sigrok has been removed from the standard build, because the support from sigrok side is very poor. That means there has to be several extra miles to go until sigrok is actually working with YaPicoprobe.
Additionally a lot of use cases of sigrok can be covered by SystemView in the embedded area.
This document holds some information about how to use sigrok after compiling it into your own YaPicoprobe.
The probe allows data collection for a sigrok compatible environment. Meaning the probe can act also as a logic analyzer / oscilloscope backend. The module is based on work taken from sigrok-pico. This also means, that at the moment libsigrok has to be adopted accordingly, see here. Benefit is, that this allows the Pico as a mixed-signal device and RLE compression of the collected data.
Specification of the module is:
-
8 digital channels at GP10..GP17
-
3 analog channels at GP26..GP28 with 8bit resolution
-
internal buffer of 100KByte which allows depending on setup between 25000 and two hundred thousand samples with highest sample speed
-
digital sampling rate can be up to 100MHz for a short period of time, see here
-
analog sampling rate can be up to 500kHz with one channel
-
continuous digital sampling can be up to 10MHz depending on data stream and USB connection/load
-
auto-trigger for sampling rates ⇐ 24MHz
Drawbacks:
-
digital channel numbering in sigrok is confusing, because D2 corresponds to GP10…
-
for best performance digital channels must be assigned from GP10 consecutively
-
currently no hardware triggering supported
