DAP-LINK

Overview

The DAPlink emulator has SWD download & simulation debugging and has a virtual serial port function. It is an open source emulator officially launched by ARM. It is copyright-free, freely produced, driver-free, and supports all Cortex core microcontrollers (not tested)

SWD interface burning firmware: The engineering environment required to install is too complicated, so I didn’t try it.

Serial port burning firmware: You need to pull the chip BT0 high and then reset it to enter the download mode. Then connect the USB to serial port module through the RXTX pin and burn the firmware into it through FlyMcu (you may need to clear the flash when disassembling the MCU)

When the firmware is downloaded successfully, you can see the device name on the WIN10 interface.

You can also see this in keil to prove that the MCU is connected and recognized. Then the DAP LINK is created.

The role of pressure sensors in mobile phones
Smartphones are now indispensable communication tools. There are many types of sensors on smartphones, and each sensor plays a different role. So what is the role of mobile phone pressure sensors? Her
ADC problem of lpc2220
while((ADDR & 0x80000000)==0);adc_dat = ADDR;After initialization, the channel is selected and the adc value can only be obtained once, not a second time.You need to select the channel again to get th
Based on stc51, use the change of 18b20 temperature to change the speed of DC motor
1. Control the speed of the motor according to the temperature change. The motor stops when the minimum temperature is reached. 2. The higher the temperature, the higher the speed. 3. The minimum temp
