hi guys, is it possible to overwrite the values for SDA and SCL loaded from pins_arduino.h in my sketch?
or at least create a variant of board that doesn t get removed on the next update to the esp8266 package?
the reason being i need a variant for the esp01 with 0,2 as scl sda and so Wire.begin() works
i don t want to use wire.begin(0,2) because it s called in the adafruit lib, not in my code
@tzapu another option would be to modify the begin(void) to check to see if begin(sda,scl) was already called and not reset the pins. This way, in your sketch setup you could call Wire.being(sda, scl) before init the adafruit library.
anyone noticed is device wake up from deep sleep early ? If i make it sleep for 5 minutes, sometimes it just wakes up after 2 mins
call it before your library calls begin
like some pin that can wake it up to be floating or something
did you tie them together? how does that work? I have not really used that function yet...
i'm not sure how the WDT detects the time has come in means of code, but I imagine it reads and compares the clock, or has an alarm, so in case of an overflow it might not be made to handle that condition
rst to ground should keep the mcu off, should it not?
nope, rst should be grounded when in use
it's active on high
nice board btw
right, they are tied together and pulled up by a 2.2k resistor
thanks
perfect little temperature node :P
plan on changing the DHT22 for an sht20 tho
not the millis(), but the actual timer value
I would also really like to know how long you live on a battery
no need for a regulator :D
this is the kind of battery that was needed
my RC transmitter is using such battery
98% of the time, constant 3.3 on a cell
then death
that's why i wanted the readvdd33 function
xD
i also should say that I run the esp on a lipo and had no issues so far
ain't lipo 4.2v fully charged and absolute voltage of the chip 3.6v ?
well the adc compares with the vcc, don't think it's meant for that
maybe to read the voltage before an LDO
because i tested it and value does not change with vcc
lipo is 4.2 yes
analogRead(17) 3.96484375; // That's (4.065/1024)1000 (Calibrated value)
do not fry yours
I killed one because i was testing with a power supply and changed the voltage instead of the max current xD
seems like they don't like 30V
I want an esp-06 with RST pin exposed
or with rst and gpio16 pin already pulled up together
that would be so much awesomeness
it's unclear to me why none of the modules have the needed pullups installed
en and rst should always be pulled up
people should be able to boot without resistors
i.e. arduino shut the chip down
@Links2004 you switched the flash chip to another on your device ?
