Re: Upload code without pressing EN and Boot buttons

OK, great you have one. You do not need to press the buttons to get it into flash mode. If you do there is something wrong. There are many knock-offs out there that there is a issue with the timing on the GPIO0 signal which forces you do press the buttons. The real legitimate boards that are not che...

Re: Upload code without pressing EN and Boot buttons

Absolutely it will work. Don't you have one of those kits? Or any of the others ones like it? IF not buy one and you will see for yourself.

You do not need to push those buttons to set it up for flash mode.

Re: Upload code without pressing EN and Boot buttons

They have the buttons, but you do not need to use them. The circuit on the board takes care of the EN and GPIO line toggling when you go to flash it.

Re: Upload code without pressing EN and Boot buttons

Oh... Then just put the same circuit on the board as the ESP32 DevKitC. Look at the schematic on this page.

Re: Upload code without pressing EN and Boot buttons

All you need to do it route the following signals to a header of your choice on your PCB.
Power, GND, TX, RX, EN and GPIO0.

Then you can can just use one of these to program it.

Re: Dual Core Synchronization

Have you tried using claim_bus() and release_bus() ?

Re: IO_MUX and CS pin

If you want to disable all CS pins you would set sclk_io_num to -1 Take a look here: https://espressif-docs.readthedocs-hosted.com/projects/esp-idf/en/latest/api-reference/peripherals/spi_master.html#_CPPv4N16spi_bus_config_t11sclk_io_numE Then you can control your own CS using something like this. ...

Re: IO_MUX and CS pin

If you are working with Arduino I cannot say, but if ESP-IDF you can.

Espressif, Thank you!

We have been using the ESP32 in many projects for about a year now. Never had one issue. For us, it works great and it has become our main go to device. Last week, my boss asked me to investigate the Kendryte 210. I am glad he did because after much researching it made me appreciate Espressif far, f...
