Re: IO0 / EN minimum/maximulm timing

Hello, yes i’ve ckecked it. Maybe C18 is not the good value (RC circuit on EN). R = 10k and C = 0.1uF. There are the value proposed in the espressif DevKitC schematic. GPIO2 is floating. I’ve red on the espressif Github that a value of 1uF is recommanded for C, maybe my problem is on this value. Any...

Re: Have to Press "EN" To Start Custom Board

Hello, I have exactly the same problem with my custom board. All features are ok, but the board doesn’t start without a press on the EN Button. I’ve started a topic on this problem on june with my schematic and I’ve checked all the pins. Any help will be appreciated. The link on my initial post is :...

IO0 / EN minimum/maximulm timing

Hello, I have developed a board based on ESP-WROOM-32, whose objective is to be inserted in a box to measure the control surface deflection for RC planes and gliders. The system works with two boxes connected by Wifi (one of the boxes being AP and the other station) and a web app embedded in the AP ...

Re: CMakeList build system question

Hello,

Thank you very much ESP_Angus, it was the problem.
It's very curious because it works under windows (${PROJECT_DIR}, but not under Linux. Maybe under windows PROJECT_DIR is set in the PATH, i will check.

Problem solved :P

Regards.

ESP-WROOM with MPU6050 design

Hello, I have developed a design with an ESP-WROOM-32 and a MPU6050 products and I attached the schematic in the attachment ESP_MAD_RevE.pdf . The design is based on the esp32 adafruit feather schematic, with the introduction of one SPDT switch to power on/off the board and the interface with an MPU...

Re: Tiao Jtag adapter (tumpa) pb

Hello, I was probably a little bit tired. In fact I was a problem of wiring between my tumpa and my ESP32 board. All is working properly now and effectively the installation of the D2xx ftdi driver is not mandatory under linux (i'm working on ubuntu 18.04 LTS). ftdi_sio & usbserial drivers are worki...
