i have two questions how can i lower the CPU frequancy so the power consumption will be lower - where can i configure this?and the second is how can i place the CPU in sleep mode and still show a screen saver on my display - thus reducing the power c...
Like a few others on the STM32H7 line I as seeing some weird behavior with ACTVODSRDY.This happens with both the demo projects and my own code.Sometimes when I power up this board ACTVODSRDY = 1and PWR control register 3 (PWR_CR3) is in the expected ...
I'm trying to implement a screen saver/sleep mode onto an application so if the screen hasn't been touched for a period of time the device will enter a sleep mode (turn screen off, save power, retain state of the model). Then only when the screen is ...
Hi, I followed the touchGFX workshop today and at a certain point we had a discussion about the problem of using state preserving low power modes of the cpu in combination with running touchGFX.The example that triggered the discussion during the co...
I'm using TouchGfx 4.6.1 (I know, pretty old Draupner code from 3 years ago). The application runs on a STM32F469 with an AMOLED MIPI-DSI display.I am trying to render a screen, put the processor into STANDBY, the display into its lowest power idle m...
Hello,I am making an application using Stm32f429 disco board and my question is:Do you have any solutions for low power consumption,for example, could I change brightness or turn off backlight in the running application?Thank you,Anton
Posted on November 30, 2017 at 16:45Hi All ,I am using stm32f4 Discovery board and after I wakeup from standby mode ,everything works as expected except the LCD ,it only shows a white background and doesn't change .I will start checking SDRAM first,...
