I would like to know the necessary operations and settings from power on to GPIO control.I have made a board using STM32H743XGH6.I want to set the GPIOs to turn on the LEDs, but it does not work.I am setting the GPIOs by manipulating the registers di...
I am studying the architecture of the STM32H7 family, and according to the AN there are various types of memory, DRAM, SDRAM, NOR/PSRAM, NAND in addition to the swap between SDRAM and NOR/PSRAM.What is the reason for such diversity and what benefits...
Greeting Everyone,I am facing an issue with my STM32 board having STM32F103C8T6 as MCU, while trying to see a normal "Hello World" output. After debugging the board, I attempted to connect it to my PC via the serial port. To ensure proper communicati...
I was wondering by which reason the HAL_LPTIM_AutoReloadMatchCallback is not being called. All the functions called in the inside the HAL_LPTIM_Init return HAL_OK.
Hi,I've been searching for STM32U5G9ZJT6Q BSDL file, but I couldn't find it. Could anyone please share it with me?Thank you,Best regards
Hi All, I am trying to reduce the boot up power consumption using STM32U575RIT6xQ . I using a 4-20mA power source and the boot up power is 7.6mA. After it boots up the power consumption is 3.4mA. We are using Free RTOS. Below is the pins that are act...
I have on my desk an STM32F407 Discovery board and an STM32U083 Nucleo board. My intent is to write software for the F407 to bootload the U083 via I2C. As far as I can tell, these are the general steps:Drive BOOT0 high and pulse the NRST pin on the...
Hi, I try the whole day with an F103C8 to have the Alarm Pulse on Tamper Pin C13 but it is not possible, I tried with PullUp resistor and also I tried to configure manually the GPIO Pin to AF OD config. But with my Osciloscope I cannot see anything. ...
On page 1017, Section 31.3 in Package data register of the STM32C0 reference manual (Revision 5), looking at the PKG[3:0] bitfield, when the condition is STM32C071xx, there seems to be two parameters with the same value? Was the value 0b1100 intended...
We are using the part STM32U585 controller in our board and we have designed it with battery backup support of 3.0v We are evaluating the backup ram (address 0x50036400)performance and found that it is not able to retain the information on power down...
