XaviIs there anyone in the room with knowledge about <a href="https://talamanca.social/tags/ESP32" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ESP32</a> microcontrollers?I am playing with a <a href="https://talamanca.social/tags/Waveshare" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Waveshare</a> development board that has an <a href="https://talamanca.social/tags/AMOLED" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#AMOLED</a> and a touchscreen, and it says it has built-in <a href="https://talamanca.social/tags/SH8601" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SH8601</a> display driver and <a href="https://talamanca.social/tags/FT3168" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FT3168</a> capacitive touch chip, using <a href="https://talamanca.social/tags/QSPI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QSPI</a> and <a href="https://talamanca.social/tags/I2C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#I2C</a> communication respectively.<a href="https://www.waveshare.com/product/arduino/boards-kits/esp32-s3-touch-amoled-1.8.htm" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://www.waveshare.com/product/arduino/boards-kits/esp32-s3-touch-amoled-1.8.htm</a>It directly works in <a href="https://talamanca.social/tags/Arduino" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Arduino</a> with <a href="https://talamanca.social/tags/C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#C</a>, but I am trying to make it work with <a href="https://talamanca.social/tags/MicroPython" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#MicroPython</a>. Before I spend effort trying to compile it with <a href="https://talamanca.social/tags/LVGL" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#LVGL</a>, I want to know if I could print a "Hello World" to the screen as is, and while my mind tells me that I need a driver, the sentence "built-in display driver using QSPI" makes me think that I could eventually use the display without code drivers, but I don't know how.I'd love to see an example, if it's possible, or to be pointed to any resources that I can read in this regard. I am complete newbie.Re-posts are appreciated.Thank in advance 😊

Daniele Verducci 🧉That should do. Using <a class="hashtag" href="https://social.ichibi.eu/tag/i2c" rel="nofollow noopener noreferrer" target="_blank">#i2c</a> to connect the <a class="hashtag" href="https://social.ichibi.eu/tag/bme280" rel="nofollow noopener noreferrer" target="_blank">#bme280</a> to the <a class="hashtag" href="https://social.ichibi.eu/tag/esp8266" rel="nofollow noopener noreferrer" target="_blank">#esp8266</a> microcontroller on the default pins. It defaults to SCL on GPIO5 and SDA on GPIO4. I checked the pinout and they are the ones labeled as D1 and D2.

Florian 'floe' EchtlerI suspect that one of the battery's <a href="https://hci.social/tags/I2C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#I2C</a> lines is still floating, but I haven't been able to find a second test point to connect to. I've even checked another undamaged tablet to confirm the wiring, and 3 out of 4 support signals are definitely connected again.Question is: does the battery usually have its own I2C bus connected to the battery controller, or is it actually the system bus? Because in the second case, I could in theory just put in another I2C bridge...? (2/2)

Wintermute_BBSA small demonstration of my I2C serial UART driver code being used by a small "server-side application" that remotely smells of BBS. "FORTH isn't for complex applications" some say.

I decided to try to run my *unmodifed* <a href="https://oldbytes.space/tags/sc16is750" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#sc16is750</a> driver code I wrote for the <a href="https://oldbytes.space/tags/Mynor" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Mynor</a> <a href="https://oldbytes.space/tags/My4TH" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#My4TH</a> <a href="https://oldbytes.space/tags/ForthDeck" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#ForthDeck</a> keeping all fingers crossed ...... and yay, it works! 🥳So now I can use the RC2014 <a href="https://oldbytes.space/tags/I2CBusMasterModule" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#I2CBusMasterModule</a> from within DX Forth and recycle most of the code I've written on another machine (the Mynor My4TH).

LeoDJAfter a lengthy bring-up debug session, I noticed the <a href="https://chaos.social/tags/SSD1303" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SSD1303</a> not quite behaving as I expected. Pin D2 (SDA_out, which "should be left open" in <a href="https://chaos.social/tags/SPI" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#SPI</a> mode) was not staying high all the time, like I had measured previously. Rather it was shifting out some kind of gibberish data. This was not compatible with my tested idea of "just putting a diode between SDA_out and SDA_in (D1)", to still allow I2C-lows through in <a href="https://chaos.social/tags/I2C" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#I2C</a> mode, but block the constant* high signal in SPI mode.* formerly believed as
