Issue 175 - fixed 2 ipm issues

[Dean Hall]

I just pushed fixes for Issue 175 to the mainline.
http://code.google.com/p/python-on-a-chip/issues/detail?id=175

This fixes 2 things:

Interactive mode (ipm) now prints characters as they arrive from the
target VM rather than collecting them and waiting until the
REPLY_TERMINATOR is received. For example, the following will print
in real time (without timing out):

ipm> import sys
ipm> for i in range(5):
.... sys.wait(5000)
.... print i
....
0
1
2
3
4

I also fixed the case where an embedded '0x04', which is the reply
terminator, would cause a disruption in the print stream.

BEFORE:
ipm> print "test\x04this"
testipm>

AFTER:
ipm> print "test\x04this"
testthis
ipm>

share and enjoy,

!!Dean

This is a very good thing for embedded applications, since most have a main loop which never terminates. I had hacked up something in ipm.py earlier to overcome this, but your solution is *much* better. Thanks!

Hi Bryan,

I have some issue with ipm >> can you please suggest me the workaround for the following issue 

When i load my sample script(test.py and the size is ~2KB only) from ipm prompt for multiple times( about 3 times), i am getting the following error.

Traceback (most recent call first):

  File "../lib/ipm.py", line 97, in ipm

  File "main.py", line 19, in main

MemoryError detected by heap.c:444

Can you please suggest me the workaround for this. 

Regards,

Jani Basha Shaik

Jani,

I'd guess you're running out of memory -- what does the source code say for line 444 of heap.c? One fix: reset your micro before running you sample script each time. The size of your script doesn't say how much memory it needs: a line like x = "bop" * 100 will take a lot of RAM!
