spi slave example
Posted: Fri Jul 21, 2017 12:34 am
Hi,
I'm new with esp32.
I'm trying to get data from esp32 by a spi connection.
Esp32 is the slave and a texas msp430 is the master. Esp32 firmware is the example SPI-slave in the idf examples.
When the master requires for the data the esp32 returns data and after gets this error:
A file missing? Where have I to put it?
Thank you very much for your help
