I have an app where I timestamp all the data I get from a bunch of external devices. I'm trying to come up with the fastest way to read the RTC and have 2 approaches, one using snprintf and some LL driver code that's pretty easy to read. It's not m...
We are developing a device that periodically boots in Sleep mode using the STM32G04.Set the WakeUpTime with HAL_RTCEx_SetWakeUpTimer_IT and enter Sleep with HAL_PWR_EnterSTOPMode(PWR_LOWPOWERREGULATOR_ON, PWR_STOPENTRY_WFI);.If you make a program to ...
We have a very weird behavior in a battery powered IoT device. We should have a very low STOP mode current draw of 1.4 uA @ 3 VCC. The problem is, as soon as we use the RTC Alarm just once and although the alarm already fired during NORMAL operation,...
Greetings,I am writing here because I am out of solution for making the F401CC RTC use the reference clock detection feature to correct its timing. Everything in the RTC is working fine in my application, except for that feature. I use a STM32F401CCU...
I am using STM32F103ZGT6 I have initialize code From STMCubeMx with settings-> PLL -ON , HSE -ON , LSE- ON for Internal RTCI have written code to retain date for internal RTC. I want the event when RTC switches from VDD to VBAT , as per my applicat...
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
Hello, I am using STM32F446RE in my project and as per the project requirements I need to have power on built in test, initiated built in test and continuous built in test on STM32F446RE. Please let me know how different built-in self-tests can be ...
I am using the RTC of the STM32L4 Discovery board and have noticed that the sub-seconds are counting down. Is there anyone with an idea on how to resolve this issue?
I had use VBat with external low frequency OSC for RTC which it's can run fine even reset has occurred. But it's has problem when it was boot from power off with VBat. it's going to TimeOut error while checking LSE state in RCC initial./* Check the L...
System: STM is set to use a PLL fed by MSI. The PLLM is set to 6 and the MSI to 48 MHz.Issue: When HAL_PWREx_EnterSHUTDOWNMode is executed, the processor should stop executing instructions after this command. Yet occasionally it goes past it indicati...
