1.0 Incorporates optional FocalTech touch interface We are proud to announce that this version also has a demo for 2.7 inch epaper with touch interface. Please refer to this demos to see how to implement this: https://github.com/martinberlin/cale-idf/tree/master/main/demos There are 2 simple demos:...

If you are interested in using ESP-IDF in your next project check it out, new models added include: [*] Waveshare 12.48 with ESP32 devKitC connector (4 SPI epaper, should get an ESP32 with PSRAM update) [*] Good display 5.83 B/w and also 3 colors Size: 600 * 448 Colors: B/W/RED [*] A new very intere...

I'm also interested to know more about this. One question though, reading the manual it says: In light sleep mode, digital peripherals, most of the RAM, and CPUs are clock-gated, and supply voltage is reduced. That if I understood well is that SPI transmission stops right, but after you send the Pix...

Hey there,
This looks like an interesting topic. Sadly I don't have any Oscilloscope in my small studio so I won't be able to reproduce. But does anyone has a hint on what's going on?
Is possible to see your SPI instantiation? PINS used, program, etc.

Solved:

Found a way to fill the display buffer from a Bitmap image (8, 4 & 1 bits supported. Just if anyone wants to take a look, here is the code:

I think here there is a misunderstanding of the concepts on how to build something. It took me a while to get it right too, since I started with the Arduino framework and PlatformIO as IDE, and that's a bit a different world. IDF way as I see it is described here: Build system https://docs.espressif...

Good so let's resume this with a funny story: ESP32 - Get's a content-length of 60Kb and starts downloading Backend - I have 60K image! ESP32 - mhhh ok but I found only 11Kb!!! so I stop downloading Backend - you fool... So in this construction I got in the middle, and started to ask, why I get only...

A bit more research and partial success: https://github.com/martinberlin/cale-idf/blob/refactor/oop/main/cale.cpp I'm just trying to call the DATA event and dumping what comes using a buffer of 1024 bytes. It's working but somehow I'm not receiving the whole downloaded Buffer. So for sure I'm doing ...

I'm also interested like ungato to know more about OTG host in the S2. It's definitivaly one very interesting feature!
Please let us know some details

Hello dear forum, I'm in the process to learn IDF coming from Arduino-framework since the beginning of 2020. I've been searching for a way to do something similar to what WiFiClient does in Arduino-espressif32. What I would like to achieve: To instantiate the WiFiClient and make an HTTP request. And...
