morning folks!

hey abeljj[m]! how's it going?

Hi Bertl , I was trying to move `pac1720_info.sh` to daemon ,I can replicate the output there.

As in do we want to replicate what `pac1720_info.sh` with a command like `get pac1720Info` or do we want to break it down into various parts for ex `get ZED_5V` , `get HDN` etc.

but of course you can abstact away all the calculations

for example, the temperate reported from the Zynq can differ about 5-10deg from the actual temeprature

Why does this difference in temp occur ?

(and of low quality regarding temperature measurement :)

they are specific for each MicroZed, we could measure them by putting the MicroZed into a heat chamber or putting an external sensor on the Zynq

yes , that would be good

well, the real question here should be: what will those values be used for

the let's break down the values from the script

[1e80] is the value read from the pac1720 register

both refer to the measured voltage

+8.8672 mV is the conversion to human readable form

and What are these 'ZED_5V' , 'HDN' ,'HDS' .. things

the first column is an abbreviation for those rails

so for example, RFW_V means Routing Fabric West supply Voltage

the power rails for the interface and sensor board have two 'directions'

Ok, is there some manual where I can find all these , would help alot to give suitable names to variables

Couldn't get anything from the schematics

IOW_V, VCCO_13 , HDN ,S_VS ,these should be suffice for figuring out the remaining

VCCIO_13 is terminology from the Zynq and refers to the Bank 13 I/O voltage

(or CSO_NE_V)

(not that S_VS exists :)

ah, ignore that comment about S_VS

S_VE = South East Voltage rail, S_VS = South Voltage rail, S_VW = South West Voltage rail

np

evening everyone!

good evening

welcome everyone

please again message me in the good old fashion if you want to report

Great!

I will continue by doing this, and this is my last exams week, so soon I will have my full time for this!

yeah, we should discuss this after the meeting in the remote channel

thanks, fares your up

I have been working on refactoring the code to allow for different configurations for different use cases. I also did two main configurations for micro and beta and those that I will be concentrating on them

and mainly I will test one more idea then move on to complete the 0xFF fixer and do proper testing to the new code.

I'm targeting 200MHZ with two pixels/clk for beta and 200MHZ with one pixel/clk for the micro, the timing is met in almost all component, some of them I needed to register the input before the logic - the components after fifo - but they work, only one module that I'm currently working on which have the big shift operation, but I believe 200MHZ is doable, the utilization should be less than 1k lut and 1k ff

great! that would be all.

aSobhy: your turn!

for the past week I finshed the ZYNQ side and wrote the link training at the MachXO2 side what remains is the deserializer thats I am on it

thats all

thanks aSobhy

Yes, se6astian

Last Week, Some refactoring for MLVLoader was done as functions like MLvLoader::load got rather big and i have commited the code also.

Right now, i am trying to use implemented allocators for playback and I hope, It should be completed in the first half of this week.

Thanks !

Y_G: please go ahead

This week I completed the I2CAdapter ,and tested it with a test module(replicates `pac1720_info.sh`) in beta.

Also I went through the scripts to check which adapter each scripts would use when and if moved to daemon.

thanks Y_G

Hi everyone :)

wonderful, please share some details :)

I have pushed the source of rtl for machXO2 and D3XX C++ code here --> https://github.com/apurvanandan1997/usb-plug-mod/tree/master/MachXO2

sounds great!

The makefile on this repo is not working currently , I will correct that soon.

That was from my side this week :)

On how things work and some advice you want us to follow etc.

great, thanks

The AXIOM Beta compact enclosure prototype parts arrived mid last week and we started putting them together on friday

good news: it does :)

thats it from me for this week

thanks!

I did write some test code for the new oscillator on the Axiom Remote

code can be found here: http://vserver.13thfloor.at/Stuff/AXIOM/REMOTE/

the current version implements a serial interface (CDC/ACM) but I think HID might be quite appealing for the remote as well

that's it from my side.

do you want to talk about the laser cutter as well?

ok, thanks

Would you like to share some information about first evaluation?

the GSoC evaluation coming up

its something each mentor does for his students individually

if there is feedback prior to the evaluations it should be done in private between mentor/student

thanks comradekingu

looks good :)

is it remotely interesting?

yes :)

a bit later in the evening?

no problem, which hour aprox?

20:30, 21:00 ?

A design that runs water off the top plane and maintains good airflow considering the thickness of the top plate would be ideal

off for now ... bbl
