Re: Soft Watchdog
Peter, Thanks so much for taking the time to respond in such detail. I've been using PIC micros for probably 20 years now, and still use them for anything that needs 100% reliability, low resources and little or no connectivity, other than via Serial etc, they simply never crash, but they don't have...

Re: WDT - TypeError: function does not take keyword arguments
OK, understand that no software watchdog is foolproof, but can this be made more 'robust' ?? lib/wdog.py import machine as mc class WDOG(): def __init__(self): self.timer = mc.Timer(-1) self.fed = False def feed(self): self.fed = True def trig(self): mc.reset() def wdtcb(self,tmr): if not self.fed: ...

Re: WDT - TypeError: function does not take keyword arguments
Need to pick this thread up again, desperately need a solution on the esp8266 which will prevent a situation with a headless, un-manned battery powered device that needs to be able to reboot itself if it crashes. So it appears that if you disable irq, 10 seconds later the device will reset: import m...

Re: MicroPython on ESP32 with SPIRAM support
Nice, I like the nvs functionality, integers work but strings seem to have a problem: >>> import machine as mc >>> mc.nvs_setint('lastval',1000) #reboot >>> mc.nvs_getint('lastval') 1000 So I thought that I could save a JSON string, and tried to extend this but it crashed, maybe it didn't like the s...

Re: Using the ESP with a Ethernet Port through SPI
I have received these ethernet boards, what would it take to make it work on an ESP32, would that be easier ?

Since upgrading, there's no icon or text in the thread edit buttons ?

Re: MicroPython on ESP-WROVER with 4MB of psRAM
I have my own build bash scripts and logical folder structure for the esp8266, esp32 and wipy and have now included the lobo version. But I need a couple of things: 1. Currently I have a script to generate symbolic links to the modules folder, but how do I add my own frozen modules in lobo ? 2. What...

Re: Using the ESP with a Ethernet Port through SPI
I ordered 10 of them from aliexpress, they were shipped yesterday, I am really hoping that this will work on the 8266 and ESP32 as I have a couple of things that need ethernet connectivity rather than wifi ?!

Re: ESP32 Thing Flash Options
Answering my own post
The clue was in the error message, the offset for ESP32 is 0x1000.
