- ESP-PROG is a development and debugging tool launched by Espressif, which has functions such as automatic firmware download, serial communication, and JTAG online debugging. For specific usage instructions, see: ESP-Prog Download and Debug Board Introduction . ESP-Prog uses FTDI's FT2232HL as the USB Bridge Controller chip, which can be configured to convert the USB 2.0 interface into serial and parallel interfaces that support multiple industry standards. ESP-Prog uses the default dual asynchronous serial interface mode of FT2232HL , and users need to install the corresponding FT2232HL driver on the computer to use it.
Note: The computer will recognize two ports,
端口序号大的是 Program 接口, and the one with the smaller serial number is the JTAG interface. Please refer to the " ESP-Prog Download and Debug Board Introduction " instructions. Before connecting the ESP-PROG tool, it is recommended to close any security protection software on the computer.
- The ESP-PROG tool Program interface can establish a connection with the ESP32-S3-WROOM-1 series single module to download the firmware. The wiring method is suggested as follows:
| ESP-Prog | ESP32-S3-WROOM-1 |
|---|---|
| ESP_EN | IN |
| VDD_3V3 | 3v3 |
| GND | GND |
| TXD0 | TXD0 |
| RXD0 | RXD0 |
| GND | 100 |
At the same time, make sure that the and Strapping pins of the ESP32-S3-WROOM-1
GPIO45moduleGPIO46are floating or low when powered on.
- If you are using the ESP32-S3-WROOM-1 series of modules, it is more convenient to use the " burning board " of the module to burn the firmware. ESP32-S3-WROOM-1 series modules and ESP32-WROOM series are pin to pin, ESP32-WROOM can use the programming base and programming fixture, ESP32-S3-WROOM-1 series modules can also be used . Please refer to here . The programming boards available for ESP32-S3-WROOM-1
ESP32-DevKitSseries modules are ;
- In the stage of burning firmware for mass production of modules, a one-to-four " burning fixture " is also provided to download firmware efficiently. The programming fixtures available for ESP32-S3-WROOM-1 series modules are:
ESP32-WROOM-V1
- Use the " Flash download tool " released by Espressif to directly burn the project firmware (bin file). For instructions on using the " Flash Download Tool ", please refer to:
