Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I wish it was possible to port and use this $12.99 ESP32-S3-LCD-1.47 Espressif's ESP32-S3R8, a dual-core Tensilica LX7 processor clocked at up to 240 MHz wireless connectivity 512KB of RAM 8MB of PSRAM 16MB of Flash memory 1.47-inch TFT LCD screen, offering a resolution of 320×172 pixels display is driven by the ST7789 controller Edited 2024-10-08 23:29 by lew247 |

MMBasic runs on it, even has OPTION RESET RP2040-GEEK @Phenix: thanks, I though Annex was stopped. But apprently it is alive again. Volhout Edited 2024-10-09 00:37 by Volhout PicomiteVGA PETSCII ROBOTS |

Annex has never been stopped. It's a very powerful web-enabled rapid development system in BASIC, focusing now on the ESP32 series, with browser-based module flashing and browser-based code development.

That ESPNOW is pretty darned exciting; I've read round-trip latencies in like 1 or 2ms. Bummer about his terms or I'd be using it for WiFi, BT, Ethernet and ESPNOW. I'll use B4R instead which is compiled Basic syntax. |

I've just gotten 5 ESP32s talking with ESP-Now under Annex, two of them gateways talking through serial to a Raspberry Pi 4B. Pretty nifty, with supposedly better range than via UDP, and with notification of failed delivery. No commercial use, though--you're right. Not a problem for me.

I've been watching for someone who is actively using ESP-NOW and here you are, holding out on us dammit I understand that nothing WiFi can get in its way but do you think those claimed response times are for real? |

And are they the max or typical or what? (OK, the max will be forever but you know what I mean...) John |

Might be misunderstanding you John but the ESP32 and now the Pico, I guess we can assume are ubiquitous. ESP-NOW is an Espressif technology and PIO is RPI Pico. I think that committing to both of these is pretty darned safe. Not sure if we're on the same track |

Why am I excited? Well because I look, constantly for "better methods". I want to see wires go away. When one talks wireless, many think about the tranny radio that had all kinds of interference issues. And yet, overhead cranes have had wireless controls for many years. There are even wireless e-stop devices that can't be jumpered "because they're a nuisance" I'm thinking about a machine controller where the only wiring is for a 200VDC bus..period |

Harsh judgement to say I've been holding out when I only got my preliminary setup working to my satisfaction yesterday -- My needed timescale for response of an actuator is more likely to be minutes rather than milliseconds (and maybe hours of human time). I put in a test timer. The sender saves the Annex millisecond timer and sends the message with ESP-now. The receiver does a fair amount of processing to see that the message is for itself, actuates the relay, and rebuilds and posts the web page which is the alternate method of setting the relay, and then transmits a response; the sender does a bit of processing on the responding message, and prints the message and the elapsed time. I'm seeing 14-15 milliseconds. I'm sure it would be much faster in C code and optimized for response time (and no web page build). You could also send directly to a specific MAC address rather than broadcast and have each receiver determine if the message is for it. ~ Edited 2024-10-09 09:39 by lizby PicoMite, Armmite F4, SensorKits, MMBasic Hardware, Games, etc. on fruitoftheshed |
