Reset will end STOP. Enviado por caetano flag Denunciar. END is terminated only by a hardware reset. The pin may be filtered by an RC circuit to achieve a clean sine-waves. The result will be written into variable. The x values for NAP are as follows: DATA statements are mmicroprocessadores to build data into unused memory. Alt-M is a quick way to assess how much RAM you’ve used.

It may be necessary to place a series resistor to the pot to prevent a short from the high pin to VSS. For defining unique variables: Freq1 specifies the first frequency in 1Hz units Hz.

Adjusting the pot causes the returned value to go up or down. This allows you to change programs while keeping data, assuming both programs defined the same stretch of memory as undefined Microprcoessadores. Initially, the DATA location is set to 0. The compiler will always tell you when you have a conflict.


PWM pin,duty,cycles Pin will be temporarily made an output while it is microprocsssadores. Non-unique variables are in-whole or in-part derived from unique variables and get assigned within the unique-variable memory.

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 Here are all the variable modifiers: Duty is an 8-bit value which specifies the duty-cycle. This is handy for having a single declaration which gets accessed throughout your program. The pin may be filtered by an RC circuit to achieve a clean sine-wave s.

The CON syntax is as follows: Approximately 50ua average current will be consumed. Use Alt-M to see this. High-Z speakers may be driven with a coupling cap and a filter cap. Defined data is fully declared and known at compile time.


Freq2 is optional and specifies a second frequency. Keep in mind that you may make alias names for the pin variables: The sum of program and data memory cannot exceed the 2K byte limit. Defined and undefined data are declared as follows: The default on and off times are ms and 50ms. The VAR usage options are as follows: Milliseconds specifies how long to output the frequency s. Your data, on the other hand, builds from the start of memory towards the end.


The text following ‘DATA’ is usually a list of bytes which can be constant expressions. A digital-analog converter can be made by connecting the pin to a resistor which goes to a cap which goes to VSS.

Here is an example DATA statement: RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’. It is advanced by 1 for each byte declared.

When done, pin will be placed in input mode to allow the voltage to remain until another PWM is executed.


For example, to convert a potentiometer setting to a number: Alt-M lets you see the result of this process. STOP Execution micoprocessadores frozen, but low-power mode is not entered.

This allocation is automatic. NAP x Enter low-power mode for a short period.

The symbol name will be assigned a constant value as if via CON which is the current data pointer. The resistor-cap junction will reflect the duty V during and after PWM. Enviado por caetano flag Denunciar. 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.
