Proton PICBASIC vs MeLabs PICBASIC

[Luciano]

I don't use Mikrobasic, but here is an easy way to do it without interrupts...just translate the code to proper syntax. (And set the symbols of cTxReg etc. to the appropriate values. Leading characters are: c=constant, b=byte.)

bDelayTime = 0
CheckForData:
if cTxReg = cDataWaiting then 'check hardware Tx register for incoming data.
serin = bSerialDataIn 'get data...
goto SerialDataReceived
else 'no data waiting...
pause 1 'wait 1ms...change to match your baud rate, since some speed may overwrite
bDelayTime = bDelayTime + 1
if bDelayTime = cMaxWaitTime then
goto NoSerialDataReceived
endif
goto CheckForData
endif

Hi,

Your code does not work with software UARTs.

Software UART routines use bit-banging techniques and can use almost any I/O pin
of the microcontroller. Software UARTs have big limitations and if the microcontroller has
hardware UARTs just use them!

Best regards,

Luciano

Your code does not work with software UARTs.

This is absolutely true.

One nice thing about Proton+ is in the forum, Les the compiler author occasionally posts misc. PDS code. (In addition to helping out on the forum when needed.) For instance, he's posted a full Space Invaders game that works with the Crownhill development board... which is modeled in the VSM simulator so you can play it right on your PC screen (or the actual development board).

He's also posted code to use as a serial buffer for the hardware usart, so it will receive data in the background, and fill it in when you get around to using a hserin command. More examples are speech decompression routines, and a full .wav file player design with CF FAT and audio out routines.

These are just a few examples. Some of them can easily be ported to PBP; others may take some work.
