[i=s]This post was last edited by mars4zhu on 2014-11-27 11:32[/i] HRM_LowPowerRTC is a low-power RTC. It usually enters low-power mode. After the RTC wakes up, it notifies the phone to update the hea...
Can the STM32 serial port interrupt be set like this, that is, to set the number of characters received to trigger the receive interrupt. For example, if 8 bytes are set to trigger the interrupt, an i...
1. Output Impedance
Before understanding the issue of "impedance matching", let us first learn what "output impedance" is?
In actual circuit design, whether it is a signal source, amplifier or power s...
Start using stm32 to drive the camera OV6620 The current idea is to control the camera to collect photo data through stm32, and then transfer it through DMA after capturing the corresponding edge, bur...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
