Black screen - Help #73
|
Nice project, thanks For now i have to give up, been at this for few days and only reaches a black screen. I tried Arduino ide older version and the latest to compile. I also tried the bombjack also (thanks) - only getting to the test squares screen upon boot. For now any suggestions would be welcome - stuck. |

What output do you see on the serial console? |
|
Only see: Also my pins is verified correct and config is: #define TFT_SPICLK 40000000 // #define TFT_MAC 0x20 // some CYD need this to rotate properly and have correct colors // x and y offset of 224x288 pixels inside the 240x320 screen |

So the sketch actually runs. Is the screen really completely black or do you see the backlight breaking through at the borders? If not you have something very fundamentally wrong like the power supply and/or the backlight control pin not wired up properly. You'd see the backlight being on even if nothing else on the screen itself works. The other way round, without backlight you wouldn't even notice that the display actually works with the backlight not working |

It's the tft_bl signal which defaults to pin 13 you should take a closer look at. |

The screen is physically working - just gets black color filled on reset immediately. Removed line setCpuFrequencyMhz(240000000); As another user suggested adding this to emulation.c does solve in my case all of the compile errors: Removed and re added the rom files and then used the python script conv_win.sh Well i think cause i manually done the py scripts i missed something but using conv_win.sh it will auto skip the roms not added. Well @harbaum - thanks for the willingness to help on this project and keep going. |

If you are facing compile time errors which you fix through some hacks, then you are obviously not compiling it in the environment it was developed in and which I have tested it in. Please use esp/IDF board integration 2.0.9 which is known to work. Once that works you can try different versions etc. |

From your previous post I am not sure if it's working now. Is it? |
Yes, thanks. I got all 4 games working with sound and all. |

Getting back to "I'm a big fan of Goldstar, will try and figure out to port at least 1 of them .)" I got this working on the galaginoplus model. The question is what available tools is there to help us figuring out the roms and addresses so on? |

tft_bl (LED on screen) is not wired to a pin but soldered in permanent
Removed line setCpuFrequencyMhz(240000000);
Comment out the pinmodes on buttons (testing first)
As another user suggested adding this to emulation.c does solve in my case all of the compile errors:
extern unsigned long millis();
extern unsigned long micros();
extern void vTaskDelay( const int xTicksToDelay );
extern uint32_t ulTaskNotifyTake( int xClearCountOnExit, int xTicksToWait );
extern uint32_t esp_random(void);
Removed and re added the rom files and then used the python script conv_win.sh
Well i think cause i manually done the …
