Yep, that now works, thanks.

On the Pro Mini with a test text screen of circa 64 characters the software SPI takes 1954mS to write the screen and in hardware SPI mode it takes 387mS.

For the program 'HCDisplay_Hello_World.ino' for a 3.3v ATmega328P I had these settings; //Arduino Pro Mini pins #define CE_PIN 10 #define DC_PIN 7 #define CLK_PIN 13 #define DIN_PIN 11 #define RST_PIN 9 I ran it in software mode with the options.h set to #define ST7565 and used; HCDisplay.Init(DIN_P...

If you do end up trying it I’d greatly appreciate it if you could let me know if it works. On an Arduino Pro Mini example 'HCDisplay_Hello_World' works in software SPI mode with the HCMODU0245. If I comment in HCDisplay.Init(CE_PIN, DC_PIN, RST_PIN); put options.h to '#define ST7565_SPI' then I get...

Assuming you are seeing compile errors, then I think I see the problem. I'll have a look into it and push a fix as soon as I get a chance to look at it. Yep. For a ESP32 you get errors about avr/pgmspace.h and on a DUE this; error: invalid conversion from 'const FONT_INFO*' to 'FONT_INFO*' [-fpermi...

For some time I have been looking for a decent LCD dispaly that I can use for outdoor applications, I do a fair bit of messing about with LoRa. In the past I have used a transflective 20 character x 4 line LCD, but its only 4 lines, not compact, and you cannot up the character font size. I had previ...
