hello, I am currently doing my thesis project, part of my job is to achieve low power consumption in a bluepill, I have doubts in low consumption modes, according to the data sheet in stop mode the stm32 reaches currents of order of the micro Ampere in the stop mode, however I never get those consumptions for the stop mode, in fact the current consumption gives me practically the same as what you show in this video. my teacher insists that the consumption of the bluepill must be equal to that of the stm32, my question is, do you know what the consumption is due to? in stop/8MHz mode I get 2mA and in run mode I get 9.8mA.

Nice video! How about clocking on LSI instead of HSI?

Hai great tutorial there !, i want to ask question, if it is possible to wake up from standby mode using wakeup pin PA0 pin as button?

@user-fj9lp7ot7v 8 ай бұрын

Hi, I read from datasheet that the current consumption goes down to tens of microamps in standby mode. It is 0.32mA in the video? How can we further reduce it?

Very interesting. Some time ago I was looking for examples on how to reduce the STM32F103 power consumption, and found very little. Will you publish your code?

Did you try with a screen i2c type SSD1302? I ask you the question, because with microcontrollers type atmega328, there are conflicts between the i2c and deep sleep modes.

I tried it with OLED too (SSD1306). But OLED i not lowpower friendly so I prefer LCDs in such applications. I didn't notice any issues with I2C, maybe because I use SoftwareI2C which is much faster and uses much less memory that Arduino Wire.

Looking a little not to put the pin analog standby, I can not do it, what do you think?

It s all right now: "sleepMode(false,delTime/1000); setPLL(RCC_PLLMUL_9); adc_enable(ADC1);" adc_enable(ADC1) at the end of function sleepMode() Thanks for your work ;)

How did you get as low as 1mA? On stop mode@24MHz I measured 3.9mA on my board! Do removing debugger pins (SWIO, SWCLK) make a difference? I see you just power it up with 3.3 and GND...

@cbm80amiga 3 жыл бұрын

I only removed power LED. Make sure you have genuine STM32 bluepill, those fake chips can work different way.

Hello, thats a great demo showing the low power modes. Do you have any examples for using the STM32 generic core HAL Timer / interrupt timer.h ?

What libraries do I need to install in order to get this code working? Please tell, I have a delayed project just waiting because I have to implement sleep mode.

Mainly Roger's stm32duino. For N5110 I used my own N5110_SPI available at my github
