The following is an example of a simple initialization of an STC microcontroller. For this example, let's assume that you are using a STC89C52RC microcontroller and using the Keil C51 compiler.
include the header file of the STC89C52RC microcontroller
void delay(unsigned int count) is a simple delay function
while(count--)
void timer0 init() timer0 initialization function
tmod |= 0x01;Set timer0 to mode 1 (16-bit timing counter).
th0 = 0xfc;Set the initial value of timer0, and calculate the specific value according to your needs
tl0 = 0x67;Set the initial value of timer0
et0 = 1;Timer0 interrupt is enabled
tr0 = 1;Start timer0
void uart init() serial port initialization function
tmod |= 0x20;Set timer1 to mode 2 (8-bit auto-reload timing counter).
th1 = 0xfd;Set the serial port baud rate, which is assumed to be 9600bps
scon = 0x50;Serial mode 1, allowing receiving
tr1 = 1;Start timer1
ti = 1;Set the send flag
void interrupt init() interrupts the initialization function
ea = 1;Enable global interrupts
es = 1;Enable serial port interruption
et0 = 1;Timer0 interrupt is enabled
void main() main function
uart_init();Initialize the serial port
timer0_init();Initialize timer0
interrupt_init();Initialization interrupts
while(1) main loop
The above is just a basic framework, and the specific application needs to be written according to the needs of your project. You can use this template to add additional peripheral initialization and functionality**. Note that when using the STC microcontroller, you may also need to add some special initialization**, such as setting the clock frequency of the microcontroller, etc. When writing, make sure you understand the characteristics of the microcontroller you are using and the function of the registers. In addition, for the Keil C51 compiler, you may also need to configure some compiler options, such as selecting the correct microcontroller model and target board settings.
