IO port control

Direction register TRISA~TRISAE

For example, TRISB=0x00; // 1 is input, 0 is output, so all portB ports are set to output

Data register PORTA~PORTE

For example, PORTB=0x01; // 1 is set high, 0 is set low, so portB1 is set high and other portB ports are set low

Example: Lighting program

#include

__CONFIG (0x3B31); // PIC microcontroller needs to configure registers, see the manual for details

void main()

{

TRISD=0xfe; // Set RD1 port as output

PORTD=0x01; // Set RD1 port high

//RD1=1; PORTD is the same as RD

while(1);

}

PIC interrupt special instructions

During the debugging of the W660-MODBUS product, I found that the program would work abnormally under occasional circumstances. After nearly a week of tracking, I found that the PIC interrupt had the following two strange characteristics: The interrupt flag should be cleared when the interrupt is just entered. If th

Battery monitoring circuit using PIC12C508 single chip microcomputer

12v Lead Acid batteries used in trucks, cars, RVs and uninterruptible power supplies are usually rated at 12V. This circuit monitors the battery, the charge and discharge curves, gives the current voltage value and predicts the time left until the power supply ends. The voltage of a 12V battery is 13.
