source code

PicBasic Pro program to demonstrate an interrupt-driven input buffer for hardware USART receive using assembly language interrupt.

source code

PicBasic Pro program to demonstrate an interrupt-driven input buffer for HSERIN using ON INTERRUPT.

source code

PicBasic Pro program for servo control using ON INTERRUPT. Uses TMR0 and prescaler. Watchdog Timer should be set to off at program time and NAP or SLEEP should not be used. Buttons on keypad are used to move servos.

source code

PicBasic Pro program to move RC servo 1 using keypad buttons. Button 1 moves servo left, 2 centres servo, 3 moves servo right.

source code

PicBasic Pro program to read and write to SPI SEEPROMs. Writes to the first 16 locations of an external serial EEPROM. Then reads first 16 locations back and sends to LCD repeatedly. Note: For SEEPROMs with word-sized address.

source code

PicBasic Pro program to demonstrate a method of storing text strings in a table. The strings can be called by storing the location of the first character in a variable and calling the strout subroutine. The string will be sent to both LCD and Serial pin and the main program will resume when the null terminating character is encountered in the table.

source code

PicBasic Pro program to read the DS1620 3-wire temperature sensor and display temperature on LCD.

source code

PicBasic Pro program to read DS1822 or DS18B20 1-wire temperature sensor using OWIN and OWOUT commands and display temperature on LCD.

source code

PicBasic Pro program to read DS1820 1-wire temperature sensor and display temperature on LCD.

source code

PicBasic Pro program to demonstrate the use of Timer1 interrupt for a real-time clock.

source code

PicBasic Pro program to create telephone pad tone. Note: LAB-X1 Oscillator must be set to 20MHz.

source code

PicBasic Pro program to measure voltage (0-5VDC) and display on LCD with 2 decimal places. A 60 segment bargraph is also displayed using custom LCD characters. This program uses the */ operator to scale the ADC result from 0-1023 to 0-500. The */ performs a divide by 256 automatically, allowing maths which would normally exceed the limit of a word variable.
