to work fine but now after a minute of connecting it with usb, the LD1 suddenly dims to very low light like pin on float. Before that it works fine, I can program it, debug it.
I am using one of the 32 bit timers to measure intervals for fault protection on a HV pulse modulator. I have an interrupt on EXTI that captures both leading and trailing edges of the command pulse. In the service routine, I simply store the lates...
My simple program to test wake from standby with PC13/Wakeup_pin4 is working. I use the pushbutton on this pin as an EXTI and had to add the GPIO_DeInit before setting the pin as an input without EXTI.The same code does not work in my larger program...
Split from:https://community.st.com/t5/stm32-mcus-products/is-is-possible-to-wakeup-the-stm32l496-with-an-external/td-p/741267as this is a new question.Hello @STTwo-32 as the wake up pin associated with stm32L496 is SYSWKUP2 can i use this and on cli...
I'm using UART7 on a STM32H743 to drive a RS-485 transceiver. I've set it up to use the hardware DE pin to switch the transceiver between TX and RX modes. I transmit 14byte messages to devices on the bus, and they send back ~14byte messages. My code ...
I’m working on a design where I need to communicate with two SPI devices that operate at different logic levels:1) A sensor running at 1.8v logic (need SPI + 2 other lines, all at 1.8v) 2) Everything else on my board, preferably running at 3.3v, I wi...
Moved from this thread. HiI'm experiencing the same issue that others have reported with the STM32H755ZIT6. Despite following all the suggested solutions step by step from various forum threads, I’m still unable to debug or run code on my Nucleo boar...
I'm trying to understand the operation of the STM32F446xx family of microcontrollers. I'm reading the reference manual that's available here: https://www.st.com/resource/en/reference_manual/rm0390-stm32f446xx-advanced-armbased-32bit-mcus-stmicroelect...
I have measured the MCU current on the NUCLEO-L433RC-P dev board by removing JP6 and connecting a multimeter. The current in shutdown is ~1mA, why is this so high ? The shutdown current should be nA or uA at most... To shutdown I call "HAL_PWREx_E...
