-
Nice to see you back ! ...cheers.
-
Hahaha, Great bloopers!
-
I remember this guy! Good to see you're doing well.
-
I bought 5 of those displays on EBay. The LED segments were a greenish blue. You could actually use just one HT16K33 to drive all 8 alphanumeric characters if you have spare 14-segment LEDs, and thus the ESP32 only needs to talk to one I2C address
-
Nice to see you in action again! I think there is a quick fix for the color difference, as that board is designed to run off 5V. Just move the VCC jumper to the 5V output of the module. Make sure the VI2C line is still connected to 3.3V though, your suspicion was right - it does set the IO line voltage.
-
Thanks David. Nice to see you. I like the display, too bad about the mixed colours. Take care.
-
Woo! He's back! Hope things are going well Mr Dave!
-
Please... use search/replace for things like that ;) I might be a freak that uses a regular expression to change 2 characters on a single line but this certainly would benefit from search/replace
-
Breadboard with 6 pin columns exists? Oh well, one more item added to the never ending shopping list....
-
Don't have a clue what the content is about, but I like this man!
-
14 segments displays are quite neat, you just can't display a lot of offensive words on only 7 segments :P
-
Yay David Watts is back 👍🏻
-
really wondering why they use 2x2 segments and one half is a different colour :( I think they forgot to sort the panels and the assembled boards with mixed colours got sold cheaper on Ali
-
Who manufactured that wide protoboard with the faint writing on it? Thanks
-
I got one of these from eBay and I was also surprised that two digits were red and two were orange! There must be a story behind this, do you think they are a manufacturing mistake?
-
Welcome back.
-
welcome back !
-
He's back! 😀
-
Those two displays have quite a brightness difference between the two digits..
