Re: WiFiMCU LUA port with many new modules and enhancements

I just had time for some quick tests of this new binary. The readV function is very convenient. Likewise the multiple samples and standard deviation. I found it interesting that a several second loop only raised the chip temperature three degrees. I confirmed the pin 1 issue is fixed (and now that I...

Re: WiFiMCU LUA port with many new modules and enhancements

Got it. Thanks for the clarification. Speaking of tools for pushing from Linux (or Mac, I guess). For pushing text files such as Lua scripts into the WiFiMCU filesystem I've had good luck using "luatool.py", a Python program I found on esp8266.ru (thank heavens for Chrome's Russian to Engl...

Re: [EMW3165] ADC Readings

I forgot to ask what kind of frequency of averaging of ADC values are you planning, and will this be a simple running average?

Re: [EMW3165] ADC Readings

I connected a Siglent SPD3303S (precision power supply) to pins 13, 15 and 16 in turn and used adc.read(). Just as you said, the ADC function works fine. So there's a mystery with yesterday's measurements with the temp sensor, but that's my problem. But for me with your .13_LoBo bits I cannot make t...

Re: [EMW3165] ADC Readings

Aha, too many different boards and pin mappings. I feel silly. The arguments to adc.read() for WiFiMCU are of course the raw "Dn" pin numbers. So the five analog pins correspond to read() arguments of 1, 13, 15, 16, and 17. I ran some quick tests on all these pins with the same input of ab...

Re: WiFiMCU LUA port with many new modules and enhancements

Direct Linux support will be great.

But I've had no problems updating the bootloader and firmware using WiFiMCU Studio for your January 11 bits (0.9.13_LoBo) and at least one earlier version. I've had other problems with this studio program, but not with flashing binaries.

Re: [EMW3165] ADC Readings

I've confirmed odd behavior from two EMW3165 modules on WiFiMCU boards purchased last October: one running the WiFIMCU bits rev "0.9.6" and the other running Loboris' January bits rev "0.9.13_LoBo". I connected a LM35DZ temperature sensor to the first ADC line (pin "D1"...

This forum's search index

I couldn't figure out how to contact the admin to ask this question directly. If I search this forum for "Micropython" the result is a message about "Micropython" constituting "too many common words". Does this mean the search index is simply not set up, that it's confi...

Re: MICO 2.3.0.2

I'm a beginner with the EMW3165, but I've studied the STM32 platform uart code and the STM32 chip datasheet a little bit recently and I'm convinced that if the hardware flow control is being properly enabled (still picking through the config code), the mechanism would have to be the opposite of what...
