STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Hi,Some doubts on the ECC functionality on STm32h74x.How can we know if the data can be corrected for cases DEDF and DEBWDF ? I always see the DEDF and SEDF fields set in my case. This bits are set when the control is hit the main(), and then I clear...
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...
HiIn the reference manual, RM0481 rev1, for analog watchdog window it mentions SQRi and JSQRi registers. I can not find any descriptions about these registers.Can someone help me clarifying this?BrImre
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...
