read serial and post to LCD

Unread postby jbates58 » Sun Apr 23, 2017 7:50 pm

hi all

i have a device that outputs serial information as 19200 baud.

i am wondering how i can interface this unit to my SHOW?

can i simply put it through the a4/a5 pins? and then can i send that information to the LCD?

Cheers

Jason

ok, so after some reading, i think the device outputs via a uart.

i am able to connect my pc and phone to it via a usb-ftdi adaptor. if that helps.

The HW UART port is connected to the USB-to-UART chip as described in this WiKi page.

So you might need to use SW UART (GPIO bitbang) with 2 pins of GPIO on 6pin IO ports
