Re: esp32 with built-in camera and sd card

I've got this strange picture, when using the driver. Does anyone know what could cause this? My module seems to be the same as the one the driver author was using (judging by the picture in the repo). I'm emailing the picture as a attachment, using this uMail https://github.com/shawwwn/uMail cam.jp...

Re: esp32 with built-in camera and sd card

It seems there is one from a couple of weeks :) Just found it and I'm about to test it.

vl53l0x max distance

Hi, I'm using @deshipu driver https://bitbucket.org/thesheep/micropython-vl53l0x/src/default/ for this time of flight sensor. All working fine, except it measures always in "normal mode" where the max distance measured is 1.2m-1.3m. The datasheet https://www.st.com/resource/en/datasheet/vl53l0x.pdf ...

Re: Designing resilient IOT applications

Hi Peter and Kevin, great stuff and documentation as usual! Have you tried to make the server run on esp8266 as well?

Re: TelegaGraph

Hi, I'm trying ti get this thermal printer working but I fail to get the right codepage conversion. I think the key is converting the UTF-8 bytearray into a codepage the printer recognises. Here is a self-test printout showing the active codepage iso-8852-5 along with the charset table. codepage.jpg...

Re: Feed hardware watchdog timer while in deep sleep

Thanks, Kevin. On a second thought, any hangs would happen while esp8266 is working, not in deep sleep mode, so feeding the hardware WDT wouldn't be a problem. Am I right?

Feed hardware watchdog timer while in deep sleep

Is it possible to feed hardware watchdog timer such as STWD100 while esp8266 is in deep sleep? Depending on the particular model the WDT's maximum timeout is between 2.24ms and 142ms, but I put my esp8266 for about 30min in deep sleep. I assume you can't work with the esp8266 pins while it's in deep...

Re: How can I see Pyboard script output on Mac?

I'm using ESPlorer (java based) on my Mac, however the downside of it is that it doesn't accept Ctrl+C, so no way to force terminate scripts :) Otherwise it has a nice interface. "screen" is a good built-in option as well.
