HSPI not working on ESP_LAUNCHER dev board

Postby pirlouwi » Tue Feb 23, 2016 7:41 pm


I have some experience with ESP-01 and ESP-03 modules.
I have written some C code on it, using the Arduino adaptation layer.
With this code, I got an application that uses the HSPI port of the ESP8266EX to connect to a SPI accelerometer (ADXL362).

My problem is that the same application does not work at all on the ESP_LAUNCHER board.

I see on scope that SCK signal and CS signals are moving as expected, but MISO and MOSI remain steady.

Any help would be appreciated.

Shematic and PCB layout of ESP-LAUCHER can be obtained in below link.


If you want to use HSPI interface, please try to remove C8(besides reset key) and R58(besides IR-emitter diode) first.

More questions, please let us know.
