I have decided to convert these tutorials into C. Mainly because there are hardware designs available.
The original designs and code are on Nigel's site.. http://www.winpicprog.co.uk/pic_tutorial.htm

Chip used in following tutorials "pic16f628a"
There is 9 tutorials in Lesson 1 (tutorial_1_C.zip)
There is 4 tutorials in Lesson 2 (tutorial_2_c.zip)
And 3 in lesson 3 (tutorial_3_c.zip)
Lesson 4 has only two (tutorial_4_C.zip)
Chip used in tutorial 6_7 is pic16f648a
Chip used in tutorial 7_7 and tutorial 8 is pic16f876a

I have finished and tested these tutorials and have tried to mimic the original ASM routines as best as I can, however due to slight language differences some parts MAY need explaining.

As soon as I complete a lesson I will upload the completed code.

I have written a basic explanation of the C components as it may be a little over some newbies heads.
( tutorial help.C )

The chip used is the same as the original tutorial ( Its mentioned in the asm code).
the compiler is Hi-tech lite v9.6 (shipped with MPLAB)

I have finished tutorial 5.. reading / writing IR using sony remote... But I need to get a ir transmitter and receiver
so once I've tested it I'll submit it.. OK I have checked this... Only two reading a remote... and being the remote.

It would be easy for someone to include an eeprom routine for the third example from Nigel..

There is now a little tutorial on the use of pointers that I have used in the tutorial remakes! Just to give an insight as
to why they are used.
( Pointers.c )

I've just finished the software I2C tutorial 1 but I need to re-read the originals as they appear to be VERY similar.

Nigel's tutorial 6 has 7 routines but for the purpose of C we really only need four.
I use 128k and 256k memory chips and writing to these chips are explained in the tutorials

tutorial 6_1 shows random access single byte addressing
tutorial 6_2 shows sequential access multiple byte addressing
tutorial 6_3 shows sequential access reading and writing the PCF8583 RTC.
tutorial 6_4 shows multiple eeprom access addressing single, multiple and strings.
I have gone the full hog and done tutorial 6_7 this is a data logger using the pcf8591 adc
and a smaller 24lc128 eeprom.
tutorial 7 1 through 6 are on the pic16f628a and are software serial routines output
to PC, LED's LCD etc...
tutorial 7_7 is on the pic16f876a, this is hardware serial PC and LCD output
I have kept the pic16f876a at 4mhz for this tutorial.

Tutorial 8 is hardware PWM on the pic16f876a.. There is only one tutorial.

Because C isn't as efficient as assembler the tutorial 6_7 will not fit onto a pic16f628a so
I had to upgrade to the slightly bigger pic16f648a.. As the tutorials from now on are written for
the pic16f876 you could use this board instead.

Tutorial 9 is on the pic16f628a and uses the hex key pad.
9_1 will display a keypress in hex and ascii on an lcd screen
9_2 will accept a 4 digit security code
9_3 is the same as 9_1 but output is via RS232 to a PC
9_4 is a IR transmitter but as its untested I will not upload it.

One file in tutorial 10... Dual seven segment display ( common anode )
This example uses interrupts on timer 2 to refresh the display.

Tutorial 11 is for ADC input on AN0 and AN1 using LCD and RS232 output
Tutorial 11.1 reads ADC channel 0 and displays the decimal and hexidecimal values
on the LCD
Tutorial 11.1a is the same as 11.1 but uses sprintf() to display hex values.
Tutorial 11.2 reads two ADC channels, 0 and 1 and displays on the LCD screen.
Tutorial 11.3 reads ADC channel 0 and displays as volts to 2 decimal places.
Tutorial 11.4 is the same as 11.3 but also outputs to a PC via RS232.

Tutorials 13 are based on the pic16f877a
Tutorial 13.1 Matrix of 8x8 led... inverting a square shape
Tutorial 13.2 Scrolling numbers 0 through 9.. left right up and down
Tutorial 13.3 Scrolling a text message **** NOTE **** the tutorial also includes
a file "fnt.c" This is the ASCII set in bitmap form (just include it in the build
in tutorial 13.3)

Tutorials 12 are based on the pic16f628a
Right!! Tutorial 12.... I have implemented Manchester encoding / decoding on basic serial
output... As I have never used this before (I use XRF & Xbee ) the transmitter and receiver
codes are included, just for an example... You will need to implement your own protocol.

Most RF device now have all the encoding / decoding done automatically


If anyone finds a BUG!!! please let me know... Also if there is something else that should be
in the tutorial.. I'll try and incorporate it...
