This I was referring toMy LDR based DCG3 preamp build is coming along nicely. Excellent LDR kit with psu and OLED provided by zdr.
I just take any four from the batch and calibration does the rest. That's the beauty of this design.I'm probably using nonsense words, I just mean the one that stands out
Yea I know.. its probably not very beneficial to match them well up front, however it can hardly be a disadvantage. And there must be some limit to the precision of the calibration factors? Someone mentioned the sorted S-version, which was my plan until I found out they were around double the price of what I got now (with my availability). I try to do everything optimal the first time, otherwise I'll just later wonder "Maybe/What if.." etc. and end up buying stuff several times just to remove this small doubt.
Anyway you're probably right

Very nice!!!
Next step is to try 256x64 oled
3.12" SSD1322 OLED
Here is how it looks at a diy preamp from a friend of mine

Not that it cannot be done, it's just that this project does not have any spare pins left for anything wider than i2c. One could add another Arduino just for display control, but I don't think it's worth it.
It will be very interesting also 20x4 oled

Looks good, but kinda pricey. Not that this project does not deserve it though.
Would you think that something like this will work?

i have latest AIO board with 2004 lcd.
i want 4 lines at the welcome screen but only 2 appears.
the code is this:
// Specify the LCD number of rows
// Only 20x4 and 16x2 are supported
#define LCDROWS 4
#define LCDCOLUMNS 20
// Character to be used as a cursor
#define CURSORCHAR 255 //42
// If you need a delayed relay contact (for tube filament preheating, for example), uncomment the following #define line.
//#define DELAY 30 //** The value represents the delay in seconds. Maximum 100. Connects PIN_EXT_R6 to GND after DELAY seconds.
/******* Text messages *******/
char msgWelcome1[] = "Test"; //** <-- maximum 20 characters (line 1)
char msgWelcome2[] = "Test"; //** <-- maximum 20 characters (line 2)
char msgWelcome3[] = "Test"; //** <-- maximum 20 characters (line 3)
char msgWelcome4[] = "Test"; //** <-- maximum 20 characters (line 4)
what i have done wrong?
