I've been having issues with my bluepill chip ( stm32f103c8t6) concering its significant current draw . I know that bluepills aren't the best choice for low power projects but they should at least draw less than 670µA in stand by mode ( according to ...
Using an STM32U575 on our own design. Aim is to put it into Stop2 Mode and wake up from three sources:a) GPIO pinb) Wake up timer (RTC)c) AlarmA (RTC)I have these three sources setup as interrupts and when the CPU is running (i.e. not stopped) these ...
Hello,I've designed a board with the MCU above. The board has the following peripherals/configurations:-i2c-spi-gpioA-gpioB-EXTI and timer interrupts-serial wire debug-timers (tim2, tim21, tim22)The board has some ICs that are all in their lowest pow...
I am starting with the STM32L011 MCU (NUCLEO-L011K4 kit) and I want to use it for a very low-power application.I need an operating frequency of 65536Hz to generate a pattern on a GPI/O continuously.So I configured the STM32 in LowPower Run mode with ...
I am using STM32L031 for my project and since it is battery operated, I am planning to use Low Power Sleep mode for the same. And for that, I need clock below MSI range 1. So I chose to switch to 65kHz clock. But it gets stuck somewhere during clock ...
Hi. I am working on a battery operated project using STM32L031 microcontroller. I am using 32 MHz clock for normal operation. But if I use same clock in low power mode then it consumes current of about 2.7mA. But for higher battery life, current cons...
Hi. I am using STM23L031 for a battery operated product. The expected life cycle is almost 1 year so I need to save battery as much as possible. So I wanted to use Low power sleep mode when not doing anything(I chose this because I need DMA for UART ...
In short, SLAK bit won't reset when SLEEP bit is manually reset. In details :I am trying to achieve a successful transmission in loopback mode before venturing into making a network. I had it working at a point after a lot of documentation reading, b...
How to generate a break when the supply voltage drops below a certain value in the HAL?Andrzej
If you put a breakpoint somewhere within the program and then put your device in standby mode via:HAL_PWR_EnterSTANDBYMode();While the debugger is still connected to the device (and the device is in standby mode), if you terminate the debugging sessi...
