Just wondering if anyone has used GCBasic to create a UART-SPI bridge before. I've got a project going where I've bought some pre-fab components which use SPI. Also, I've got some wireless UART transceivers which I'd like to use, so I'm going to need a bridge.
I know I could just as easily use a MAX3100 chip, but I have 30+ 16F690's laying around, so I'd like to save the expense.
Anyone done this before and want to share? If not, I'm happy to share when (if) I'm successful (if anybody's interested).
Thanks,
Grant
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have played with pic16f648a's and Xbee modules, if that is what you are talking about. At the time, I just polled the hardware usart, and sent back a string upon receiving communication from the master. Since then, interrupts were implemented, and that is the direction I would go.
So in Main, have the slave(s) gather info from the SPI devices, and write the variables to their registers. Use the usart on interrupt command, to send back data to the master.
Probably not much help, but here was the slave code (polling method), and using the old hardware usart routine.
Main:
Loopx:
Character = ReceiveSerial
If flags.gotnewdata OFF then GOTO Loopx
If Character = 1 Then
TransmitSerial_Print("Hello")
Set Transmit On
End if
If Character = 0 Then Set Transmit Off
wait 2 sec
Set flags.gotnewdata OFF
wait 25 ms
goto Main
