LCD KeyPad Shield: using ICSP connector for custom display output

Customer:

I’m working on a project where I need to occasionally change a temperature value - specifically, I need to set a temperature value in the code without uploading the entire program again. For example, I want to change the target temperature for a heating element (sometimes 50 degrees, sometimes 60 degrees, etc).

Pozdrav. Radim na jednom projektu kod kojeg bi trebao ponekad promjeniti vrijednost temperature tj da nekako u kod ubacim neku vrijednost temperature a da nije upload čitavog coda ??

Npr. da mijenjam vrijednost temperature do koje će neko grijaće tijelo da grije ( nekad 50 stepeni , nekad 60 … itd ).

Nadam se da ste me razumjeli.

Hvala

That looks like what I need, but I have an LCD with buttons and there are 6 pins labeled ICSP. Can I use this connector to output values and messages that I set in the code?

Original message (Croatian)

To bi bilo to , samo što je u mene lcd sa tipkama i ima još nekih 6 nožica kod kojih piše ICSP , da li ovaj konektor mogu kako iskoristiti za ispis vrijednosti i poruka koje zadajem u kodu ?

Hvala

Is your display a TFT or LCD? Can you provide a photo? This involves serial SPI communication: http://cdn.instructables.com/FR9/HXLZ/GAPV8IA4/FR9HXLZGAPV8IA4.MEDIUM.jpg We’ll need a photo to help you with the correct library for your display.

Vaš ekran je TFT ili LCD? Može li slika.
Inaće radi se o serijskoj SPI komunikaciji: http://cdn.instructables.com/FR9/HXLZ/GAPV8IA4/FR9HXLZGAPV8IA4.MEDIUM.jpg
Ipak će nam trebati slika da Vam pomognemo oko biblioteke koju ćete koristiti s ekranom.
