    • RE: 💬 Button size radionode with sensors swarm extension

      @Koresh said in 💬 Button size radionode with sensors swarm extension:

      Sorry, picture's quality is not too good!
      R4 ( 10Kohm) is soldered. I read about that pullup resistor that is needed to sync with atmega SCK. Any other hint on what could cause that ?
      Maybe, that was a mistake when i changed the fuse? but I didn't have problem before with these settings.

      So I'll have to be patient to use M25P40!

      @yury @koresh

      Few months ago, I've ordered some of your nodes, which work perfectly by the way, but I needed something that could speed up testing of any sensors.
      So following our conversation on Github with Yury, I've created a PCB based on your Button size node, with a field for an extension board. The aim is to have a versatile board, and extensions that could handle virtually any sensors, like NodeManager project, but for hardware 😉
      And it's also a first time experiment in the land of PCBs

      Apart 2 errors ( maybe more in the future !), it seems to be well routed, as tests been proving, but i still not tried the FOTA function.
      Errors was a badly routed button and it seems that, after the RFM chip is soldered, communication with USBasp gets bad! Is it because SCK and MISO route ( from pin headers to atmega328 ) goes through the RFM chip before atmega ?

      You were mentioning some mods in dualoptiboot in order to flash M25P40, https://forum.mysensors.org/topic/3160/ota-flash-types-for-mysensors/43.
      Would it be possible to share these ?

      And just out of curiosity, how did you manage to solder SI7021 and TSL2561 ?
      By now, it seems like a mystery for me...

    • RE: Browser-based firmware generator

      @rakeshpai Hi, I'm following this topic closely, found your project on google to see if something similar already exists. I was surprised that it does + it's based on nodejs, couldn't be more happy!
      It's really a good intention for people who wants to get started quickly and it would perfectly complete the NodeManager.

      About the method, i was thinking about something similar that dagoma did ( a 3d printer manufacturer, based on Marlin firmware --> Arduino ). They made a subdomain where you can generate a .hex files, functions of the options you have. Then they made a desktop app which lets you upload the generated file.
      That's not the most integrated and straight, but it works fine!
      Which looks like your approch you show on your demo (btw the link on your github doesn't work, http://rakeshpai.github.io/mmysensors-network-manager )

      That maybe a good start to flash an arduino with an app ? https://github.com/noopkat/avrgirl-arduino

      If you need / want help, I'm actually working on a project with nodejs and react, so 'im in the good mood 😉
