- Tue May 05, 2015 8:24 pm #16650 Excellent and clear instructions but nothing on my little display yet. I'm using the small ESP-01 with only two I/O pins so in pong.lua do I specify sda = 0 and then scl = 2?

Thanks.

NodeMCU has unfortunately a weird numbering for GPIOs. (see here: https://github.com/nodemcu/nodemcu-firm ... mcu_api_en )

3 stands for GPIO0 and 4 stands for GPIO2. In my case SDA is on GPIO2 and SCL on GPIO0

So, I now installed ESPlorer v0.2.0. The [Save&Compile All] button doesn't work at all.

I did the following step by step:
- [Format] button
- open every .lua file, which creates a separate tab for each file
- edit ntp.lua and set your SSID, password and timezone
- select every file (tab) and press button [Save to ESP] (ignore error messages like 'not enough memory')
- select every file except ntp.lua and press button [Save&Compile]
- check your saved files, in the Command tab press [List files], you should have a .lc file for each .lua file except for ntp.lua
- select the ntp.lua tab and press [Run], the pong clock should start after 2-3 seconds
- if everything works properly, rename ntp.lua to init.lua by entering file.rename("ntp.lua","init.lua") in the command field, press [Send]

I hope I didn't miss anything. Please let me know if it works for you.

A big Thank You for the detailed instructions! Very helpful for a newb like me.
Clicking the [Run] button gives an error:

- Thu Jun 04, 2015 12:55 pm #19454 Apparently you didn't save the file 'ntp.lua' to the ESP, at least id doesn't show up in the file list you submitted. Try uploading it and run it again.
