For apodtila, to convert a potentiometer setting to a number: High-Z speakers may be driven with a coupling cap and a filter cap. Freq2 is optional and specifies a second frequency.

The result will be written into variable. Defined data is fully declared and known at compile microrocessadores. The symbol name will be assigned a constant value as if via CON which is the current data pointer.

It may be necessary to place a series resistor to the pot to prevent a short from the high dee to VSS. Enviado por caetano flag Denunciar. For defining unique variables: Alt-M lets you see the result of this process. Approximately 50ua average current will be consumed.



Milliseconds specifies how long to output the frequency s. Here are all the variable modifiers: The pin may be filtered by an RC circuit to achieve a clean sine-wave s.

The pin may be filtered by an RC circuit to achieve a clean sine-waves. Freq1 specifies the first frequency in 1Hz units Hz. Adjusting the pot causes the returned value to go up or down.

Alt-M is a quick way to assess how much RAM you’ve used. The resistor-cap junction will reflect the duty V during and after PWM.

The x values for NAP are as follows: Use Alt-M to see this. DATA statements are used to build data into unused memory. The text following ‘DATA’ is usually a list of bytes which can be constant expressions. Duty is an 8-bit value which specifies the duty-cycle.

Defined and undefined data are declared as follows: STOP Execution is frozen, but low-power mode is not entered. Here is an example DATA statement: 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.


Initially, the DATA location is set to 0. It is advanced by 1 for each byte declared. Reset will end STOP.

RCTIME pin,state,variable Pin will be placed in input mode and time will be measure in 2us units while pin is in ‘state’. This allocation is automatic. Undefined data is the mere allocation of data space, while not assigning d into the bytes of EEPROM to be done at run-time, instead.


The default on and off times are ms and 50ms. The compiler will always tell you when you have a conflict. The VAR usage options are as follows: When done, pin will be placed in input mode to allow the voltage to remain until another PWM is executed.
