PIC Based Temperature Data Logger

Here's a PIC based temperature data logger. The PIC used is 8-pin PIC12F683 and the temperature sensor used is DS1820 that doesn't require calibration and provides temperature value in digital format. This temperature logger records data inside the internal EEPROM. Each temperature value is 8 byte, so the resolution is 1 degree C.

Besides, the sampling interval is user selectable (1 sec, 1 min, or 10 min). The recorded values can be sent to a PC through a serial port.

Interface 16x2 LCD to a PIC microcontroller using C

Liquid crystal displays (LCDs) are more convenient ways of displaying output results in any microcontroller based projects. If you are new to microcontroller interfacing, and want to learn how to interface a LCD to a PIC microcontroller you need to look at this. Here you will find PIC16F628A interfacing with a 16x2 LCD display and the programming is done in mikroC.

The objective of this experiment is to interface a 16x2 LCD to PIC16F628A in 4-bit mode. This means the data transfer

will use only four pins of the microcontroller. There is no additional hardware setup needed for this experiment, as we have a ready-made LCD interface female ......

Learn PIC Programming in mikroC

If you are looking for online resources for learning PIC Programming in C, then you should probably check these two blogs:
1. http://pic16f628a.blogspot.com/
This blog starts with making your own PIC16F628A Development Board, and then teaches you basics of microcontroller interfacing by doing various experiments. The language of programming is C and the compiler used is the demo version of mikroC. The board has following features:

• Access to all I/O pins through female header pins
• 4 Push Buttons for Input
• 4 LEDs for Output
• An LCD Interface Port
• A 4-digit Seven-Segment Display Interface
• LCD Backlight Switch and Contrast Adjustment
• ICSP Programming (Very Important)

This is another blog that teaches you about PIC12683, a 8-pin microcontroller from Microchip. The writer again starts with making his own development board, and uses mikroC for doing experiments. The board has following features:

1. A Regulated +5V power supply.

2. 3 Red LED outputs which can be connected to any GPIO pins using jumper wires.

3. An ON/OFF power supply switch.

4. A Green LED as a power ON indicator.

5. An 8-pin IC socket for PIC12F683 microcontroller.

6. Two potentiometers: one for providing Vref, and other for simulating analog input to ADC.

7. An ICSP header connector.

8. Two tactile switches for input operation.

9. A TTL to RS232 level shifter using a transistor circuit.

10. A piezo buzzer.

11. A DC motor with driving circuit.

12. Access to individual pins of PIC12F683 through female header pins.
