ZigBee Tour (v): Several important CC2430 basic experiments--serial communication first, the connecting link In the wireless sensor network, the CC2430 needs to send the collected data to the host computer (ie pc), while the host computer needs to transmit the control information to the CC2430. All this is inseparable from the transmission of information between the two. In this section, we will learn how to realize the serial communication between PC and CC2430. CC2430 includes 2 serial commu

connection. This process is called the function of redirecting the C language library, as shown in figure 6.For example, a user has an I/O device (such as UART ). The original library function fputc () Outputs characters to the debugger control window, but the user changes the output device to the UART port, so that all () the printf () Series Function outputs of the function are redirected to the

? File descriptor: for example, when a text file is opened, a descriptor is generated. When a UART is opened, a descriptor is generated. When a Socket socket is opened, it is also a descriptor... these descriptors are these elements .. it is about 1024. Check whether it is true. So what are these elements, or what are the operational features of these file descriptors? Well, Linux only seems to have three rwx or 421. in this case, the features of thes

on; for output data, it replaces lf characters with Cr/LF sequences. The n_tty line procedure is used when the UART port is used as a common serial port. When the UART port device uses an Internet dialing connection for the serial modem, the PPP line procedure is used to process data. The PPP ldisc assembles the serial port data from the UART core into the PPP i

Connecting In a wireless sensor network, cc2430 sends the collected data to the upper computer (PC) for processing, and the upper computer needs to send control information to cc2430. All of this is inseparable from the transfer of information between the two. In this section, we will learn how to implement serial communication between P

How to check and use serial ports under Linux How do I check and configure serial ports under Linux for various purposes such as modem, null ing nullModems or connect a dumb terminal?Linux offers various tools. Linux uses ttysx for a serial port device name. For example, COM1 (DOS/Windows Name) is ttys0, com2 is ttys1 and so on.Task: Display detected system's serial support Simple run dmesg command$ dmesg | grep ttyOutput: [ 37.531286] serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A[ 3

Freescale ATK (advanced toolkit) is an embedded system flash burning software designed for its MX series CPU core. It can be used to burn Bootloader and kernel to flash. (Nor, Nand, MC/SD ...). The principle and workflow are as follows: First, set the jumper to UART/USB boot. Then, after the Board is powered on, the ROM in the SOC starts to initialize the internal RAM and waits for data on the UART/USB
