Re: BME280 with SPI?

Hi,

Actually I run all sensors over I2C and they are all working.

Re: Deep Sleep or other power saving functions?

@ESP_igrr Does the changes according to the Hardware Design Guidelines on CHIP EN
with the R10k and C100n apply to the WROOM32 too or I have to implement this separatelly
ie outside of the wroom32 module?

Re: Deep Sleep or other power saving functions?

I'm using the Rocket 32-Rev1 (silicon rev. 0)

It's strange You need some mods on the sparkfun board.
They claim 2.5µA current in deep sleep for this board.

Re: Deep Sleep or other power saving functions?

@kostyan5 which board exactly are You using?

AFAIK there is no difference if You pull up that pin to high.
My board needs ~90µA with ULDO and Li Ion charger hooked up.

Re: Analog READ - Precision?

Can anybody from espressif please make a statement on this problem? Basically I don't need to measure Voltages lower than 0.15v but I would like to be sure about what is going on there. @ukonline2000 Currently I correct the measured values by software and it works pretty well so far. I didnt made te...

Deep Sleep or other power saving functions?

Hello,

Are there any working power saving functions right now?
For silicon Rev 0 or 1.

Does somebody have got some measured data (with setup)?

Analog READ - Precision?

Hello,

Is there a solution for Analog READ (silicon revision 0) allready?
I'm reading 1438-1440 for 1,32V (@3.33V Supply).

No matter if floating or with pulldown, the readings are allways the same.
Basically accurate with a shift of -0.15V

Regards,
Rick
