Most of the issues should be fixed in libsigrok since 16.12.2019 and are now available in the SmuView 0.0.4 binaries.

Hi robofreak,
looks like a bug in the sigrok rdtech-dps driver, or more specific in the modbus CRC check (modbus_serial_rtu.c -> modbus_serial_rtu_read_end()).
Could you start SmuView with the "-l 5" argument, connect the device and attach the log. Maybe the log contains more info about the CRC check.
I don't own one of the RDTech power supplies and therefore I can't debug the problem myself.
Furthermore the driver is missing a mutex. That's a generic fix I can add, when the CRC check is working.

had the same error with sigrok-cli. So it is a bug in the driver.
I send one or two hours investigation this bug, but without any real success

Thank you, for your fast response.
This was my first guess too, that this is a sigrok specific error. But with the sigrok-cli (v0.7.1) the power supply is detected and works.
./sigrok-cli-0.7.1-x86_64.AppImage -d rdtech-dps:conn=/dev/ttyUSB0 --scan
The following devices were found:

Here is the log from smuview. I see it is linked again sigrok v0.6. So maybe this error is already fixed in newer sigrok versions:

I've looked into the driver code, but without the device there is not much i can do. Unfortunately, the logs you attached doesn't help either.
I'm going to add a bunch of log outputs to the relevant parts and post an AppImage here asap. Maybe I get a clue somehow :)
Perhaps the error occurs so fast with SmuView because of the missing mutex? I'll add the mutex in the test AppImage too.
But that sounds like a sporadic error. Maybe the device sends a wrong checksum sometimes? Hopefully more log output will tell...
@littleyoda : You have a Korad psu, don't you? It would be great, if you could confirm the thing with the unreliable buttons and check if my fix is working (issue #7 ).

My Modell of the Korad psu do not have these buttons. Sorry, can not test it :-(

I have done some further investigation. When thesigrok-cli is running in log level 5 I can see the crc error occuring, when the USB connection has been closed.
So this explains the different behaviours between the sigrok-cli and the smuview app. The smuview app closes the connection after init. The sigrok-cli keeps the connection open until you close the program itself.

Hi robotfreak,
are you able to compile libsigrok/sigrok-cli/smuview by yourself? I've added the missing mutex and a whole bunch of debug output for the RDTech psu to my branch "patches": https://github.com/knarfS/libsigrok/commits/patches
Otherwise I can create an AppImage at the end of this week.
You don't need to add "-l 5" for the log output this time.
I don't know if we will see some useful info in the outputs, but i hope so.

Hi knarfS,
success. I got it working. The only change I made, is in the rdtech_dps_capture_start function. Setting devc->expecting_registers to 0, instead of 2. Not sure if this is the right way to fix it, but for me it works. Now the device_close function will never read any pending data.
SR_PRIV int rdtech_dps_capture_start(const struct sr_dev_inst *sdi)
{
struct dev_context *devc;
struct sr_modbus_dev_inst *modbus;
int ret;
devc = sdi->priv;
modbus = sdi->conn;
g_mutex_lock(&devc->rw_mutex);
sr_err("rdtech_dps_capture_start(): -1-");
if ((ret = sr_modbus_read_holding_registers(modbus, REG_UOUT, 3, NULL)) == SR_OK)
devc->expecting_registers = 0;
sr_err("rdtech_dps_capture_start(): -2- ret = %i", ret);
g_mutex_unlock(&devc->rw_mutex);
return ret;
}

The CRC error was a red herring and only a subsequent error... :(
The actual error hasn't any interesting log output, but at least I can narrow it down.
I don't think your fix solved the actual error, though the expecting_registers thing doesn't make much sense the way it is implemented...
I updated my branch with more log output in the interesting parts. Would be great if you could attach a log without your patch and one with.
Sorry, but I rebased my patch branch, you have to "git fetch --all && git reset --hard origin/patches".

