This tutorial covers about 35 to 45 areas of Baseline assembler.

If somebody does the Midrange assembler lessons also.

You end up with sort of a 'PIC Toolbox'..

A concise knowledge of what can be done with a PIC.

If you want to 'fly by the seat of your pants'.

Armed with this knowledge you can just pick out your 'tools' and go at a project.

Just 'get it done'.

Anybody else look at PIC's this way?

What way?

 

Armed with this knowledge you can just pick out your 'tools' and go at a project.

You have a problem to solve, you look at the tools you have and your skill in using them.

The desired project usually comes first.

No.

 

Thank you

Okay.

That's the way I'm starting to look at it then.

You can pick up the Datasheet or these tutorials.

Then for example find 'Serial Communication'.

'I'm going to add serial communication to my project.

Not everything being covered in tutorial is something you are going to use every program you write

 

You can pick up ... these tutorials.

What tutorials?

 

Thank you Joey

Gooligum.

Each lesson covers 3 to 4 topics.

 

Thank you Joey...

You're welcome. But I still have no clue as to what you are talking about.

 

Thank you Joey

IF you have information about how to use a PIC.

A datasheet for 10F200 let's say.

You can look at it as a 'toolbox'.

If you want to do something you look up the section in datasheet.

That section would be a 'tool.

Do you agree? Yes/No?

No. A datasheet is documentation. A hammer -- or an assembler -- is a tool.

 

You no if you really want do serial then forget 10f200 and 12f509 or 508 and use a chip like 16f1825 Or a 12f1822
The first 3 don't have serial has to bit bang it which I posted code that works on all 3 with little simple changes
The last 2 you can use MMC in mplab and be doing serial in no time flat. I2C spi ADC timers you name it but you got read the files.
Nice samples like this

void main(void) {
                                // initialize the device
                                SYSTEM_Initialize();
                                uint8_t data;
                              
                                // Enable the Global Interrupts
                                INTERRUPT_GlobalInterruptEnable();
                              
                                // Enable the Peripheral Interrupts
                                INTERRUPT_PeripheralInterruptEnable();
                              
                                printf("\t\tTEST CODE\n\r");        //Enable redirect STDIO to USART before using printf statements
                                printf("\t\t---- ----\n\r");
                                printf("\t\tECHO TEST\n\r");
                                printf("\t\t---- ----\n\n\r");
                                printf("Enter any string: ");
                                do{
                                data = EUSART_Read();        // Read data received
                                EUSART_Write(data);            // Echo back the data received
                                }while(!EUSART_DataReady);        //check if any data is received
                              
                            }

 

Thank you Joey

Okay.

We have two NO votes.

You and OBW.

Max seemed to be sitting on fence.

 

Thank you Bebe

Okay.

Made a another 'Forum mistake'.

That was just an example.

I am just saying tutorial covers 'Everything'.

When you write some programs you are not going to use 'Everything'.

Just beginning to notice that doing Tutorial.

 

I agree if you want serial on a 8 pin go with the 12f1822
.

You're welcome. But I still have no clue as to what you are talking about.

Max.

 

Thank you Max

That was just an example.

Pretty sure tutorials will get to serial communication.

 

Nope He didn't make one

 

Thank you Bebe

Been taking a break from the tutorial.

Lesson 7 is up next.

Yep. He may not cover some of the 'combined' type subjects.

Where it's a whole lot of pieces put together.

We'll see.

 

Its good to start with PIC's and assembler, "walk before you run " theory worked for me . I would take .asm examples and modify them , tried many PIC16F devices. The main tool you need to understand is MPLAB SIM ... single step and watch the registers, check the program flow, a tutorial is just the authors way of doing things there are many ways to skin a rabbit Hardware .... a simple bread board / strip board + programmer set up will do. Main thing have fun.

 

Thank you TQFP 44

'Its good to start with PIC's and assembler'

We are in a minority. Wish I had $20 for how many times I've heard

'Get a 18F blank. Get a 32MX blank.Start out with a cutting edge PIC'

 

Tqfp44 that's very true there is 100 of ways to do the same thing but just writing code and see what it does is the best and the sim is a great tool to see what happens.
Hopping around don't really work well get lost that way.

What get's me about tutorials is there not like you said the only way some not even close because there not clearly laid out.
Like the arduino you can read a 100 to do the samething and haft have left out the main parts.
The data sheet from the pic read it try getting the pic to work was the best way for me and seeing it happen with the sim.
I wanted serial with the 12f508 I found some code in C for a 8080

second 8-bit microprocessor designed and manufactured by Intel and was released in April 1974

I spent a week with the datasheet and the code works great I posted it 8 years ago and and got maybe 5 people showing the take of bit bang serial and there's worked too. It's got be fun I like my fun just doing it.
serial bit bang for chip without serial.
