Matrix user forums

Hello!

I thought there is a little quiet here in the forum, is everyone on vacation

Well ok, maybe I can make a wake up

Now I see that the ST7789 display i s added to the component in FC8 so I suppose it is ok I report a bug. Finally I get my display and I made a test, but as Martin also mentioned here: https://www.matrixtsl.com/mmforums/view ... 77&t=22377

It doesn´t work.

Hopefully MM/Ben have time to have a look .

Hi Jorgen,

I think the Adafruit version has a slightly different initialisation...
Sorry - haven't had time to work with this lately, but will get round to it soon(ish) hopefully..

Hi Martin!

Ok, No rush. But I like this tiny coloured display. I made a test with the Arduino ide, and it work fine.

Look forward to see it work in FC8.

Thank`s Martin.

Hi again Martin!

Some more info maybe it can help

I have made some reserch on the web and I have downloaded a project from here with a temperature DS18b20: https://www.youtube.com/watch?v=-nECx4DOE84

First I follow his project step by step. Get the lib. and all. Follow his connection, power 3.3V and connect the datapin directly to the output, 5V. Damaged the display, it doesn´t work. I search some more and see different opinions how to connect the datapin. I try with resistor divider, no luck. then I try with only 2k7 resistor in serie only on data pin, then it work and is very nice and stable.

Subsequently I perform test with FC8 again, but no luck Of course I could use the others projects, but prefer to make my own in FC

One more thing, the name of the pin on the display fit, but not on the delete pin on the display, is this in FC8 CHIP SELECT?

Hello,

I've remade the component with a reset pin on the other topic.

As for the CS pin please assign this to an unused IO pin.
