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...

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...

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 ...

Hi for my project https://github.com/rin67630/Victron_VE_on_Steroids/ I have coded an UDP transmission between modules that works pretty well: The information is grouped in a single structure payload[] struct payload { //***Operating Values from Victron/SmartShunt*** float BatV; // V Battery voltag...

Very nice !
I will give it a try after the season holidays.
Have you got a version for the ESP32 too?

Well, in my case, I use the RX pin as a third GPIO (the ESP-1 is a very small breakout). Point is, I can still use TX pin to transmit serial at the same time That is the opposite. I just would want to liberate the TX pin that is not used and pulled up with 470 Ω, which draws quite a respectable qua...

What have you done with your ESP8266s that you consider being a lot of code?

Personally I am working on
https://github.com/rin67630/Victron_VE_on_Steroids
and it compiles at less than 50% resources.

I would expect it works on the ESP8266 chip, regardless of breakout board... As far as I know, it's the same chip on all the 8266 breakouts? Did you try it on the ESP-12? Would be interesting to hear if it works. I could try it on an Adafruit Huzzah 8266. That appears to liberate the TX pin for use...

You can repurpose the RX and TX pins independently: https://arduino.stackexchange.com/questions/29938/how-to-i-make-the-tx-and-rx-pins-on-an-esp-8266-01-into-gpio-pins In my project, using ESP-1 (which only exposes/breaks out GPIO0 and GPIO2), I have remapped RX (GPIO3) as an output. This allows me...

Use a Witty ESP8266 board
It has the programing part and the ESP on two separate boards, so you can use the programming circuit without having the ESP interfering with the reset sequence.
