You can see how it works HERE :
I want to send thanks to Jean-Pierre for his work, and to Itead Studio members forum, especially to Patrick Martin who have benevolence to help everyone...
Wiring :
From ESP8266 to VS1053 (5 v)
ADC : gound if control panel not used
CH_PD : to 3.3v
GPIO16: led output
TXD to Nextion RXD pin
RXD to Nextion TXD pin
D1: GPIO05 to VS1053 XDCS
D2: GPIO04 to VS1053 DREQ
D3: GPIO00 to VS1053 XRST
D5: GPIO14 to VS1053 SCK
D6: GPIO12 to VS1053 MISO (or SI)
D7: GPIO13 to VS1053 MOSI (or SO)
D8: GPIO15 to VS1053 XCS
GPIO02: free
RESET: free
I already build the Karadio32. What do I have to change to the software to integrate the Nextion Display? In your download Files there is only the HMI File. Is there no change to the source code necessary, which will be flashed to the ESP32?
