The x values for NAP are as follows: Enviado por caetano apostjla Denunciar. The compiler will always tell you when you have a conflict. Enviado por caetano flag Denunciar. For defining unique variables: The text following ‘DATA’ is usually a list of bytes which can be constant expressions. Reset will end STOP. High-Z speakers may be driven with a coupling cap and a filter cap. Adjusting the pot causes the returned value to go up or down. Milliseconds specifies how long to output the frequency s.

This allows you to change programs while keeping data, assuming both programs defined the same stretch of memory as undefined DATA. Here is an example DATA statement: Freq1 specifies the first frequency in microprocexsadores units Hz. Undefined data is the mere allocation of data space, while not assigning values into the bytes of EEPROM to be done at run-time, instead.

It is df by 1 for each byte declared.

MICROPROCESSADORES

The VAR usage options are as follows: Approximately 50ua average current will be consumed. PWM pin,duty,cycles Pin will be temporarily made an output while it is modulated. Duty is an 8-bit value which specifies the duty-cycle. END is terminated only by a hardware reset. The result will be microprocessadorws into variable. The default on and off times are ms and 50ms.

When done, pin will be placed in input mode to allow the voltage to remain until another PWM is executed. Alt-M is a quick way apistila assess how much RAM you’ve used.

For example, to convert a potentiometer setting to a number: Use Alt-M to see this. Defined data is fully declared and known at compile time. The pin may be filtered by zpostila RC circuit to achieve a clean sine-wave s. NAP x Enter low-power mode for a short period.

The pin may be filtered by an Dr circuit to achieve a clean sine-waves. STOP Execution is frozen, but low-power mode is not entered. Alt-M lets you see the result of this process. Your data, on the other hand, builds from the start of memory towards the end.

RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’. The CON syntax is as follows: The resistor-cap junction will reflect the duty V during and after PWM. The symbol name will be assigned a constant value as if via CON which is the current data pointer. This allocation is automatic.

A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS. This is handy micrlprocessadores having a single declaration which gets accessed throughout your program.

Here are all the variable modifiers: Defined and undefined data are declared as follows: Keep in mind that you may make alias names for the pin variables: DATA statements are used to build data into unused memory. Non-unique variables are microprcoessadores or in-part derived from unique variables and get assigned within the unique-variable memory.

Initially, the DATA location is set to 0.

The sum of program and data memory cannot exceed the 2K byte limit. Freq2 is optional and specifies a second frequency. It may be microprocessadorres to place a series resistor to the pot to prevent a short from the high pin to VSS. In the above example assuming this was the first DATA statement in the program”table” becomes a constant symbol of value 0; “Here is a string
