Hi Thomas,
Sorry it took me awhile getting around to posting this, but here is
the patch to get the ftdi_read_pins function working in Python:
chris@ubuntu:~/Desktop/libftdi$ git diff
diff --git a/bindings/ftdi.i b/bindings/ftdi.i
index 1fc2a59..ab33d4c 100644
--- a/bindings/ftdi.i
+++ b/bindings/ftdi.i
@@ -3,8 +3,11 @@
%include "typemaps.i"
%include "cpointer.i"
%pointer_functions(unsigned int, uintp);
+%pointer_functions(unsigned char *, ucharp);
+%pointer_functions(char *, charp);
%typemap(in) unsigned char* = char*;
+
%ignore ftdi_write_data_async;
%ignore ftdi_async_complete;
I'm far from an expert in SWIG, but this appears to be working nicely.
Here is a some sample code that I'm using to read the pin state:
def ReadPins():
pins = ftdi.new_charp()
ret = ftdi.ftdi_read_pins(ftdic,pins)
return ftdi.charp_value(pins)
Hope that is helpful for the community.
Thanks for all the great work on this library!
Best regards,
Chris
