How to disable the system's automatic pop-up low battery warning in Wince! Because we made a shell ourselves, we need to disable all the system's automatic pop-up messages, otherwise the interface wil...
I would like to ask the engineers who make MP4, when you do power management, do you use the charging circuit, DC/DC, and LDO in one circuit, or separately, or does the main chip include the charging ...
Sorry for the jokes~~~ [u] Question 1: What wireless technology do wireless routers generally use? Question 2: What CPU and OS do wireless routers from manufacturers like CISCO, Huawei, TPLINK, D-LINK...
When doing a project, I used STM32 and voice chip WM8974. The I2S interface of STM32 is standard 1. LRCLK 2. BCLK 3. SD, but the interface of WM8974 is 1. LRCLK 2. BCLK 3. VIN 4. VOUT. How to connect ...
The FPGA is used to collect frequency pulses, but the rising edge of the incoming pulse square wave rises too slowly. Since the FPGA clock is fast, the intermediate value will be collected. How can I ...
