DS1820 library, suitable for the DS18(S/B)20 and equivalents.

LM35 library, without float calculations, so code size effective.See the package content for the documentation.


  The zipfiles have the same content as the packages, except that the mikroBasic version is also present in them.

===============================================================================
2012-11-12: The microBasic package(s) ha(s)(ve) been added.

Only the .mcl files are available as "library" files: they are copied from the mikroPascal version (the mP and mB .mcl files are compatible - luckely - ).

If you want to see some sources: look into the mP versions.

The example files are still in mP, not in mB. (I do not have an mB licence, so I can not compile them).

Some of the helpfiles are also still referring to mP, but all library "interfaces" are available in the mB language.

--------------------------------------------------------------------------------------------------------------------------------------------
2013-01-26:  Replaced "Delay_ms" and "Delay_us" by routines available in the Delays lib.
"Delay_ms" and "Delay_us" are inline routines and cannot be used in libraries if they are to be used without source (e.g. non Pascal compilers).

---------------------------------------------------------------------------------------------------------------------------------------

Version 2.0 (2013-10-23): Added the routine "DS1820_TempConversionReady". The purpose of this routine is to replace the fixed waiting time needed after "DS1820_StartTempConversion" by a "ready" measurement. The latter method will result in shorter waiting times than the fixed one of 750 ms.

----------------------------------------------------------------------------------------------------------------------------------------

Version 3.0 (2013-10-28): Added the "Parasite Power" capability.

-------------------------------------------------------------------------------------------------------------------------------------- 2013-10-29: Corrected an error in the waiting time during conversion of the "DS1820_StartTempConversion_.._PP" routines. The delay used was 10 times too short. Sorry for the inconvenience caused by that.

---------------------------------------------------------------------------------------------------------------------------------------

Version 4.0 (2013-11-06):

- Added the "DS18B20_TempToString_HR" procedure. Resolution is 9-12 bits.
- Changed the "DS1820_StartTempConversion_.._PP to make variable waiting time possible
- Added ClrWdt while waiting during temp conversion
- Added the DS1820_Family function.
- Added the procedures "DS1820_SetConfiguration", "DS18B20_SetConfiguration",
   "DS1820_SetConfigurationROM" and "DS18B20_SetConfigurationROM",
   "DS1820_GetConfiguration", "DS18B20_GetConfiguration",
   "DS1820_GetConfigurationROM" and "DS18B20_GetConfigurationROM"

--------------------------------------------------------------------------------------------------------------------------------------

2013-11-12: Added a small correction to the "read bit" parts in some of the routines. Nothing essential.

-------------------------------------------------------------------------------------------------------------------------------------- 2013-11-18: Added the PIC24 versions.

--------------------------------------------------------------------------------------------------------------------------------------

2013-12-18. Changed the signature of the routine "DS1820_Family_ROM".

-------------------------------------------------------------------------------------------------------------------------------------------

2013-12-27: Added the routines "DS1820_ReadTemperature_Fast" and "DS1820_ReadTemperatureROM_Fast". They only read the first 2 bytes from the DS1820 scrathpad, so they need less time.

---------------------------------------------------------------------------------------------------------------------------------------- 2014-03-13: The mikroBasic files and zip files have been updated. All mB sources are present now (not tested if compilable though).

-------------------------------------------------------------------------------------------------------------------------------------- 2014-05-16:

- Simplified the "DS18B20_TempToString_HR" procedure: smaller code, better time performance  and one parameter ("Resolution") removed. The latter proved to be not necessary.
- Removed the writing to EEPROM and Reading from EEPROM in the "xxx_SetConfiguration" and    "xxx_GetConfiguration" routines.

--------------------------------------------------------------------------------------------------------------------------------------

2014-05-30: The LM35 library has been added to the package.


2015-01-26: Replaced the mB files: all mB files are compilable now (which e.g. means that all "with" statements are dealt with). I could however not link and test the libraries (no mB licence).


2015-06-27: Changed the PIC24 libraries: the "simple" routine for 5V has been deleted.


2015-07-18: - Changed "DS18B20_SetConfiguration..." to the spec of the "configuration" byte. No functional change.
            - Added the routine "DS18B20_ResetUnusedBits" for the DS18B20 when used at a lower resolution than 12 bits, see the spec sheet.

------------------------------------------------------------------------------------------------------------------------------------------------
2018-02-24: made the CRC checking routines smaller and more understandable.

Thermostat with DS1820

5

Usage of the Ds1820 (one wire temp sensor) to control a heating system. Provides 2 different temp settings (e.g. day and night settings). Proportional control of the heater (which is basically on/off controlled) using PWM like method with a 1 minute timebase (x minutes on, y minutes off).

WattMeter (Power meter)

5

This project is a power meter (Wattmeter). It is made for 230V~ (nominal, rms), 2.5A~ (max, rms) and 50Hz, but is rather easily adaptable to other voltages, currents and frequencies. It can handle both sinusoidal and non sinusoidal voltages and currents, both with and without DC component.

PIC Command Line Editor

5

Capable of, like a modem, receiving, editing and executing one (command) line of input. The code in this example project shows a command line editor that can be used in servers (big word) you build, based on PICs.
