Dadzilla74 Posted September 15, 2019 Posted September 15, 2019 Hi Guys, Anyone up for a challenge? I have set up a Duinotech 164x64 Display (https://www.jaycar.com.au/arduino-compatible-128x64-dot-matrix-lcd-display-module/p/XC4617 using the u8g2 library to display a menu from another program (DCSBIOS Library). The issue is that sometime the menu (void onUfcOptionDisplay1Change) item will be selected and a ":" (void onUfcOptionCueing1Change) will be placed before the menu item. For example; abcdefg (not selected) : abcdefg (selected). Each of the voids run fine without the other but placing them together (as per below) I get the rest of the screen blanking out when there is a selection. I understand that this is from the ClearBuffer and nextPage commands. Yet, I hope someone can think of a workaround to keep the menu item on the screen while the selector changes. #define DCSBIOS_IRQ_SERIAL #include "DcsBios.h" #include "U8glib.h" #include <Arduino.h> #include <U8g2lib.h> #ifdef U8X8_HAVE_HW_SPI #include <SPI.h> #endif #ifdef U8X8_HAVE_HW_I2C #include <Wire.h> #endif U8G2_ST7920_128X64_F_SW_SPI u8g2(U8G2_R3, /* clock=*/ 18, /* data=*/ 16, /* CS=*/ 17, /* reset=*/ 13); // Feather HUZZAH ESP8266, E=clock=14, RW=data=13, RS=CS void onUfcOptionCueing1Change(char* newValue) { u8g2.setCursor(0,0); u8g2.setFont(u8g2_font_samim_16_t_all);//u8g2.setFont(u8g_font_5x7); u8g2.clearBuffer(); u8g2.drawStr(15, 25, newValue); } DcsBios::StringBuffer<1> ufcOptionCueing1Buffer(0x5420, onUfcOptionCueing1Change); void onUfcOptionDisplay1Change(char*newValue) { u8g2.setCursor(0,0); u8g2.setFont(u8g2_font_crox3cb_tr);//u8g2.setFont(u8g_font_5x7); u8g2.clearBuffer(); u8g2.drawStr(5, 15, newValue); } DcsBios::StringBuffer<4> ufcOptionDisplay1Buffer(0x542a, onUfcOptionDisplay1Change); void setup() { u8g2.begin(); u8g2.clear(); DcsBios::setup(); } void loop() { onUfcOptionCueing1Change; onUfcOptionDisplay1Change; u8g2.nextPage(); // transfer internal memory to the display DcsBios::loop(); Thanks in advance for any help/comments.
