Hello,I am using a STM32G491 in LQFP48 package. In the RM0440 rev8 page 2122 the package code for LQFP48 is 01011. But I read 01001 which would be LQFP32. The device id 0x479 is correct. Is there a reason for this? Thanks.
Hello,I have a custom H743 board with Microchip USB3340 external PHY (REFCLK = 24MHz, dedicated external oscillator)In an code that use ChibiOS, my configuration should achieve HS mode, but ultimately, after handshake, it revert to FS mode (12Mbits/s...
I'm working with a legacy project that uses some EEPROM emulation code on a STM32F103 MCU. I need to find the original release file containing eeprom.c and eeprom.h of that emulation code. The description of the header file looks like this: /*******...
I am currently using a FreeRTOS example project with the stmwL55, but instead of the defaulted heap 4, I am selected heap 5 in the ioc to utilize RAM2 for the 28kb. I have used the suggested example of how to initialize the heap before task creation....
I'm creating some SPI slave code using an STM32 on a G474RE board. The protocol is that the master sends two command bytes, and then the slave sends back a single byte response. My SPI is a little rusty, but as I recall the way you do this is to ha...
Because there appear to be little/no stock of the STM32U535CEU (QFN Version) I'm left with a dilemma of whether to use the built in SMPS. Some documentation in another post describes how to connect up when not using it but how do you switch between ...
Hi eveyone,I have a problem with RTC wake up. I use LSE 32.768kHz.I run example from manufacturer to wake up MCU from Stand by mode very 1min, 2mins. Everything work okay.But, When I put delay 10s and HAL_PWR_EnterSTANDBYMode(); into while(1). Everyt...
Hi expert, our project is currently in the development stage. We are using the NUCLEO-H753ZI Development Kit for firmware development while awaiting the arrival of our custom board from the manufacturer. The dev-kit employs the STM32H753ZI (LQFP144),...
HiWe are trying to use the f746 disco kit as a udp server that writes what it receives to an SD card. The kit is currently connected directly to a PC with ethernet and usb. As this is our first stm project, we tried following several tutorials that a...
