FlexProp Spin2 possible problems

Rsadeika

This is the results of trying to compile, using FlexProp GUI, a Spin2 file, jm_dhtxx_demo.spin2. Below I have included the zip file that Jon provided.

I wanted to run the Spin2 code visually to see what the program looked like, before I started to port it to FlexBasic.

You know, Eric charges nothing for his compiler -- perhaps you could have tracked down the errors and provided suggestions. You are a programmer, right?

It took about 2 minutes to modify the code to run in FlexProp. I'm documenting the changes here to assist @ersmith.

This is a known issue that was reported a few days ago.

  getms()   ' Spin2 compiler
  _getms()  ' FlexProp

Syntax changes:

  dht[x].[y] := b

...is changed to

  dht[x] |= b << y

...for FlexProp.

  if (dht[2].[7])

...changes to

  if (dht[2] & $80)

...for FlexProp.

Visual proof is attached. Make sure you add -T to the Run command line.

@Rsadeika , @JonnyMac : Thanks for the info guys. getms() was added in 5.0.6, which is on my patreon page and will be on github soon. The dht[x].[y] syntax was supposed to work, but parsed incorrectly due to a typo in the parser. The _ret_ condition code never got implemented for inline assembly (it needs special handling because FlexProp puts inline assembly inline, in constrast to PNut which makes it a subroutine) but that should be fixed now. Both changes are checked in to github and will be in the next release.
