Helll i need the pinout of the gpio of the Esp C3 ProMicro de SparkFun. Where can i obtein? Thanks.
Just click on the things on the product page
I dont understand where are the pins of
. MOSI
. MISO
. SDA(SS)
. SCK
. RST
Click the 2nd link.
poci/pico are new names for the same things, everything else is labeled directly
I need define in the scketch two pins/gpios:
#define RST_PIN 21
#define SS_PIN 5
i inted with this and with:
#define RST_PIN 8
#define SS_PIN 19
and not function.
I need define whats are these pins/gpios.
I don’t understand the schematic.
In order to help : What do you connect to the pro micro and how do you connect (which cable where) ?
Try this :
Connect the RC522 Slave Select (SDA) to pin 10: #define SS_PIN 10
RST is an INPUT for the ESP32 pro micro. Do NOT connect unless you want to reset the ESP32.
Connect the RST from the RC522 to pin 7 : #define RST_PIN 7
The rest looked ok.
