I just remembered... the OMAP5432 CPU in the Pyra contains (same as with the AM335x) two fully-programmable Cortex M4 microcontrollers: https://pyra-handheld.com/boards/threads/arm-m4-usage.82072/
I wonder if they're able to handle polling of the volume wheel ADC in the background... and then...
Exactly what kind of parts are affected by the shortages? The CPU or RAM? Or is it trivial stuff like SMD capacitors?
I would be interested to know this, once you know this yourself. Thanks!
Then please, next time, describe in your post what the code does! Don't assume we can all immediately see that from reading the code.
Can you be more specific? It sucked because it was too slow to respond to changes? Because it made the code unnecessarily complex? Because it used too much CPU...
It's important to note that the poti has end stops (it can only turns some limited amount in each direction). An advantage is, at suspend/resume, or a reboot, the poti remembers its absolute position. And you can feel with your fingers when you've reached the minimum/maximum.
A disadvantage is...
If U-Boot could detect this situation, it could boot an alternate system that goes into a low-power mode (turn off display or peripherals), indicates the level of charge somehow (e.g. with LEDs, or on-screen after a button press) and upon pressing the power button, reboots into the real OS.
Most...
If Audacity is working already on the Pyra that would be another good way to test audio.
Would be also interesting to play a sine wave from the left speaker at the same time as the *inverted* signal from the right speaker.
If both channels are played correctly, you would notice weird phase...
There are definitely a lot of people interested in running decentralized/federated services like blogs, chat, email, OwnCloud on their own hardware.
If your cell plan doesn't include an IPv4 address (most don't), then you may need to rent one somehow and set up a VPN tunnel so that the...
Generate QR codes on the screen, read them with a webcam/smartphone which saves them to a file (or even stops/pauses the test when no code has been read for X seconds)?
* include a counter or timer in the QR code
* reduce the number of error correction blocks when generating the QR code
*...
Successfully tested the Pyra's Wi-Fi at DebConf17. It worked, showed good speeds, but signal strength dropped off sharply with distance from the access point. It seems like, the transmit or receive SNR is worse than it should be.
