I need 5 pins from the ESP.
I have used for other purposes a few of them (GPIO14,GPIO12, GPIO13, GPIO15, GPIO4, GPIO5).
Between RESET and GPIO16 I will add a diode for wake up from deep sleep.
So have been left free: ADC, CH_PD, TXD, RXD, GPIO0, GPIO2, CS0, MISO, GPIO9, GPIO10, MOSI, SCLK.
Can I use any of these or I have ro remove any of them from the list?
