The latest version of U8g2 includes some modifications on HW SPI side, but i will also create an issue here and do some testing with the ST7920.Oliver
Hm, strange...Because Parallel connection with u8g2 doenst seems to work with my ST7920 128x64 display I thought I'll "just" switch to SPI.Now I found out that SPI also doesnt work. I get strange artifacts in the display and can barely see the text that should be written on the display.Then I tried software SPI and that works fine, but horrible slow.Then, again, I switched back to U8Glib and everything work awesome.I've tested this with my Mega, Nano and Uno. So I dont think that the controller is the guilty one.Any ideas?I would still prefer to use the parallel mode
I just got an SSD1306 128x64 I2C Oled display today, going to spend tomorrow figuring it out. I see SPI mentioned a lot, does this library do I2C?
The parallel interface for the ST920 should be of type 6800 (RS, R/W, E) and not of 8080 type ? i've tested mi Digole 12864ZW screen with the ST920 controller and works ok with u8glib but not with u8g2 that uses a different constructor.u8glib ->U8GLIB_ST7920_128X64_4X u8g(8, 9, 10, 11, 4, 5, 6, 7, 18, 17, 16, 19);u8g2 -> U8G2_ST7920_128X64_F_8080 u8g2(U8G2_R0, 8, 9, 10, 11, 4, 5, 6, 7, /*enable=*/ 18, /*cs=*/ 16, /*dc=*/ 17, /*reset=*/ 19);
Hi.I was wondering if you would mind including Thai font to this library.Thank you.
Hi everyone. I'm building a digital tachometer plus watch plus lean angle carbed motorcycle computer. I was using u8glib with some good results. The problem was that the mega couldn't stand with interrupts so it was basically slow to make calculation. Is this library any better? As my chipset is t6963 I also sent a pm to you @olikraus about schematics for a DC DC inverter. Thank you all for any suggestion
