mithroayush3504: ping?01:11
*** mparuszewski has quit IRC01:12
mithroayush3504: give me a moment and then we need to go through some stuff01:18
ayush3504mithro: sure01:27
mithroayush3504: okay, I'm around now - where are you at with everything?02:49
ayush3504mithro: a few remaining daughterboard schematics, need to explain a diagram and adding power calculation spreadsheet in requirements document02:51
ayush3504mithro: also PIC18 USB sheet needs some work02:51
ayush3504mithro: the bus pins method doesn't seem to work. See my reply in the github issue02:52
ayush3504mithro: need to know where the SPI pins go into the VHDCI with only two remaining pins02:53
mithroayush3504: the VHDCI pin mapping should be included in a spreadsheet somewhere?02:55
ayush3504mithro: yes, will do after all pins get decided, as of now it's easy to understand 6 x RX,TX,RTS,CTS,DTR,DSR + SDA, SCL - 38 pins02:56
ayush3504mithro: =02:56
mithroayush3504: sure, that information should be in the same spreadsheet I think02:57
ayush3504mithro: we have a spreadsheet for that already if you remember02:57
mithroayush3504: sure, which one?02:58
ayush3504mithro: the Pin Usage sheet?02:59
mithroThe "Atlys Expansion Boards Information (using VHDCI connectors)" spreadsheet is really for after the design is published / finished03:01
mithroIt is a "documentation spreadsheet" rather than a "design spreadsheet"03:01
mithroA design spreadsheet is suppose to make it easier for you to design your system03:04
ayush3504mithro: okay03:05
mithrowhere is the motherboard mechanical spreadsheet again?03:06
ayush3504mithro: i'll make a separate. for now you can take a look at it, i have updated it.03:06
tpbTitle: Serial expansion board and daughterboard design - Google Tabellen (at
ayush3504mithro: brb power gone03:09
mithroayush3504: it looks like your BUS make up is totally foobar03:16
mithroayush3504: poke me when you are back03:55
ayush3504mithro: back04:13
mithroayush3504: this schematic still needs a bunch of work04:14
ayush3504mithro: for the daughterboards, you were looking at templates, only two were done04:15
mithroCan you make sure you have pushed everything?04:16

ayush3504mithro: bus thing wasn't working so i didn't push. that's why i sent photos04:17
ayush3504mithro: neither commited04:17
mithroayush3504: okay04:18
mithroayush3504: I think you should have a separate sheet which is shared between all the daughterboards for the "stand alone" parts (IE the input DB9 and the level shifter)04:19
ayush3504mithro:yes, except for GPIO8 and RS232 boards that have been done04:20
ayush3504mithro: also the IR04:20
mithroayush3504: so what should I be looking at then?04:20
ayush3504mithro: because most things are common i made a template04:20
ayush3504mithro: gpio8, rs232, IR04:20
ayush3504mithro: my commit history would tell you these things :)04:21
mithroI'm looking at the GPIO-8 and not quite able to understand what is going on04:22
mithroThe EEPROM is on the GPIO-8 standalone sheet?04:23
ayush3504i have making a component so i can't check at the moment. but the EEPROM is on the main sheet04:24
ayush3504mithro: the standalone sheet can be imported as a hierarchical sheet in the motherboard schematic if a preloaded PCB is needed04:25
ayush3504mithro: sorry, eeprom is on standalone sheet04:26
ayush3504mithro: so if you use this sheet with motherboard schematic, it will be there, but you always have an option of not populating it on pcb04:26
mithroThe RS232C has two ISL83387E chips on it? Why04:26
ayush3504 mithro: ah, didn't notice it doesn't make sense. will remove it.. It's useful for all other boards though04:27
ayush3504mithro: i mean the left chip04:27
mithroayush3504: so I think you need to reorganise all these daughterboards and make liberal use of symbolic links04:28
mithroThe EEPROM is the same for every daughterboard right?04:29
ayush3504mithro: yes04:29
mithrocreate a "common" directory04:29
mithroput the schematic for the EEPROM in it04:29
mithrothen symlink it into the other directories04:29
mithroif that works, then you only need the sheet once04:30
mithrodo the same for the "input side" of the daughterboard04:30
ayush3504mithro: i did that for PIC16F GPIO, but it didn't look useful for eeprom04:30
ayush3504mithro: ok04:32

aps-sidsmithro: CarlFK:  I've not been able to fix the problem(s) with with overlay component and I have decided to port some other components first. Do we have any preferred components?06:44
