Hi, thanks for the info.
IPS is still a tft technology and has some benefits & disadvantages over regular tft.
One being price, IPS being more expensive. What is the bet most screens on Aliexpress having IPS in the title are regular tft?
Read all about it here...
Hi, looking good so far :o)
Aliexpress is normally ok, but one does have to check the quality of the items. Some are worthless junk, but there are also great bargains and prices for the same item, if bought locally, are often much cheaper. Was even better before the tax man cottoned on. We now...
Hi, I have put a new file for you on github. In the firmware folder, there is a folder called bm282
use the firmware.bin file in this folder, to replace the original and re-flash your esp32.
Please post some photos of the screen to show if the colour has changed.
HI, alas you tft is faulty.
I have had reports of two 3.5" tft screens showing a white background (one on a shutter tester and one on my weather station) but have never had a report of it on a 4" screen.
If there is a way to correct this within firmware, I do not know, will look into it.

Hi, just the rotary encoder and blue button connected will get you going.
Output can be viewed on the pc screen (using Arduino Serial monitor, or any comms terminal program) so even if the tft is mis-wired or having issues, one can see ifthe esp32 is working ok.
Although, please try not to...
Hi, yes that is perfect.
It will undoubtedly be the 2102 USB driver. Even if it is not, it is no great issue. Windows Device Manager will show which driver it is & if your computer has it loaded.
Hi, I have never thought about build plate sizes.
Designed it using my machne & that is about all I can do.
Different manufactures & machines will have different tollerances and quirks.
Mine, for example will always print holes smaller than drawn. I would have thought the post-processor...
Hi, when you look at the sensors, not only do they have the lens that protrudes, but also a rectangular protrusion.
It is the rectangular protrusion that stops the lens fitting in a hole. Otherwise, the pcb could have the holes drilled for the lens to look through. The sensor could then be...
Hi, should be no issue in extending the sensor leads, however the decoupling capacitor should be as close to the sensor as possible.
There should be enough room on the existing strip-board to fit everything.
A bespoke pcb would be the ideal, but the issue remains how to align five sensors...
Hi, the light sensor does not do much. Most people do not add this, or the LED matrix.
The sensor just shows the ambient light level. It does not interface with The Shutter Tester in any other way.
Hi BM,
Yes, you could have all 5 Lasers on, wired to 5V. This is how my 3d printed Laser box is wired.
I have never got as far as adding the additional two sensors for vertical shutters within the 3d printed box.
This is something I will/may get round to. Two issues, firstly, there is very...
Firmware Update
Latest firmware 4.1.0.5 for ESP32 is now on Github.
Oscilloscope screen added.
Sound added. (high pitch beep on completed test, lower pitch on failed test & beep when ready for next test)
Data logging appends, rather than deleting old file (option to delete old files at start...
