I have an STM32L452 rigged to use an external clock so we can keep the RTC running. Schematic attached.X2 is a clock from SiTime, programmed to be 32.768kHz. C36 is a supercap acting as battery backup. I used STMCube to generate the startup code to f...
Hi, I'm new to this, so bare with me :) I'm following the UM2421 - getting startet guide for the P-NUCLEO-IOM01M1, and everytime I connect the USB to my PC, I get the FAIL.txt where it says: The interface firmware FAILED to reset/halt the target MCU....
Hi, Currently we have received our first prototype batch of board with the STM32H7S7Z8J6. There is external flash and ram on the board also, but first we want to try a simple test where we will just use the LTDC interface without touchgfx to make the...
Hi, when configuring the Lora stack it requires RTC in free running mode along with some alarms. I am looking for ways in which I can get epoch time in my application layer. Thank you for any comments on thisRegards
It only gives the bit and the description: Bit 22 HDRXGNEQEN: Enable HS Rx gain equalizer 0: Disable the gain equalizer 1: Enable the gain equalizer But what does it actually do? When would you want to use it? Thanks
Hi,I am using STM32H563ZI to design a new product, there is a SDRAM(W9825G6KH-6) connected to the MCU with 16bit width bus. The SDCLK is 125MHz while the MCU running at 250MHz. The read and write to SDRAM address space are both OK. But the read writ...
Hello Folks,I am facing the issue regarding the RTC in stm32H7S78-dk evaluation board. So, the issue is if I configure the internal RTC in my IOC file all the other the process stops on my board which is working already like TouchGFX, Ethernet my LCD...
Hi,What are the different power saving mode for STM32H753 with there current consumption. What are the active functions in each mode?
Subject: Hello,We are working on implementing a dual-role USB Power Delivery (USBPD) setup with an internal battery. The system is designed so that when an external charger is connected to the STM32U575ZI, it charges the internal battery. However, wh...
Hello,We are using STMU575 MCU and it's power saving mode STOP3.For verification purpose we are using NUCLEO-U575ZI-Q eval board, ST cube example PWR_LPMODE_RTC (STM32CubeU5-1.7.0). ST cube IDE version is: 1.18.0.I modified existing code little bit (...
