**<mark>Notice1：M5PORT EXPLAIN</mark>**
|
||||
You can identify the port name and function by its color, red is PortA(21/22) mainly used for I2C, black is PortB(26/36) which can be used for DA/AD, Singel-bus communication, Blue is PortC(16/17) can be used for Uart. Correspondingly, most of the M5 Units have the Port with matched color for specify which port it should go in on the M5Core.
|
||||
Those port identification is a convenience for UIFlow (Blockly) Users. For advanced using ,you can do you own customization, since most of the PIN on ESP32 are remapping-able.
|
||||
Unfortunatly, PortA(red) can not be used as analog read in. It refers to GPIO 21 & 22 from ESP32, which doesn't have AD channel alternatives:
|
||||
|
||||
- ADC1(8 channels atteched to GPIOs 32-39)
|
||||
- ADC2(10 channels atteched to GPIOs 0，2，4，12-15，25-27)
|
||||
- ESP32 has two 8-bit DAC (digital to analog converter) channels, connected to GPIO25 (Channel 1) and GPIO26 (Channel 2)

To use AD read function :
|
||||
1, Use Dupont cable refers to the pins on the side which can be used as an AD channel.
|
||||
2, Get a M5GO bottom, which comes with a PortB.
|
||||
3, Get a PbHUB and connect it with PortA, then you can have 6 PortBs.
