Lines of assembler source code may be placed anywhere in basic source program and must begin with ASM: prefix. The compiler is able to compile all possible complex arithmetic expressions. Arithmetic operations are allowed only in assignment statements and all variables in one such statement must be the same data type.

It is possible to make only one logical operation in one single statement. Logical operations are allowed only in assignment statements. It uses line label name as argument. Line labels can be global or local. Line labels must be followed by colon mark ':'. There are no limits for the number of nested statements of any kind.

They can be used with integer constants and also with variables of Short or Integer data type. User need to take care that the program structure is consistent. When using subroutines, main routine need to be ended with END statement. The first argument is a Short variable that will be the target of the operation, and the second argument is target bit number and it must be a constant in the range Individual bits of a Byte variable can be addressed by.

Keywords True and False are also available for Bit type constants. If the argument of these statements is a bit in one of the PORT registers, then the same bit in the corresponding TRIS register is automatically cleared, setting the affected pin as an output pin. The compiler is able to compile all possible complex arithmetic expressions. For Bit data type variables seven logical operations are available.

It is possible to make only one logical operation in one single statement. Logical operations are also available for Byte and Word variables. These parameters should be setup at the beginning of the basic program. Its first argument is the address of the first byte in the data list. The GOTO statement uses line label name as argument. Line labels must be followed by colon mark ":". It is also possible to use variable argument of Byte or Word data type. These routines use Clock Frequency parameter that can be changed from the Options menu.

Many examples in this help file also use such 'real-time' intervals. But, if you want to simulate those programs you have to be very patient to see something to happen, even on very powerful PCs available today.

For simulation of 'WaitMs ' statement on 4MHz you have to wait the simulator to simulate instructions and it will take considerable amount of time even if 'extremely fast' simulation rate is selected. So, just for the purpose of simulation you should recompile your programs with adjusted delay intervals, that should not exceed ms. But, be sure to recompile your program with original delays before you download it to a real device.

There are no limits for the number of nested statements of any kind. LOOKUP function can be used to select one from the list of Byte constants, based on the value in the index Byte variable, that is supplied as the last separated argument of the function. The first constant in the list has index value 0. The selected constant will be loaded into the result Byte data type variable. If the value in the index variable goes beyond the number of constants in the list, the result variable will not be affected by the function.

If all constants in the list or part of them are ASCII values, then shorter form of the list can be created by using string arguments. The first argument is input variable and the second argument is number of shifts to be performed.

Structured programs can be written using subroutine calls with GOSUB statement that uses line label name as argument. User need to take care that the program structure is consistent. The Microchip PIC family of microcontrollers is the most popular series of microcontrollers in the world.

Program consists of a sequence of commands written in programming language that microcontroller executes one after another.

Compiler is a program run … The author then discusses programming the most common version of the PIC microcontroller, the 15F
