Yes, it's working fine now. 4096 samples retrieved with no lost. Here is the last version with a spin button for threshold tuning. PicoV1.jpeg The gtk widget "curve" is used to display the signal. This widget is deprecated by gtk developers. Does somebody know or use a gtk graphical tool that could ...

Hi,
Sorry for this silly question (in very poor english).
I haven't seen that parameters 2 and 3 of ps5000aRunBlock function give the number
of required samples.
Here is a better code.

Hi, I am still writing a C-code to communicate with my 5244B Picoscope. After some troubles with the ps5000aOpenUnit everything seems to be ok. Thanks to Hitesh for his help on this first problem. The C-code is written with the graphical library gtk+. The program is very simple. It displays a window...

Thanks, it seems to be ok now.
The returned value is 0 (PICO_OK) and the red led in front of the Pico turned off.

Well, it's not so good.
If we check the 11a return value in the documentation. It's better than 3f (PICO_NOT_USED).
11a gives : PICO_POWER_SUPPLY_NOT_CONNECTED.
Perhaps it means that an external power supply is mandatory to play with this library ...

Good !
It's working with PS5000A_DR_8BIT.
The display is :

handle : 1
device : 11a
channel : 0

Thank you very much.

Here is the very simple code (perhaps too simple) : #include #include "PicoStatus.h" #include "ps5000aApi.h" main(){ int16_t handle,nb,serialLg=80; char serial[80]; PICO_STATUS device,channel; printf("Hello Picoscope\n"); device=ps5000aEnumerateUnits(&nb,serial,&serialLg); printf("Number o...

Hi Hitesh,
Thank you for your help.
I'm using a 5244A dual channel Picoscope and I'm using the dual-headed USB cable.
I have also tried to plug the power head in an auxiliary PC USB port and the second head in the Rasp.
No result.

Hi Hitesh,
Yes, I have tried running it with sudo command or as root.
Do you think that the raspberry usb ports give enough current for the picoscope ?
The pico is supplied with a double usb plug. Perhaps should I use an external power unit.

Hi, I'm a new user of the libps5000a.so library with gcc on a Raspberry. I have written my first C program with this library. No problem for linking and the functions are fully called by the main program. The first I've used is : ps5000aEnumerateUnits. It gives results. The picoscope is detected, it...

Hi,
Im a french user of a Picoscope 5240A and I hope, one day, it will be able to communicate with my Raspberry 2B.
Thank you for your help.
