SainSmart 1.8 &#34;couleur TFT LCD Module avec interface SPI et MicroSD pour Arduino UNO MEGA R3

TFT acheté dans le but d'afficher des données via Arduino. L'utilisation est simple, il suffit d'importer les librairies et d'écrire le code. Dans mon cas, affichage données de température et humidité.
Le seul bémol sera la finition limite : l'afficheur se décolle du PCB. Rien de grave, un peu d'époxy est le tour est joué.
Bref, rien de surprenant pour le prix et fait très bien le job.

Sympathique mais difficile à prendre en main

J'ai reçu cet écran très rapidement il n'y a donc aucun problème de ce côté-là. Cependant, il a été difficile de le faire fonctionner : l'écran restait obstinément blanc. Pour le faire fonctionner sur mon arduino mega 2560 SainSmart, j'ai utilisé ce tuto là :

Le code que j'utilise est disponible ici :

Works.

I manage to make it working on a Arduino and a Raspberry but... lots, lots of hours looking Internet, looking examples, trying....
Would be perfect if the seller send/give some programs that works out of the box!

Arduino prend de la couleur !

Petit écran bien sympatique. Branchement simple. Pour rajouter un peu de couleur à Arduino ! Les librairies sont faciles à trouver sur Internet. Content !

Perfectible...

L'affichage en lui-même est parfait.
Je mets seulement 2 étoiles en raison de la finition du produit.
En effet, la dalle de l'écran s'est très vite décollée du support...

Un petit point de colle chaude et on n'en parle plus, mais pour le prix un petit effort de finition serait appréciable.

Ne marche déjà plus...

Commenté en France 🇫🇷 le 15 juillet 2014

très content aux premiers abords, j'avais pu faire marcher l'affichage avec un Arduino Mega sans trop de difficulté.
Ayant voulu refaire des essais avec ce soir, l'écran ne fonctionne plus. Bien que le rétroéclairage se mette en route, plus rien ne s'affiche... pourtant, même code, même montage que précédemment...

Nice little display

Commenté au Royaume-Uni 🇬🇧 le 12 juin 2017

Nice clear little screen, once you get it going. The screen is roughly 32mm high by 37mm wide. I assumed it was a standard landscape display but it actually displays in portrait, which took me by surprise. As it turned out this actually worked for me.
I did find the display a bit small for my purposes but that was my fault for not checking the size.
There is a link to a .rar file to unzip with libraries & examples but the instructions are a bit vague & for a novice might put them off . Having a .zip file would have been better as the Arduino IDE would manage the installation.
I got a couple of problems using the example programs.
I found that the connection pin idents on the board differed from what was written in the example code. A minor irritation.
I tried to use the examples directly & I got compilation errors.
(1) I found I needed to edit ST7735.h, changing WProgram.h to Arduino.h.
(2) I had to edit glcdfont.c - I changed
static unsigned char PROGMEM font[] = {
to
const unsigned char PROGMEM font[] = {.
(3) in their graphicstest program some of the colours were swapped over; Red & Blue were swapped as were Cyan & yellow. Fairly easy to swap the values over.
After that everything compiled OK.
I tried this on an Arduino Nano I had it to hand & I ran into trouble with lack of memory. The examples are pretty hard on memory resources. I tried it on an Arduino Mega & it ran OK. I should say that I've only tried it so far using the software SPI configuration. In the examples it does reference both the hardware & software SPI with the hardware version commented out.
The example programs are quite effective at demonstrating the display's capabilities.These showed that the display could display both text & graphics
Modifying the graphicstest example program, I found that the display was roughly 16 lines high by about 21 characters wide & was easy to read..
There are other similar looking displays on Amazon that are half the price but don't have any documentation or library support.
I've used Sainsmart for Arduino boards, LCD displays & other things & found the goods work well & the quality seems to be of a consistent high standard.They aren't the cheapest but I guess you have to pay for the consistency & quality one way or another.
I would sum it all up by saying the display is very nice, but the documentation could be a little better & the examples need to work "out of the box".
Would I buy it again? If I needed something that small, yes.

Not Sure

Its amazing ... but not a "1st screen buy"

Commenté au Royaume-Uni 🇬🇧 le 10 mai 2014

Its a beautiful tiny screen ...
But be careful when handling for the 1st time, the screen might flop away from the back PCB & may swing on the ribbon cable violently, without warning

I disagree strongly with others saying that the header pins do need to be moved ... Why not use some double sided sticky black foam strips & a sheet of perspex, add touch dirt & shock protection will set the screen back a few mm removing the headers from contact with the project box walls, problem solved & still keeps it great for the breadboard

1st time TFT buyers be aware
Personally for me Im having coding problems, i can understand tutorials but am none the wiser on the coding side ... i have installed a number of recommended libraries, have ran a few demos (only can run low speed) & have managed to manipulate someone's code with great difficulty to just show a value of a sensor on a voltage divider circuit, nobody is showing me a list of commands or pointing me in the right direction to use a particular library for a particular screen or create a library for this screen to use it with my own initiative ... Iv found myself just following orders & its not helping ... maybe another choice of a 1st arduino or/& Raspberry Pi screen will educate enough to start using this screen ... this may not be a "1st time screen buy"... or maybe im just useless HaHa
Buy it though, it might do your head in enough to keep on pushing ... like me ;)

beautiful, once working

Commenté au Royaume-Uni 🇬🇧 le 12 août 2013

Be aware that the colour of the tab on the screen protector (black/red/green) is your only indication of which set of (slightly different) hardware is in this module. Take a note of it and configure your SPI library appropriately.

Note also that the pin configuration is different from the adafruit equivalent.

That said, with a little googling and hacking I got it to work on Arduino, and, after compiling a custom kernel with tftlcd & ST7735R support, a Raspberry Pi. Note that simply building a kernel module is insufficient -- the stock raspbian does not support it. You could probably drive it directly via SPI for some applications ( rather than trying to use it as a monitor ). This might make more sense as it is rather small (but the Raspbian desktop does look very cute on it...)

It is a beautiful little screen.
