Timers, Counters and Interrupts

Definition and configuration of timer:

The counting register is composed of TH high 8 bits and TL low 8 bits-----------》T/C0 is TH0 and TL0--------------》T/C1 is TH1 and TL1

M1	M0	How it works	Functional Description
0	0	Method 0	13-bit timer/counter
0	1	Method 1	16-bit timer/counter
1	0	Method 2	Auto-reload 8-bit timer/counter
1	1	Method 3	T0 is divided into two 8-bit independent counters, T1 has no mode 3

Timer calculation initial value:

Problems in Keil application

There are several common warnings in Keil. Of course, compared with errors, the degree of warning is not as serious as the error. Sometimes, if you ignore it, unexpected errors will occur. Let's take a look at several common errors and analyze the reasons for them. 1. Warning 280:’i’:unreferenced local vari

Sorting out the various cycles in a microcontroller

Microcontroller clock cycle Clock period: The clock cycle is also called the oscillation cycle or the crystal oscillator cycle, which is the number of pulses emitted by the crystal oscillator per unit time. It is usually generated by an external oscillator. For example, 12MHZ=12×10 to the 6th power, that is, 12,000,

8051 MCU baud rate calculation formula (with C language routine)

The 8051 microcontroller uses timer 1 working in mode 2 as the serial port baud rate generator. Its baud rate = (2smod /32) × (timer T1 overflow rate), where smod is PCON 7 , indicating whether the baud rate is doubled, and Fsoc is the system crystal size. In the baud rate formula: T1 overflow rate = the inverse of
