enhanced modified console example from SDK

Post by rjm »

Besides some changes in functions that address my needs, I created the opportunity to invoke the console control application with a configuration file. Such a config file would process commands before the prompt is shown and as such it allows me to work on preset configurations.

I start with a sample of a config file:

Code: Select all

# hi! I'm the start of a command file...
d12
vb0
vc0
vd0
va200
# set up generator as a calibration resource (10 mV RMS)
gws
gf500000
gv14.14
# intend to get 125 MSPS
i 3
#b31250000i |./anyprocess > data.txt
Sample invocation (in Linux):

Code: Select all

$ ./picocontrol control.txt 
PicoScope 5000 Series (A API) Driver Example Program

Enumerating Units...
*** A command batch file control.txt will be executed after enumeration ***

Command Summary:
T - Triggered block
E - Collect a block of data using ETS         A - ADC counts/mV
R - Collect set of rapid captures
S - Immediate streaming
W - Triggered streaming
D - Set resolution [8 | 12 | 14 | 15 | 16] bits
I - Set timebase
V - Set voltages (FS-range) in mV
B - Immediate block
G - Signal generator (optional) [ Wave | Freq. | Volt/Ampl.]
X - Exit
*** Enter '?' for specific command help ***

Source code is attached (based on ps5000acon from 2017), where the binary name is picocontrol.
The block data handler is modified such that you can pipe the captured data to another process.
