PIC16F19156

[JLeith]

Hello
I'm using Flowcode 6 and I need a PIC16 with higher ram for a OLED display project

I selected PIC16F19156 for the task but I can't find the chip (Build - Find Target)

PIC16F19156 I/SP-ND from DigiKey

Hi John,

We currently do not support this device, even in Flowcode 8. I could look at adding it into v8 if that would be useful.

I'm afraid that the compiler shipped with Flowcode 6 will not support this chip.

Hi Benj

That is a sad time. I would of thought PIC16 family would cover all chips or at least have a update to Compiler.

The chips arrived this morning $16 dollars down the drain

Benj do you happen to know a 28pin chip with SRAM Byte 2048 ?

I have a SSD3106 OLED display that needs more memory other then 1024.

The PIC16F family in Flowcode 6 all work work with my Compiler ?

Hi John,

Benj do you happen to know a 28pin chip with SRAM Byte 2048 ?

Looking at devices Flowcode 6 supports then what about 18F26K80?
It has 3.6K of SRAM which is over 1K more than PIC16F19156.
You can't program the newer devices with PICkit 2, without a resistor in series with VPP.
Maybe best to use PICkit 3/4 or mikroProg for PIC, dsPIC, PIC24, and PIC32.
It's not PIC16F but I'm using an 18F chip to drive a 5in resistive touch LCD and its works brilliantly!

Thank you Martin.

Let me try the PIC18F26K80 and see if my program will complies to hex.

Back in a few minutes

Hi Martin
I was able to select the PIC18F26K80 it didn't like my use of A4.
Has a internal OSC.

It compiled to Hex. Hurray...

Did get some cautions.

Caution: argument of 'delay_us' calls must have a value of 1 or more
Caution: Delay inaccurrate: 'delay_us', Delay overhead:0ms, Unit delay:0.00101725ms, Delay resolution:1 units

Here is my OLED project. Flowcode

Take a look at this post

Glad it compiles for you that is promising.

Morning Martin.

Thank you for the info on the "Caution". New beginnings for me in the PIC18 world.

John

[medelec35]

Hi John, not just for the 18f world but same applies to the 16f world as well.

Hello Martin
My new PIC18F26K80 arrived and I started the design for a OLED display

I tried to load the PIC18 and it fails code 36

Check my connections all look good.
Here is a mock up of the board.

I listed the NFR905 wiring as black leads and the OLED

The error says it cant find the PIC ?
suggestions

Thought maybe my PICKIT2 won't load a PIC18F26K80

I tried doing a Hex load with Pickit 2 and it could not find a PIC18F26K80

Does this mean I should purchase Pikit3

John

[JLeith]

I see the Pickit 3 at Microsoft is $47.95

And there is a Pickit 4 in the market for $47.95.

Not sure if I need to upgrade should I get the 4 or 3 version. seeing they are the same price ?

John

[Benj]

Hi John,

Wow that's expensive! I remember when you could buy the PICkit 3 with a nice dev board for £18.

The PICkit 4 is likely more future proof. I have used one but nowhere near as much as I have used a PICkit 3 so it's hard for me to make a good call.

[JLeith]

Hello Benj

Thank you for responding to my latest wow as me.

I think I will go with the PicKit 3 seeing that appears to be the most common.

I found on for sale on Amazon Prime £17.73 or $29 cdn.

Now my next mountain to climb. It only comes with the PicKit3 interface.
No CD.

Benj do you know where I can get the Software and I recall the mess I had getting my Pickit2 settings
It took 3 weeks to find the settings when I had to get a new laptop.

Once I find the software to download I will purchase the new PicKit3 from Amazon.

Thank you

Hi John,

Good find, that sounds like a better price!

You need MPLAB X and when installing make sure that the IPE option is ticked, this is what Flowcode uses and also allows you to program stand alone.

Flowcode details are here.

Or go to the Flowcode wiki and search for PICkit.

Hello Benj

Thank you so much for the help.

I have placed my order for the PicKit3

I will let you know how it goes.

John
