GPIOs do LoRaMesh da Radioenge: Portas digitais

Aprenda como usar as GPIOs do módulo LoRaMesh da Radioenge

As GPIOs do LoRaMesh da Radioenge possibilita que possamos fazer aplicações de automação com um uso reduzido de hardware, dedicando apenas ao circuito de chaveamento (se necessário) e de alimentação. No total temos no LoRaMesh 8 GPIOs sendo todas configuráveis como entrada ou saída digital e duas como leitura analógica. Porém neste post vamos apenas abordar as portas digitais. Por qual motivo…

Ive been thinking about a generic public services architecture for PierMesh. A BBS, a digital library, an event calendar/registration system and a small publishing platform for media. I think these would be easy to make distributed/widely accessible through both typical technologies and LoRa/Halow. It should be technically simple so almost any device can access it and I think you could run a read only/text only site along with a more robust version easily. I think this might be where I focus for the one box mesh deployment idea. It's very much in line with the idea of disaster preparedness that's part of why I'm so into PierMesh.

Like, the problem with making this coms library is that it is inherently integration testing at almost every step. I'm doing a mesh-of-meshes communications library that translate between espnow, ble, and LoRa, every step from the routing to the transmitting is multi device testing. It has made building this out a nightmare because every debug step was like, plug in device, flash device, remove device, plug in device, flash device, plug first device into power, run tests, oh, that didn't report correctly, okay, which device was the issue... Esp32-s3's technically are capable of usb-debugging, but also they're annoying as hell about it. This makes my life way better.

My worker firmware works! It flashed itself over, now just to add some roll back, security, and validation features. But effectively this means I never have to plug in another ESP32 to send them firmware. I can just tell them to post to MQTT from the worker firmware for logging and post the firmware binary to my local file server. This makes my life so much easier while building out this mesh of meshes multi-protocol com lib. Hell yeahhh

Leitura analógica do LoRaMesh da Radioenge

Aprenda como usar a leitura analógica com o módulo LoRaMesh da Radioenge

A leitura analógica com o LoRaMesh possibilita com que possamos fazer um amplo sistema de sensoriamento remoto sem precisar necessariamente de microcontrolador adicional na parte do slave. Por qual motivo usar a leitura analógica do LoRaMesh da Radioenge? Uma leitura digital em muito dos casos já é mais que o suficiente para saber se algo está ou não funcionando, mas a leitura analógica do…
