Re: ESP32 I²C 5V tolerance

Many years before, I did a project using rs-485 chips (sn75176). It's dirty cheap and helps me programming my Arduino (Mega 2560) from a distence about 15m-20m away. If the I²C in your project not rocks, try this one. ;)

Cheers

Re: ESP32 I²C 5V tolerance

According to ATmega328p Datasheet, you can even run you Atmel MCU as low as @1.8V.

If you do Arduino. As far as I can remember, there is also some Arduino Micro Pro running @ 3.3V. Perhaps you wanna check them out.

Cheers

Re: redirect app trace into sd card

Just don't know how to make a pull request for your Gist. i don't think there's a way to do pull requests in gist, but you can "fork" any gist and do modifications in the fork, then post the link to your forked version for others to see. Regarding stack size selection, indeed it is a not an easy pr...

Re: redirect app trace into sd card

Here you go: https://gist.github.com/igrr/82055d824cbbc521932f32217e0710b9 . This is a slightly modified sd_card example, it shows how to redirect logging messages (which come from ESP_LOG) and, optionally, stdout (which is used by 'printf') to a file on SD card. Hey ESP_Igrr, Just don't know how t...

Re: redirect app trace into sd card

Hi igrr, Thanks for the Tip. It seems like I'd try some idea just like your answers, before posting questions. To tell the truth, I always struggling if I should "RTFM" before I start to try something out. It's pretty a experience thing. Thanks again. If my implementation as you said works well, I w...
