Hi Roger, it should work for ESP32. I'll take a look at it but in the short term can you give the following a try: Open up the SmartLCDI2C.cpp library file in a text editor located at: C:\Data\Roger_Hobby\Control_Systems\Arduino\libraries\SmartLCD\SmartLCDI2C.cpp Find the following line on line 164:...

The distance isn't great, but there are walls in the way. If it's not far then I don't think it will be an issue. I myself have tested them though a building and they still manage to maintain a decent range with the stock antennas. If I find I need to upgrade the pigtails to either stick aerials or...

Thanks for pointing this out. I'll get a note added to the first post.

Based on the schematic, it looks to me that J1 bypasses the on-board 3.3V regulator. So… If you're using a 5V power supply, J1 must be left un-jumpered. This ensures the module is powered through the 3.3V regulator output. If you're using a 3.3V power supply, J1 should be jumpered. This bypasses the...

Hi Andrew, Just about to implement some code using the new registers, I see for RLY_ON (&off) write is used, I'm sure there is a reason for this being different than writebit of the standard on/off commands. That's correct. It's because the original register sets the state of all 4 registers at the...

Ok, thanks for letting me know.

Maybe it's being caused by a power saving option on the USB ports?

I measured the voltage between the 5v Pin and the Gnd pin on the board and that was 3.4v. The 3.3V pin measured 3.0v to Gnd. I see from the diagram that there is a "fuse" between the USB input and the 5v pin, and I'm wondering now whether this has gone high resistance. You could try probing either ...

After returning to work on them after a break I found that I could not see them via USB as Serial Ports on my Win 10 PC. I found that if I pressed and held the reset button down then the devices could be seen as Serial Port but only when I held the Reset button down on the processor board. The D1 M...

would it be possible to connect two units data pins (and power) with 10M of cat5 cable and link one to the phone and the other to the camera as a Bluetooth extender. It would be using it out of spec but it may work at lower data rates. However, these are serial devices in that they only transfer a ...

Ah, I guessed PDP-11 because I know they were still used in the 90’s. A lot of interesting old computers you’ve used there. The range seems very low, but that may be due to all the metal in my workshop. Presumably it's very line-of-sight. Given I have that, what kind of range should I be seeing? It’...
