2023-01-18: The ice40-usbtrace OSHW USB protocol tracer

Added by laforge 11 days ago

we're happy to announce the next incarnation of OsmoDevCall.

This time, tnt will be presenting on the ice40-usbtrace OSHW USB protocol tracer

In case you never heard about ice40-usbtrace before: It's a low-cost full-speed USB protocol tracer built around the iCE40 FPGA (git repo).

When: Wednesday, January 18, 2023 from 20:00 CET

2022-12-21: USB hub for device testing

Added by laforge about 1 month ago

we're happy to announce the next incarnation of OsmoDevCall.

This time, tsaitgaist will be presenting on USB hub for device testing.

When: Wednesday, December 21, 2022 from 20:00 CET

Abstract:

During hardware development and testing you often have numerous additional devices attached to it: serial debugger, programmer, logic analyzer, and so on.
A commercial USB hub should be enough handle that, but it often comes with limitations.
So why not have a USB hub designed for assisting in hardware development and testing: flat 7 ports, impedance controlled, with current and ESD protection, and remote power control for USB and higher voltages.
The result is open source and available at https://git.cuvoodoo.info/usb_hub.

2022-11-16: MS/BS power control support in OsmoBSC/OsmoBTS

Added by laforge 2 months ago

we're happy to announce the next incarnation of OsmoDevCall. Based on the recent polls, the timing has shifted to every 3rd wednesday of the month.

This time, fixeria will be presenting on MS/BS power control support in OsmoBSC/OsmoBTS.

For those not entirely 3gpp-acronym-savyy: That's how the uplink (phone -> network) and downlink (network -> phone) transmit RF power level is adjusted during an active call in GSM.

2022-02-25: Advanced SIM topics: SCP02, OTA, ARA-M, ISIM

Added by laforge 11 months ago

We're happy to announce the next incarnation of OsmoDevCall

This time, laforge will be presenting on Advanced SIM card topics: GlobalPlatform SCP02, OTA, ARA-M, ISIM

The talk covers some of the more advanced topics related to SIM cards:
  • GlobalPlatform commands / SCP02 protocol
  • OTA (Over The Air) RFM/RAM via TS 03.34
  • The ARA-M applet
  • The ISIM application

It is expected that the audience is familiar with SIM card basics, such as SIM/UICC/USIM concepts and the general file system abstraction.

2022-01-28 : Various short [mostly retronetworking] talks

Added by laforge about 1 year ago

We're happy to announce the 22nd incarnation of OsmoDevCall

In this edition, laforge will present a number of brief (lightning) talks about a number of projects he's currently been thinking about or working on, including
  • efficient TDMoIP protocol
  • TDMoIP community network
  • hardware design of ISDN BRI interface for TDMoIP community network
  • continuous testing setup for simtrace2 "cardem" firmware
  • non-transparent ISA-over-USB bridge attached to qemu

The idea is to ping-pong some ideas wit others and maybe find somebody interested in helping out.

When: Friday, January 28, 2022 from 20:00 CET

Time Topic Who
20:00 Meet and Greet everyone