Now I get a memory access violation error with or without my patch the log output looks the same:

Development moved to https://github.com/knarfS/libsigrok/tree/patches2
Both tests failed, when trying to get the ovp_active config key. The code for getting the config key looks OK, as far as I can tell.
Could you try to get the key with sigrok-cli (replace conn string with your settings):
sigrok-cli -d rdtech-dps:conn=/dev/ttyUSB0 --get ovp_active -l 5
This will probably fail too:
sigrok-cli -d rdtech-dps:conn=/dev/ttyUSB0 --get ocp_active -l 5
Next thing I can do is deactivate this two config key and then testing if there are other config keys that are failing.
But without the device it is very hard to tell what's wrong with those config keys...

I think I got it! It was hopefully only a timeout that was set to low.
Please attach another log output, so I can properly adjust the timeout.

Here are the log files. The serial_read_blocking time varies from 33...124 for ovp, 19...91 for ocp.

The important duration is 1st serial_read_blocking() in modbus_serial_rtu_read_begin() which is around 450ms. Pretty close to the former timeout of 500ms.
But the most important question: Is SmuView working now?

Yeah, but my assumption was right ;) However the timeout of 1000ms was still to low...
I increased the timeout to 5s, that should hopefully be enough.

It's again the timeout. Seems like sometimes 5s isn't enough. Puhhh....
Could you play around with the timeout by yourself? You'll find it in src/modbus/modbus_serial_rtu.c, line 148. I'd start with 20000ms (THAT should be enough) and then look at the time in the log ("modbus_serial_rtu_read_begin(): 1st serial_read_blocking() time =") and adjust it down. When SmuView is running stable, start to change the output voltage, current, toggle the output, etc. to stress the power supplies lil' CPU and check if the duration of the serial_read_blocking() is rising...

Sorry, but I don't get the timeout working. Even 40s isn't enough. At the moment the chances are 50:50 to start smuview succesfsully. If smuview starts successfully, the blocking time is always less than 5s.

Sorry for the late reply.
I pushed a possible workaround to my patches2 branch (rebased!): The sr_modbus_read_holding_registers() function is now called up to 3 times if it fails. i also decreased the timeout back to reasonable 600ms.
Let's see if it's working now...

I moved the patches for the RDTech power supplies back to my branch "patches" (https://github.com/knarfS/libsigrok/commits/patches).
I refined the commits (a few debug outputs are left, but will be removed before I make a pull request).
I also added meta packages: When the regulation (CV/CC) or the output state changes or one of the protections (OVP/OCP) is triggered, that will be displayed in SmuView.
I would be happy, if you could test my changes again and append a log file with log level 5 (./smuview -l 5)

Most of the issues should be fixed in libsigrok since 16.12.2019 and are now available in the SmuView 0.0.4 binaries.
Can anyone confirm that the x86_64 appimage from 0.0.4 is working for the DPS? I tried on both Windows and Ubuntu and experienced the same CRC error with the files from the latest release. I've confirmed that the DPS works properly using RD Tech's software on Windows, so I don't think it's a problem on my hardware. I tried building from source on Ubuntu and ran into python issues using either the method from the SmuView manual or the Sigrok Building from Source page.

I've implemented a workaround in the sigrok driver for the DPS devices some time ago (see sigrokproject/libsigrok@aff2094). Because I don't own one of those PSUs, I can't do a proper investigation of that problem.
What I can tell so far: Sometimes the device doesn't respond to the "read holding registers" modbus command. The workaround tries to read the registers up to 3 times.
Somebody with that devices has to do some deeper investigation and maybe debug the protocol the vendor is using in its software and tweak the sigrok driver.
I tried building from source on Ubuntu and ran into python issues using either the method from the SmuView manual or the Sigrok Building from Source page.
Can you give some details about that (CMake and/or make output)? Probably a missing dependency or something similar. Maybe open a new issue.
