PandaPI with Anet LCD12864 does not work
In the PandaPI Facebook group I reported a problem with the control of the LCD that I use on my Anet. It concerns the display: LCD12864 BL - ST7920 - serial mode. Mark has already made a number of suggestions, but they have not led to a solution. Mark even ordered an LCD to investigate what the problem is. Great service!!!! Because Github seems like a better place for this problem, this issue was created. If not correct, please let me know. I wonder if more people recognize this problem and maybe already have a solution for it. Am really curious. The buttons and beeper both work. The LCD display shows blue light, but no information. LCD display has been tested on the Anet and works fine there. The connect LCD_RS, LCD_EN and LCD_D4 connected in different ways. Result remains the same. Does anyone know the definition of RS (Register Select/ Chip Select, D4 (Master Out Slave In/R/W) and EN (Enable/serial clock). See also the info in the Facebook group.
the display needs: . "U8glib", "U8g2", "U8g2 Adafruit"
And try this in the config: #define ANET_FULL_GRAPHICS_LCD #define ST7920_DELAY_1 DELAY_NS(125) #define ST7920_DELAY_2 DELAY_NS(125) #define ST7920_DELAY_3 DELAY_NS(125)
the display needs: . "U8glib", "U8g2", "U8g2 Adafruit"
And try this in the config: #define ANET_FULL_GRAPHICS_LCD #define ST7920_DELAY_1 DELAY_NS(125) #define ST7920_DELAY_2 DELAY_NS(125) #define ST7920_DELAY_3 DELAY_NS(125)
Thanks, but in which file can I find the definitions of "ST7920_DELAY_x"
