Use SPI and I2C at the same time on WiPy 3.0
Posted: Wed Jan 23, 2019 1:35 pm
For my project I've to use WiPy 3.0 with expansion board, as3993 rfid reader and MPU9250 sensor. For the Mpu9250 sensor I use I2C interface with default pins P10 and P11 for SDA and SCL respectively. But for as3993 reader I've to use SPI interface, because it supports only this interface. And the reader requires following pins: MOSI, MISO, IRQ, SCLK(CLK), NCS (CS), CLSYS. If MOSI, MISO, SCLK pins are known as P11, P14, P10, but about IRQ, NCS (CS), CLSYS pins i cant find information. Should I assign these pins by myself or are they already defined on the board itself? As datasheet i use it: https://docs.pycom.io/.gitbook/assets/wipy3-pinout.pdf
As well, will it possible to use at the same time I2C and SPI interfaces if they use the same pins or should I assign another pins?
