I am trying to use the rAdaFruit_ST7735 and rAdaFruitGFX libraries to use an OLED and display information about it.
The connections made are:
ESP ----------------- ST7735
D3 ....................... CS
D4 ....................... RST
D2 ....................... RS
D7 ....................... SDA
D5 ....................... CLK
The code used is

Sub Process_Globals

Oled público como AdafruitST7735
CS_Oled público como pin
RTS_Oled público como pin
RS_Oled público como pin


End Sub


Attached picture of OLED ST7735
the result is that the OLED blinks but nothing is displayed.
Any help or example
Thanks
