Application of 51 MCU serial port mode 0-EEWORLD

Collect

I will not introduce the application of the microcontroller serial port in detail here. Here I will only describe how to use serial port mode 0. When you look at the application of the microcontroller serial port, you will know how to set the working mode of the serial port. In fact, if you really only use serial port mode 0, you don’t need to set any registers. You only need to send the data you want to send to SBUF.

like:

/***********************************
Function name: HC_595_input()
Function description: Send data from HC595 to storage register
Parameter description: dat -> data input to 595
Return value: None
***********************************/
void HC_595_input(unsigned char dat)
{
SBUF = dat; // Send data, low byte first

         while(!TI) // Waiting for sending to complete
         {
                    ;
        }

TI = 0; // Allow next sending
}

51 single chip microcomputer reads out the two-digit BCD dial program

Question: I made a small design using AT89C2051, where P1 is connected to a two-digit BCD dip switch, P3.2 is connected to a switch, and P3.3 is connected to a relay. The specific connection method of the two-digit BCD dip switch is that the common end is connected to P1.1 and P1.2, and 8421 is connected to P1.3~P1.6

MCS-51 series microcontroller control register TCON (88H)

The high 4 bits of the special function register TCON are the timer operation control bit and overflow flag bit, and the low 4 bits are the external interrupt trigger mode control bit and latch external interrupt request source. The TCON format is as follows: D7 D6 D5 D4 D3 D2 D1 D0 TF1 TR1 TF0 TR0 IE1 IT1 IE0 IT0

51 MCU's printf and other format output functions

When using the printf function and sprintf function on the 51 microcontroller, pay attention to the following points: 1. The format character of unsigned 16-bit data is %d or %u. Do not add the letter "l", otherwise an error will occur. 2. The format character of 32-bit data must be preceded by the letter "l", other

Why does the MCS-51 microcontroller need to interrupt the system expansion? How does the timer serve as an external interrupt source?

Why does the MCS-51 microcontroller need to use interrupt system expansion? Answer: Although MCS-51 has provided two external interrupt request input terminals INT0 and INT1, when there is still a large demand for external interrupt request sources, interrupt system expansion is required. When the timer is used as
