Now, this morning, i did some fast tests on wemos nodemcu 3.0 and looks that it´s working, not reset during run, reset or power up.
But i didnt connected the lcd in this module yet.
The older module was nodemcu 1.0.
Let me know if your test works (havoc).
And try to reduce the SPI speed for a while!

Hello,

I am using a D1 Mini NodeMCU Lua ESP8266 ESP-12 WeMos D1 Mini WIFI 4M Bytes
In the Adafruit library I noticed that bitmaps can be scaled by an integer,
Since espbasic only uses scale=1, I eliminated the extra code,
The code runs a bit faster now, but still craches
Maybe because the transfer are now a bit faster, the breadboard is playing havoc to the signals/power supply,
I will try to remove from breadboard and use seperate power supply for the display
Will keep you posted



regards,

I will try with a BETTER POWER SUPPLY late!

For me still reset sometimes when power up, reset or RUN.

Can you send your circuit picture ? (esp+tft)

Are you powering the tft with the power 3.3v coming from ESP ?

- Thu Sep 08, 2016 6:53 am #54680 Now i am using a professional power supply!

And i have changed from NODEMCU to OLIMEX board.

Unbelievable, i still having the same problems, when i try to run, reset or power up, sometimes the ESP8266 crash

Can i change the SPI speed used to communicate with TFT TOUCH ?

Where in BASIC or C CODE ?
