Port Multiplexing is the focus, as long as the use of stm32 is used to peripherals, peripherals are shared with the Gpio pin (multiplexing), that is, some pins can be purely as input and output, but also as a certain function of peripheral (such as ADC, serial port and so on) pin port.This is an advantage of stm32, which saves the number of pins.Port multiplexing and remap pin correspondence can be queried

Windows is the host machine, and Linux is installed in the vmwarevm. You can also write a program in Linux to send messages to the serial port. The same principle is to use the virtual serial port software vspm to connect com3 to com4 and then capture it through the serial port debugger. The following is a C sample code for the serial program in Linux. The use a

Sometimes we worked hard to install a service but found that unable to access, thinking that they did not install success, in fact, the solution is very simple, is to open the relevant port. For example, if I install Nginx or Apache, I need to release port 80 on the firewall. The relevant instance code is as follows./sbin/iptables-i input-p TCP--dport 80-j ACCEPT #开启80端口/sbin/iptables-i input-p TCP--dport 2

Give the users of cool dog software A detailed explanation to share the tutorial on breaking the port blockade. Tutorial Sharing: At present, there are many routers and operators to peer-to-peer download software (such as thunder, cool dog, etc.) the default port is blocked, if need to break the blockade will need to modify the software default port.

How to disable port 445 and port 445 Some ports in the system are usually unavailable but dangerous, such as ports 139, 135, and 445. windows is open by default. In this case, you can manually close these ports! Next we will introduce a windows Group Policy to disable all the dangerous ports to be disabled at one time.Method/step 1Select "run" from the "Start" menu, enter "gpedit. msc", and press enter to

Currently, the serial port 0 of Wince is used for debugging the serial port. However, because my case requires three serial ports, I need to change it to a common serial port, but I still need to print the debug information when I start the system, in view of this, I modified the following: Debug. add a line in C: int debugconsoleenabled = 1; make a judgment when
