@copilot como conectar el puerto usb tipo C con el ESP32-WROOM

El conector USB Tipo C, en su diseño, tiene varios pines que pueden ser conectados, incluyendo VBUS, GND, CC1, CC2, D+ (Data plus) y D- (Data minus). Sin embargo, el ESP32 no es nativamente USB, por lo tanto, no tiene nada que se pueda comunicar directamente con los pines de datos D+ y D-. Sin embargo, puede usar el pin VBUS para suministrar energía al ESP32 y el pin GND para establecer un terreno común.
De su esquema, puedo ver que su proyecto ya incluye un convertidor CH340E (IC1), un controlador USB a UART que puede ayudarlo a comunicarse con ESP32. Puede conectar así:
  1. Conecte los pines UD+ y UD- del CH340E a D+ y D- del conector USB Tipo C (J1), respectivamente. Ya tenemos las siguientes conexiones de su netlist:
    • J1:(D+) -> IC1:(UD+)
    • J1:(D-) -> IC1:(UD-)
  2. Conecte el pin RXD0/IO3 del ESP32-WROOM-32 (U1) al pin TX del CH340E (IC1) y haga lo mismo con el pin TXD0/IO1 del ESP32-WROOM-32 y el pin RX del CH340E.
  3. Conecte VBUS del conector USB Tipo C (J1) al pin VCC del Spartan 7 - estos se usan para suministrar energía.
  4. Conecte GND del conector USB Tipo C (J1) al pin GND del Spartan 7 - estos se usan para proporcionar un terreno común.
Si falta alguna conexión en su esquema, por favor actualice su esquema y permítanos revisarlo nuevamente.

Assuming that you are seeking an interface between ESP32 (designator U1) and the CH340E USB-to-serial converter (designator IC1) via UART, here's how to wire them:
  1. Connect TX (transmit) to RX (receive):
    • ESP32 U1:TXD0/IO1 to IC1:RX
  2. Connect RX (receive) to TX (transmit):
    • ESP32 U1:RXD0/IO3 to IC1:TX
Please note that the TX of one device goes to the RX of the other device and vice versa.
Ensure both devices share a common ground:
  • Connect ESP32 U1:GND to IC1:GND
Do note that:
  • TX and RX refer to transmission and reception respectively from the perspective of the device.
  • If required, additional flow control signals (such as RTS, CTS) could be connected but aren't necessary for basic operation.
