i would like to do a project of electronic noticeboard using a microcontroller pic16f628 for my diploma but do not have the knowhow. could you please help me. i know that i need a gsm modem, a db9 connector and 16x2 lcd. i dont know the connections.
thank you mr rb abd allen. i now kon the connections but i dont have the code. i am using pic16f628a connected to gsm modem through a max232. i am also using lcd hitachi 16x2. can anyone help. c or assmbly language.
thank you mr rb and allen. i now have the knowledge how to do the connections but i dont have the code. i connected the gsm modem to pic16f628a through max232 and i am using hitachi 16x2 lcd. can anyone help please.
hie. i have a usb gsm modem and i would like to interface it with a pic16f628a. these are available on the local market and other options are not available. the problem is i have a usb to rs232 serial adapter. can i use this by providing the 5v to vcc of usb and use max232 between rs232 and microcontroller. if its possible to do so is there need for a specific program for that.
Instead of using the USB->RS232 adapter, I would just buy a USB->TTLserial adapter. They are about $3, and will allow you to directly connect to the PIC USART pins.
thank you friends for your help i managed to do the project. i used pic 16f876, gsm modem dual band Q2403 with RS232 interface and max232. the project was partially working as i was able to send a message whenever a new message comes but i could not decode the message such that it could be displayed on the noticeboard. meaningless text was displayed on the lcd. i just want to rectify the problem out of intrest.
