This project aims to convert flex sensor (installed on fingers) signs Into binary values that will be translated based on customized dictionary to strings that are pronounced by peripheral device.
don't forget to change slave address in (LDCI2C_CFG.h)..
in the prouteos simulation PCF8574 adress was 0x020 (a0,a1,a2->ground)
but for the physical LCD i used (PCF8574T-I2C-1602-16X2-LCD) address was 0x27

FLEX SENSORS Are represented as resistors (they actually are.) but one of them is a potentiometer so you can simulate how changing resistance change the behaviour (in proteus) ..... DO NOT FORGET TO Invert RXD AND TXD Pins if you are using USB to TTL as in the simulation i'm connecting two ports using a virtual ports program.. However in real life you'll be using one port (usb to ttl) and the data recieved from TXD(usb) should go to pin RXD(micro_controller) data sent through TXD(micro_controller) should go to pin RXD(usb)

I will update more information on a PDF file that explains everything later (after the porject discussion) so wish me luck
update you can find the PDF file now on: deaf_gloves/69t8li0rcy1q2374LY.pdf
