Glasgow revC devices use 74LVC1T45 level shifters for the two ports. They support a 1.65 to 5.5 V voltage range, but lack official support for 1.2 V. @attie found out...
A list of everything that should be decided and/or done for revC3 of the Glasgow hardware. - [x] Finish qualification tests for revC2 ( #220 #221 ) - [x] Fix...
Without this, the DAC still outputs it's control voltage even if Vio is off. This goes through the feedback resistors to the output. I measured about 15 mV without this...
These commits bring the firmware for revC2 to the same level as revC1. This means you can read voltages, set alert levels, read alert levels, read alert status. Also alerts...
I wanted to further verify the test jig board works. Although I know that this applet can't be used to control the test jig in production (as that will be...
Selftest can give false-positive results on revC, see for example https://twitter.com/szeloof/status/1161346534098833408 The main reason is probably that cmos inputs are left floating in high-z and their value is used for...
This is to make cable issues or charge-only usb cables easily visible for the user. Use a slow blink (not aggressively fast) because this could also be a permanent and...
The Glasgow archive is designed to store older versions of relevant documentation for devices or standards, even when the vendor removes them or redacts out important information. Currently the archive...
Steps to reproduce 1. flash firmware or gateware onto the eeproms 2. short the recover jumper and release reset 3. ```glasgow factory --force --rev C2``` Result: ``` W: g.device.hardware: device...
revC2 replaces the ADC081C021, which was used on previous revisions, with the INA233. The firmware needs to be adapted to communicate with the INA233 on revC2 boards. First step is...
