buspirate's Issues

Voltmeter mode doesn't work

Voltmetr mode of ADC produced never ending series of values. It doesn't work. Well, BusPirate is switched to voltmeter mode but this Python script doesn't read values. Voltage values are not separated by new line but rewritten in place with "0x08" control codes.

Example, test.txt:

d
d
D

Serial console, BusPirate:

BTW, I miss possibility to have comments in BusPirate scripts...

Allow basic datalogging

As PSLLSP commented in #1 , the program is not very well suited for datalogging.

Review possibilities and make a first approach

Allow comments in scripts

As PSLLSP commented in #1 , it would be nice to be able to add comments to the scripts

configurable timout

I found this Python script interesting to upload and run BASIC scripts to BusPirate device. It works great for scripts that are fast. An example:

$ cat test6.bp 
s
new
10 AUX 1
20 FOR I=1 TO 5
30 LET A=ADC
40 PRINT I;": ";A
50 DELAY 20
60 NEXT I
70 AUX 0
80 PRINT "WORK DONE"
list
run
exit

$ python3 buspirate.py -c /dev/ttyUSB2 test6.bp

- Closing serial port

Other scripts, those run longer, are not able to finish because TIMOUT is triggered and Python session is closed. I have to run these scripts from terminal (like minicom or picocom). An example, the same script as before but it runs longer (DELAY increased from 20 to 100):

$ cat test6a.bp 
s
new
10 AUX 1
20 FOR I=1 TO 5
30 LET A=ADC
40 PRINT I;": ";A
50 DELAY 100
60 NEXT I
70 AUX 0
80 PRINT "WORK DONE"
list
run
exit

$ python3 buspirate.py -c /dev/ttyUSB2 test6a.bp

So I think it could be helpful to have a way to tell Python program to wait longer before TIMOUT disconnects it from the BP. I am not sure what is the best way to do it. The BASIC program can run on BP device for hours...

BASIC mode is not detected

When BusPirate device is in BASIC mode, it doesn't accept commands like #. This Python script runner is very useful to upload BASIC script to BusPirate but it doesn't detect if BusPirate is in BASIC mode and sends RESET command # as the first command during communication with BusPirate. exit is the command to leave BASIC mode...

$ cat test2.bp 
s
10 print "Hello World!"
list

$ python3 buspirate.py -c /dev/ttyUSB2 test2.bp

When BP is not in BASIC mode, in most cases, initial RESET works:
