The monitor command - what replaces monitor -ams at 0.95

[G4DCP]

Folks,

I'm a beginner with Red Pitaya. I want to look at Chip temps etc and the wiki gives the example:-

redpitaya> monitor -ams
#ID Desc Raw Val
0 Temp(0C-85C) a4f 51.634
1 AI0(0-3.5V) 1 0.002
2 AI1(0-3.5V) 13 0.033
3 AI2(0-3.5V) 1 0.002
4 AI3(0-3.5V) 2 0.003
5 AI4(5V0) 669 4.898
6 VCCPINT(1V0) 55c 1.005
7 VCCPAUX(1V8) 9a9 1.812
8 VCCBRAM(1V0) 55d 1.006
9 VCCINT(1V0) 55b 1.004
10 VCCAUX(1V8) 9ab 1.813
11 VCCDDR(1V5) 809 1.507
12 AO0(0-1.8V) 2b0000 0.496
13 AO1(0-1.8V) 150000 0.242
14 AO2(0-1.8V) 2b0000 0.496
15 AO3(0-1.8V) 220000 0.392

This seems to be what I need but the monitor command doesn't seem to have an -ams parameter any more!

What am I missing how do I get the chip temperature now?

Here I go realizing I missed an adequate search before I wrote a query!

viewtopic.php?p=3891#p3891

This answers the question but I now have to write some extra code.

Suggestions (/ queries / puzzles),

Why was this changed? Should it not have been kept although modified to get the data the new way? Changing it this way breaks peoples code.

Can someone update the wiki? I suppose the answer to that is I should do it myself. I will if I can.

My apology for the dumb question. My google fu missed the answer under software!

I now have to ask where these are documented I can't make sense of the temperature value:-

redpitaya> monitor -ams
redpitaya> monitor -?
redpitaya> monitor
monitor version 0.95-1-6deb253-6deb253

Usage:
read addr: address
write addr: address value
set slow DAC: -sdac AO0 AO1 AO2 AO3 [V]

2778
redpitaya> cat in_temp0_scale
123.040771484
redpitaya> cat in_temp0_offset

redpitaya>

So what is the temperature in degrees C I was expecting something between 0-85. My guess might be (2778-2219)/123.040771484 but that is 4.54....

Advice please.

Hi Peter,

I tried:

(raw - offset)/scale i.e. (2778--2219)/123.040771484

which gives 40.62

Hope that helps (and is correct)


Kind Regards,

Hi Julian,

Yes that helps. I should have thought of trying the offset the other way round!

Hopefully someone will come along and point me to where this is all documented?

At least I can progress now.

Many Thanks

Hi Peter,
did you make any progress regarding this topic by now?
I´m also trying to read the chip temperature of the RP and i´m stuck exactly at this point.

When i use Julian`s equation i always get values around 40°C. I measured directly after powering up the RP and after using it for about an hour. I think the temp should rise at least a few degrees when using it for a bit.

Best regards

Joschi

Hi,

We did make some changes on monitor tool.
For -ams function is disabled.
You can use following commands.
https://github.com/RedPitaya/RedPitaya/ ... dc/xadc.sh
Best, RP

Hi RP,
Thanks for the quick reply. The equation in the xadc.sh brings me the correct temp values.
The only little problem now is that i have to calculate manually. The bash on my RP cannot find the "bc" command for some reason. Any ideas?

Best regards
Joschi

Edit: My bad, i forgot to install the bc. Everything works now.

Many Thanks.

I have tried the new script and have it working.

./xadc.sh
in_temp0 = 49.33 °C
in_voltage0_vccint = 1.01 V
in_voltage1_vccaux = 1.01 V
in_voltage2_vccbram = 1.01 V
in_voltage3_vccpint = 1.01 V
in_voltage4_vccpaux = 1.81 V
in_voltage5_vccoddr = 1.50 V
in_voltage6_vrefp = .41 V
in_voltage7_vrefn = 0 V
in_voltage8 = 4.31 V
in_voltage9 = .67 V
in_voltage10 = .69 V
in_voltage11 = .52 V
in_voltage12 = .93 V

Hello Peter,

i wrote the script in /home directory it dosnt work.

redpitaya> ./xadc.sh
-bash: ./xadc.sh: Permission denied

Can you explain please how you did it?
Thank you.
