Re: Adapter PCB to use a 64x128 pixel OLED display on a Wemos D1 mini?

Apparently that one could do: It has additional provision for temperature sensors, but on must not use them.

Adapter PCB to use a 64x128 pixel OLED display on a Wemos D1 mini?

Hi, has someone already realised an adapter PCB to use a 64x128 pixel OLED display on a Wemos D1 mini? The standard 64x48 OLED shield is extremely limited. I am currently wiring the display on prototyping PCBs but I could figure it were much more convenient to have a PCB for it. Maybe it already exi...

Arduino IDE: Serial.println(__FILE__); does not show the path?

I am a bit diapointed that [Codebox]Serial.println(__FILE__); [/Codebox] does not show the complete path of the compiled sketch, like ESP32 does. Especially when you use tabs, the the current .ino file is not identical with your folder, so the information is useless. Where can I address the issue? R...

I have searched more about the techniques how to best consume streams...
Everybody has obsolete smartphones in their drawers. They are perfect to listen to radio streams.
No need to tease an ESP8266 for that.

Re: How to print the date of yesterday?

Finally I found out alone. //***Variables for Time*** tm* timeinfo; tm* yesterdaytimeinfo; time_t now; time_t yesterdaynow; static char charbuff[120]; //Char buffer for many functions //*** In program *** yesterdaynow = now - 86400; yesterdaytimeinfo = localtime(&yesterdaynow); strftime(charbuff, 30...

Re: What can be done on an ESP8266? Show your beasts...

I teach at our local library about Arduino programming and light electronic usage. Have kids from pre-teens to their 80's. :) We did a simple weather station... two sensor modules and about 2 minutes of breadboard wiring and a little code and they had a weather station with 24 to 48 hour predictive...

Re: What can be done on an ESP8266? Show your beasts...

First sorry for the late response I have been ill for a while... Interesting!!! I retired to a quiet mountain location, but the concepts do remind me of my former profession. Is 8 Hz a choice or a limitation? It is a DIN/ISO regulation requirement. Sound pressure levels have to be processed a that p...

How to print the date of yesterday?

Hi I have a program that issues at midnight the summary of the past day. It should issue the summary in a line appended to a file. That file should be in the csv format, for post processing in Excel. All is done now. But I would like to begin the line with a date identifier. Only day/month. And that...

Re: What can be done on an ESP8266? Show your beasts...

As an example of power of an ESP8266... early-on in the Covid, I thought I could help with the staggering demand of ventilators - https://inqonthat.com/inqvent/ . If I recall correctly, the little ESP8266 was able to handle reading two pressure sensors, while controlling two servos and a PWM motor ...
