I also bought some of these thermometer by mistake (I did not realise about the "Lite" suffix). The LCD driver seems quite easy: the data sheet is almost the same...
I will extract the firmware but, is there any tool to disassemble it and learn how the GPIOs are configured?
I will try to open it tonight… On Tue, 25 Jan 2022 at 04:30 Victor ***@***.***> wrote: > Good photo of the board from both sides + datasheet: 'shows the...
I've found these photos from the fcc registry: https://fccid.io/2AQ3F-CGDK2/Internal-Photos/Internal-Photos-4716361.pdf
And these are the photos of my device: https://share.icloud.com/photos/09asHIA9n8xlDzkfAkIc8A6Iw https://share.icloud.com/photos/0862Rxkd4kzv-0xz32-SoHDLA I tried with an old scanner I use for documents and so on and the quality is way worse that...
I make a last photo with maximum exposure and it is easier to see the pcb lines: https://share.icloud.com/photos/06a-QTMkplOKDEDuzNtu6jVhw https://share.icloud.com/photos/063PAj_r645F3A_XFdIrlHL2A
Umm, @spiri439 said that ATC_MiThermometer worked for him but it cannot be possible: this firmware (atc1441) only supports LYWSD03MMC, which uses different SoC pin for I2C. Maybe he commented in...
Seems that this device uses a subset of CGG1 pins. So CGG1 firmware should work perfectly except for the LCD display. I think it will be better to start with...
After debugging the lambdas with X-Ray, it seems that extra time comes from: - Initialisation time:
I am still analisyng what are the main latency sources. In my setup, it is: 1. Lambda startup: ~~500ms~~
