Connections between 18F452 and WIFI CLICK PLUS

[molec]

Hi (from Tunisia),

I don't own the board EasyPic7 (only Easypic5) and I wish to construct a self made board with 18F452 and WIFI CLICK PLUS.

I am studying connections between µc and module wifi and I ask me:

There is the wires i a have identify:

Side PIC 18F452 Side WIFI CLICK PLUS

1: RA3 ------------------------------------------ AN
2: RE2 ------------------------------------------ RST >>>EXT 3,3V ------ 3,3V
3: GND ----------------------------------------- GND
4: RC1 ------------------------------------------ PWM
5: RB1, INT1 ----------- R=1K ------------------- INT
6: RC7, RX -------------------------------------- RX
7: RC6, TX -------------------------------------- TX
8: RC3, SCL ------------------------------------- SCL
9: RC4, SDA ------------------------------------- SDA

I Think that only wire 2,3,6,7,8,9 are really essentials and used by Net_Wireless_MCW1001 library.
1,4,5 are not really used...

1. Is that idea correct?
2. For each of the 8 connections described below:
Is it essential?
Is it useful?
Is it used by Net_Wireless_MCW1001 library?

Thanks for your response to confirm my project. Best regards..

Hello,

For basic connection you need only 5 pins. Two for power supply, two for communication (RX/TX) and RST pin(it's not 3.3V it's used by library).
You need to set RST pin for example:

Code: Select all

sbit Net_Wireless_MCW1001_Chip_RST           at RE2_bit;
sbit Net_Wireless_MCW1001_Chip_RST_Direction at TRISE2_bit;

Doesn't need to be RE2, you can chose some other MCU pin.

Best regards.
