Hey experts, has the low-power mode changed now? It doesn’t actively enter anymore. In previous versions, it would automatically enter low-power mode after a power cut for a while, right?
No changes were made. Additionally, the previous logic description was incorrect—it’s not that the device enters low power mode only when power is cut off, but rather when the CPU becomes idle. Please check whether there are still threads or tasks running that are keeping the CPU in an active state.

Alright, thanks for the clarification,大佬. I have another question: my project is based on the example project of LVGL v9. When I used that example, I enabled the FPS, but it’s not showing up on the screen. Then, I found the LVGL v9 path through the compilation path: SiFli-SDK\v2.4.4\external\lvgl_v9. Is this path correct? I did modify part of the compilation, and indeed saw some changes. However, even after changing the LV_USE_SYSMON flag as suggested below, it still doesn’t work. Could it be that something is still not enabled in menuconfig? I’ve searched everywhere but couldn’t find it ![]()
In menuconfig, disable LV_USE_PERF_MONITOR_LOG_MODE. Originally, performance data is printed via log by default; after disabling, performance will be displayed via label instead.
The performance monitoring related logic is located in lv_sysmon.c.
Alright, thanks for the reply from the senior. The issue has been resolved—just needed to disable the following log in SDK version 2.4.4. Besides this, I have another question: how can I configure the SDK so that I get function auto-completion while writing code? It’s really inconvenient when developing with this SDK and LVGL, having to check each function on the official documentation one by one. Could you please give me some hints on how to set this up, so I can go ahead and fix it?
What do you mean? Aren’t features like function hints and code completion built into IDE software like VSCode? Or are you referring to our official plugin? 准备工作 | SiFli-SDK-CodeKit
Yes, when using the official plugin and copying the official examples as templates for your project, you don’t get code suggestions like you would with ESP-IDF. I’m wondering if modifying the JSON file is the right approach.
