CW Keyer

[Peter Hiltz]

All,

First the good news.  I built a simple TR board and installed wsjtx and, into a rainspout antenna - very inefficient but tunes up - had one wspr spot.  So the TR board works and I was able to create virtual connection between pihpsdr and wsjtx.

Now, the current PROBLEM.  I'm trying to get CW to work and while I can successfully install both flavors of pihpsdr, CW and no-CW, the no-CW version will not find the radioberry.  It either gives no signal on the panadaptor or waterfall, or a large spike in the middle of the display.

In addition, following the directions at 

https://github.com/pa3gsb/Radioberry-2.x/wiki/piHPSDR-running-CW-mode

I do not get the same gpio display as on the page.  Mine simply displays text of GPIOA  GPIOB etc, but nothing is selectable.  

Reading the group shows some folks with success but nothing I can parse out to tell me what I've missed.  Any guidance would be appreciated

73, Pete WV3S

Pete,

Can you give some more detail; some print screens?

Hi  Pete, 

Is this correct? "yes-CW" version of the pihpsdr does not signal pana or waterfall.

If right, this is related to the updated pihpsdr from last July or August. (> the gpiod branch merged.??)
and need to build with "no-CW" to get it to work.

If use the rc15 version of the pihpsdr, CW keyer will work.
however, the CWL and CWR pin assignments changed in the latest gateware. (gw73.2 Sep.2021)

so,  need to set pins in the configure gpio for gw73.2:  CWL GPIO = 0, CWR GPIO = 29.

hope this help.

Hi Group,

FYT. I'v tried with RPi's newer OS..
  Raspbiasn 32bit "Bullseye" R11 2021-10-30, GCC:10.2.1

<OK, worked>  Pict.1
 pihpsdr: no-cw (latest v2.0.8-rc1) and radioberry (latest: gw73.2, drv0.93 fw2021.09.26)  
 and external key worked.  but no cw keyer.

<Not worked>
 pihpsdr: yes-cw (latest v2.0.8-rc1) and radioberry (latest: gw73.2, drv0.93 fw2021.09.26)

<Compile Error in older versions of pihpsdr.  Not worked>
 pihpsdr: yes-cw (older v2.0.0-rc15) and radioberry (latest: gw73.2, drv0.93 fw2021.09.26)
 Installed wiringpi v2.52 then compile ok, but didn't work...  Pict2

Yado-san, did you ever figure out a solution? Making a board for all the I/O jacks here, and it's good to see PTT and straight key work, but unable to test paddles and sidetone currently due to this.

Thanks,

KD

[Yado-san]

Hi KD,

Sorry, I did't solve this due to my skills.
I'm running piHPSDR with
: RPi OS：   Buster（R10）
: piHPSDR : v2.0.0-rc15

Yeah, I can't even find that version of pihpsdr, I did try 2.0.0-rc10 to no avail. Multiple commits have the same version number, so the number doesn't necessarily mean anything. Rather difficult to test my I/O jacks, also see things like neither INTTR or EXTTR goes low on TX with pihpsdr, yet they both do if I use SparkSDR, even when I uncheck enable PA.

Hi All,

I tried this morning the cw key option in pihpsdr. Installed the latest release. Also installed the pihpsdr; latest version.

For me it is working;  Show my setup in pictures:

Johan, are you not using your install scripts? It would appear you aren't as you've got a version of pihpsdr that is over 2 years old. I just did a new install myself, I will detail it:

1. Installed this image: https://downloads.raspberrypi.org/raspios_full_armhf/images/raspios_full_armhf-2022-01-28/2022-01-28-raspios-bullseye-armhf-full.zip

2. Set timezone/install all updates/etc after initial boot.

3. Enabled I2C via raspi-config

4. Downloaded/executed this shell script: https://raw.githubusercontent.com/pa3gsb/Radioberry-2.x/master/SBC/rpi-4/releases/dev/radioberry_install.sh

5. Verified installation:

pi@raspberrypi:/tmp $ sudo systemctl stop radioberry
pi@raspberrypi:/tmp $ sudo radioberry

====================================================================
====================================================================
                        Radioberry V2.0


        Supports 4 receivers and 1 transmitter.

        Build version: 2022.01.24

        Have fun Johan PA3GSB

Radioberry gateware version 73-3.

6. Downloaded/executed shell script https://raw.githubusercontent.com/pa3gsb/Radioberry-2.x/master/SBC/rpi-4/releases/dev/pihpsdr_install.sh , chose wdsp. Executed again, chose pihpsdr, chose yes for local CW option. Here is what I get:

I have verified the hardware is working by installing wiringpi 2.52, then executing "watch -n 0.1 gpio readall". I see GPIO.29 change state on dit, and GPIO.0 change state on dah.

All,

I concur with Kristofer in that I just reinstalled from the releases page and see no change in performance.

However, there may be an answer here........ Can anyone confirm that the radioberry toggles GPIO.29 on a dit and GPIO.0 on a dash?  If true, then a change of pin definition in pihpsdr before compile/install might be the solution, though you'd have to put in the change after downloading pihpsdr and before compile/install, which deletes the download as a clean-up action.

Pete:

cd /tmp wget https://project-downloads.drogon.net/wiringpi-latest.deb sudo dpkg -i wiringpi-latest.deb

Then run "watch -n 0.1 gpio readall". Look at the V column while you key, you should see GPIO.29 and GPIO.0 change from 1 to 0 when you key.

Hi,

My bad... i did a pull ; did a build but used the icon to start pihpsdr.

Looked into the code did a few mods and it is working.

Need to make a pull request to get it in the pihpsdr repo.

Hi Johan, unfortunately I still get this.

However, I do get dits now, but on both paddles and on straight key also. Doesn't matter if software is set for straight, mode a, or mode b, I still get dits on all 3. If I checkbox keys reversed, then I get dahs on all 3. Checked the other I/O, the PTT switch works, and both INTTR and EXTTR go low on TX as they should.

The gpio pins are fixed for radioberry; so you do not have the possiblity to choose ports! Your print is ok.

I have pushed a mod for the dih and dah; the gpio.c file is refactored to work with gpiod ; hope this mod will work for you.

Johan, progress made, I do have dits and dahs now. They are reversed, so the box needs to be checked. Straight key is still broken, is either a dit or dah depending on whether keys reversed is checked or not.

Hi Johan,

Thank you for the fix on pihpsdr!
I've confirmed that it works with the latest version of piHPSDR! (CW Option=Yes)
...I've been looking at 'gpio.c' since last summer and couldn't solve it, sorry...

Before gpio.c change: pihpsdr did not work, 
After, piHPSDR works. also CW Keyer (dih/dah) work.   Attached
