Secondly did you upload and run pcd8543 example lua file in my first post?

Hi, Thanks for your reply.
I did not upload the lua file, I'll try that.
I saw somewhere that gpio 0/1/2 should work, but I can't find it right now. I'll dig around a little.

When flashing these files, will that remove any lua-files on the device?

Marius

no, just flash firmware and edit pins on pcd8543ex.lua and upload,run this lua file.

i pushed code in to the my github account. i know its not very clean code but maybe someone clean it. i dont have much time.

Code: Select all--pin names coming from esp8266 sdk, not nodemcu sory about that
resetPin=4
scePin=5
dcPin=12
sdinPin=13
sclkPin=14
--now setup time
pcd8544.init(resetPin,scePin,dcPin,sdinPin,sclkPin)
--now we can write womething
--usage pcd8544.print(x,line,'pcd8544LCD')
-- we have 6 line and 12 char for every line.

pcd8544.print(0,0,'-pcd8544LCD-')

i will share source as soon as possible. (now i cant register lua module so i used LUA_USE_MODULES_WS2812 module files )

PCD8544 binary file added.

Hi there

Firstly... Thank you for all your hard work and effort with the ESP's

I am trying to setup the Nokia 5110 display. Using ESP-07

I have downloaded nodemcu-pcd8544 from this post and flashed the bins to 0x00000 and 0x10000.
0x7c000 was left at INTERNAL://DEFAULT
0x7e000 was left at INTERNAL://BLANK

Flashing was completed with green icon....

I connected my display and changed the pins in pcd8544Test.lua.
Upload the file - using LuaLoader 0.86
Dofile
But no activity on the display.

I removed the display and connected LEDs to the control lines (rst,ce, dc,clk)
Dofile again.

NO ACTIVITY was observed on either of the pins.

My question:
1. Did I flash the correct bin file (0x00000 and 0x10000) to the ESP?
2. Should 0x7c000 and 0x7e000 be from Default location?

All help will be appreciated.
Thanks to all!

you dont need step 2 (at least for me)
which pins you are using?
