Re: SCT-013 values

Hey Guys, I hooked up four SCT-013 (-030 / 30A) with a CD4051BE to the ESP8266 (NodeMCU). The CD4051BE is only to expand the amount of analogue interfaces. I hooked it up to the 4 groups in my fusebox but I think I'm getting crap readings. Anyone any idea? You can find the values here: https://thin...

Re: WiPy 2/ESP32 specs and performance

On the device side I'm actually using Microchip RN2483 Lora modules in a tracker and dev boards connected to a PIC32 MCU (not yet running MicroPython). RN2483 is certified by the LoRa Alliance and well documented so you do not have to bother too much on the LoRa stack implementation. Yes, I know it...

Re: WiPy 2/ESP32 specs and performance

Well, I hoped to use the board in a reasonable time frame for LoRa projects, but it seems to far away. I didn't expect a matured product but the current status was a surprise. It was too early to ship product in this stage. Board itself looks OK, but in lack of circiut diagram and detailed hw info ...

Re: WiPy 2/ESP32 specs and performance

In fact current LoPy/WiPy2 firmware is in alpha stage, even I do not cosider it being a beta release :( For example there is an old floating point bug which has nothing to do with the chip vendor but the way how MicroPython ported. Same is for the documentation, LoRa stack is not documented, there ...

Re: Downloading 1GB of data with MicroPython ESP8266 port

I wonder how all the Linux applications running on laptops and smartphones get away with not doing that. Perhaps those sockets are somehow different? They're different in that they have a full socket.setsockopt implementation that supports SO_RECVTIMEOUT and they're running under a pre-emptive mult...

Re: WiPy 2/ESP32 specs and performance

Some WiPy 2 specs and performance that it would be useful to know, theoretically and measured : - free RAM (depends on firmware version); - flash memory available for MicroPython user; - WiFi speed and range in real user cases; - Bluetooth speed and range in real user cases. You realise the ESP32-I...

Re: Code-breaking

MicroPython has now been ported to multiple platforms and there's an ongoing effort to develop a unified model for hardware such as UARTs, pins and other interfaces. Some breakages are inevitable in modules aiming to support this model. Absolutely. Except that this change doesn't address such issue...

Re: New semantics of utime.ticks_diff

As for argument order this debate has been going on at least since the days of CP/M86 vs MSDOS 1.0, and probably since the time of Babbage ;) I'm agnostic on the subject; it's all down to age. If you're young, you remember. When you get to my age you have to look it up every time :? Personally I'm ...

Re: 433 Mhz / FS1000A libary fo micropython?

Hey guys i'm trying to connect my esp8266-01 with a FS1000A to a electrical socket like this: http://www.conrad.com/ce/en/product/526915/RSL-Wireless-switch-Adapter-1-channel-Switching-capacity-max-2000-W-Max-range-open-field-30-m?ref=list There are no real protocol standards for these 433 devices ...
