NES emulator on an ESP32

[ESP_krzychb]

Hi a2retro,
To fix back-light check http://www.esp32.com/viewtopic.php?f=17&t=325#p3823 by rudi.

Okay so I looked more closely at the change documented by Rudi above and the back-light works as expected.
I looked at that last night but it was late - that's my story ...

[a2retro]

Seems like I make one step forward and then step back again.
After updated esp-idf to the latest code i get this message

$ make flash
make[1]: *** No rule to make target 'libcoap/src/address.o', needed by 'libcoap.a'. Stop.
make: *** [/home/Glenn/src/esp-idf/make/project.mk:378: coap-build] Error 2

my libcoap dir is empty

i see it's a submodule - not sure why it's not being pulled in

Edit: recloned with --recursive worked as well. It seemed odd as initially I saw other submodules automatically pulled down but not libcoap for some reason

@a2retro,
Try this one:

hi guys,
what you think?
can we save ROMS to sd card (yes )
make a menue for selecting from this ( yes )
after select, ROM cpy to nmap (yes )
is no sdcard found, load "factory" 0x10000
return romdata (yes)

perhaps we can nmap sdcard (raw) too (usually yes) vfat?

best wishes

Unfortunately, we can't mmap SD cards like we can mmap SPI flash. Flash MMU only knows how to use SPI0 peripheral to talk to SPI flash chips. But copying from SD into flash and mmap-ing the flash is certainly doable.

yes , first steps now it works from sdhc now too, txs ivan.
play with a menu just in time for simple selection and load the next game

hi

cause tested with ESP32 WROVER KIT V2 ( black )
found out, that we must change a small thing.

https://github.com/espressif/esp32-nese ... _lcd.c#L53

Code: Select all

/*orig WROVER KIT 1 ( red ) Backlight active high! */
// #define LCD_BKG_ON()    GPIO.out_w1ts = (1 << PIN_NUM_BCKL) // Backlight ON
// #define LCD_BKG_OFF()   GPIO.out_w1tc = (1 << PIN_NUM_BCKL) //Backlight OFF

/*rudi mod 06 jan 2017 on WROVER KIT V2 ( black ) Backlight active low! */
#define LCD_BKG_OFF()    GPIO.out_w1ts = (1 << PIN_NUM_BCKL) // Backlight OFF
#define LCD_BKG_ON()     GPIO.out_w1tc = (1 << PIN_NUM_BCKL) //Backlight ON

txs for your great work Jeroen!
now i need a PS1/PS2 Controller
i usually do not play so sorry for this i have not PS1/PS2 controller here
