Re: A better ESP-32 multasking example

which route of software installation ? i've got both the idf and sketchbook/hardware routes to compile, link and flash. relatively painlessly as well. i was actually thinking about asking for a zip from anyone with a working arduino, ~/sketchbook/hardware esp32 install. i'm also thinking that the pe...

managing width

and now of course this probably should be in off-topic, not a stm32 in sight i once tried describing this in ascii, however as they say :- 2018-02-11 19.49.24.jpg 2018-02-11 19.49.45.jpg note the power rails it also explains why i buy breadboards in 4's or 5's or more, they vary the spacing and size...

Re: i2c device not visible

ok, it should have gone in off topic, i'd thought not into libs & hardware, hence general :-)

it was just a bit quirky and puzzled me.
actually that's probably a reasonable description of me as well. puzzled is pretty much the norm !

Re: i2c device not visible

stephen wrote i've a few i2c 0.96" displays, pins in sequence vcc, gnd, sda, scl, all of the same type. and observing the missing resistors makes them i2c at 0x3c when nothing i2c is working, my response is to scan for i2c devices indirectly testing them one at a time. i've nver had 2 of these on th...

Re: i2c device not visible

@Roger what other i2c lib ? there ain't one ! the example code i ctl-c'd it and ctl-v'd in from a esp8266 example on the www, only has Wire.h in it - this is the esp8266 core so it's doubtful if they're also done the renaming of (Wire to HardWire ?) ? with 4k7 sip in circuit, i2c scanner 120 odd err...

Re: i2c device not visible

when i test displays it's one at a time, even on spi, but particularly so on i2c :) core it's the esp8266 official one - i did say the point i was getting at was that it worked when i removed the sip resistor pack, at least as far as the 'official' i2c scanner was concerned. not seen any snowflakes ...

i2c device not visible

i've a few i2c 0.96" displays, pins in sequence vcc, gnd, sda, scl, so thought i'd test them. i also have some sip resistor packs, 4 off 4k7 with pin 1 as the common, so it adds pullups on scl & sda :) vcc is taken from the lolin v3 esp8266 board vin pin, hence in general not libs & h/ware :) i know...

Re: how are multiple partitions handled

oh i do delight in asking illuminating questions :lol:

i don't really care in the answers, i used to ask questions in a discussion group with the intention of destroying
a platform.

i've grown a bit, ok maybe not quite enough to not enjoy the answer
