I'm afraid I am not skilled enough to diagnose your problems. What I can tell you is that I had loads of problems creating the system to build MicroPython, but all of them were solved by re-reading the instructions, each time more carefully . I wish I had read them incredibly carefully the first tim...

@mattyt So, I built MP with the changes as debugged by @clone and of course, it works perfectly. Thank you both! I'm guessing that this is a silly question, but why can't esp32.enable_ulp_wakeup() take a Boolean to enable and disable the use of the ULP WAKE instruction? It would seem good to be able...

@clone Welcome to the party! Or should I say, thank goodness, the cavalry have arrived! I have spent three days getting to the point where I can build Micropython, so that I could test Mattyt's code, but I have finally just done it. Many traps for the unwary/uninitiated... So, I will also test the c...

Those are fairly specific conditions so I think v0 and v1 chips should work ok. Yes, I think I just got there yesterday, empirically, when I bit the bullet and installed the whole ESP-IDF thing and worked through an example to use the WAKE instruction (with the ADC as it happens) and it all works j...

Well, they may sell a lot of them, but it's not because of their responsive customer service department as I have not had any reply to my query, so I guess I will just have to buy one and find out...

Yes, thanks for the pointer @pythoncoder, good call! I was surprised that it is not even that expensive, though shipping might be pricey, but I need to get this done. I hope to eventually build my own boards so I'll be able to source the right chips for those. I've mailed Mouser to find out what rev...

@mattyt Oh dear, I've looked at the code you referred to and it's fairly much mumbo-jumbo to me :cry: I guess we need to add another bool called wake to the typedef for machine_rtc_config and also another static object similar to esp32_wake_on_touch called esp32_wake but I don't see where these conn...

Yes, ets Jun 8 2016 00:22:57 is what I have on my Rev 1 boards. I agree that it would seem unlikely that they would issue a new chip version without there being need or desire to have a later version of the firmware. So, are these V3 chips on dev boards basically hens' teeth!? I eagerly await info. ...

Can anybody categorically tell me which revisions/versions of ESP32 chips are in circulation (i.e. likely to be used in a development board)? I think that there are Version 0, 1 and 3 out there (2 was very limited?). Please correct me if my understanding is incorrect, or even slightly shaky :lol: If...

Well, as I understand it, the simplest way to check is to load an Arduino sketch to the ESP32. This is what I saw (I highlighted the crucial line in italics): Global variables use 15388 bytes (4%) of dynamic memory, leaving 312292 bytes for local variables. Maximum is 327680 bytes. esptool.py v2.6 S...
