Does anyone know where there is a *SIMPLE* guide to using these things - that doesn't even mention he word "Arduino"? No, I'm not going to give in, buy one and spend a year learning an obscure C dialect, I'd rather just forget the ESP-01 than consider that. I don't want to build a programmer on breadboard - I have one with a switch. (Of course, it came with no instructions whatsoever). The info on updating the firmware seems to be written in Hebrew and never seems to go step-by-step. The documentation was written for people with a PhD in designing computer chips while riding a unicycle. More seriously, the display in the latest version of the programming software isn't like the display shown in the instructions. I managed to get the thing to read the data off the ESP (after changing the SPI speed from 40MHz to twenty-something - no-one warned me that this might happen). I have the zip of the latest AT system, but finding out how to install it is a nightmare. I have the instructions that tell you to put certain files in certain places (but not how to do it) but it shows extra files in the list that aren't in the package that I have. Figuring out which bits are needed for a 4 Mbit module is a pain anyway. I obviously need a 10yr old Arduino "coder" who could sort this c**p out in 10 mins... :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

There's this thread with successful flashing: Updating ESP-01 AT firmware And this one: Flashing the ESP-01 PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |

Hi, For anyone looking for more info on the ESP (ESP8266 and ESP32) checkout Random Nerd Tutorials at https://randomnerdtutorials.com/ and Simple Projects at https://simple-circuit.com/ I have found these sites excellent. Don |

Thanks, Don, but nothing that uses an Arduino or the Arduino IDE is of any use to me, I don't think. I'm no fan of them at all - or the C language in any of its variations. As I don't have an ESP32 that stuff isn't of much interest to me either. Thanks anyway, I'm sure your links will be of help to someone. :) I did once play with an Arduino but their IDE is too big (over 500MB) and simply isn't practical on my little fanless PC. It's fast enough, but storage on C:\ is restricted (less than 60GB in total) and I can't justify it. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

Can someone please tell me what the practical use is to combine any Mite with an separate ESP-Module? I also have not done anyhing with any ESP or Arduino Stuff myself yet for generally not being such a fan of WiFi or C (though basically understanding it).  Andre ... such a GURU? | ||||
| Mixtel90 Guru Joined: 05/10/2019 Location: United KingdomPosts: 7938 |
Yes. :) If you have, say, a 'mite with an ESP-01 and a touch LCD display you can use it as a controller. Link it to the local wi-fi. Elsewhre, have another 'mite with an ESP-01 and, as long as it's on the same network, that one could be controlled by te first. Or you could just have a little board with an ESP-01 and some sensors. Leave it to monitor a fish tank via your phone and send an alarm if the PH goes out or the temp drops. Alternatively, use the connection to the network to connect to internet time or weather servers. Use one as a web server on your network and control it from your phone. There are lots of possible ideas.

Thanks for elaborating! Yes, but would you actually need a Mite for it or not just the ESP itself? What does it really add to the CMM2 for example? Andre ... such a GURU? | ||||

The esp-01 has 2 digital inputs, if you program it with annex rds, you could proram in basic, and use the 2 pins to connect to an I2c adc Search for Annex RDS on the web If you have the blue ESP-01 it may have only 512k memory, so you need to use the simpler esp basic, since annex requires 1 meg memory. Or use the arduino ide to program it in C. Volhout Edited 2021-09-25 06:40 by Volhout PicomiteVGA PETSCII ROBOTS |

The CMM2 can't connect to wi-fi without something like that. :) The ESP-01 is basically an interface block to connect a serial port to wi-fi. That's why it uses AT commands by default - it looks like a modem. The ESP modules are clever, but it all depends on what you want to do. They have limited I/O because they are actually microcontrollers. Linking them to something like a CMM2 opens up a lot of possibilities that they couldn't do otherwise. An ESP-01 only has 4 I/O pins and you have to be careful how you use IO2. IO1 and IO3 are usually used for the serial TX / RX. You could use I2C to expand the I/O on an ESP-01 though.

Hello to all. Sorry for the intrusion. Dear Mixtel90 you can see this guide "Guide on how to program an ESP-01 on IDE Arduino", it is in Italian but you can use Google Translator. Hello and good luck to all. Raros |

Thanks, Raros. I'm avoiding *everything* to do with Arduino though. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

You can also use Rx and Tx as digital pins, so as Mixtel90 suggests, 4 I/O pins. +1 for Annex RDS for the ESP8266 (including ESP-01) and ESP32--lots of wifi-enabled capability there. True certainly that the CMM2 offers many features unavailable on the ESP8266 and ESP32, especially the advanced graphics, but otherwise much of the pin I/O available with MMBasic is also available with Annex on the ESP. Some other uses of the ESP-01 with the CMM2: jirsoft's Napoleon Commander, frnno967's Maxiterm BBS client, html server.

Yay! Peter's instructions (lizby's first link) worked perfectly first time. :) I'd been using the latest flashing software (3.9.0) and the NonOS_AT_Bin_V1.7.4 data and couldn't get it to work. There is something strange though, the 3.9.0 software doesn't show the Size column so it couldn't be selected - I assume it was working from the read data. Maybe it wasn't. ----------------------- This looks interesting (even if it does involve Arduino!): https://www.e-tinkers.com/2020/04/a-better-way-to-use-esp-01-as-wifi-shield/ Using state machine design to interact with a ESP-01.

As many users seem to "play" now with ESP8266 and MMbasic - just a reminder There is ESPterm, a Web based VT1xx emulator, written by Ondrej in Prague in 2017 I posted the details & pointers, (which are still valid) here: ESPterm Topic He added some new features in 2018, like I/O port control via API or WEB But as Ondrej has a fulltime job now, he no longer enhances ESPterm I used it some time ago and found it rather stable and useful Everything is documented on Github & an excellent integrated help (Also on ESPterm Github Demo Page) ESPterm Help Demo/Docu |
