* removed (rmmod) various kernel modules to completely disable devices, like wifi and bluetooth if you use both dtoverlay=disable-wifi and dtoverlay=disable-bt, then you will get a measurable drop in power usage no need to remove any modules * Tried turning off some PCI devices that powertop was reporting as 100% active, until the board froze a number of the pci drivers dont take unloading well, its better to disable things in DT and make them never load in the first place if you dont need gpio/ethernet/dsi/csi/fan, then you could disable the entire RP1 and keep it in reset, that might ..read more

I'm sure there is some horribly written software out there for these modules, but not all of it can be horribly bad. Meaning, you probably already ran into the simpler versions of that code out there and could not understand it. Which leaves practicing and becoming a more knowledgeable and proficient programmer, so you can understand that simpler code. Am I right to assume that is something you are not willing to do? Because if I am right,.I have bad news. Leaning and getting better at it sometimes is really the only option (other than someone else doing it for you either for free or for a c ..read more

I'm not interested in using a bigger cooler, but to have the Pi5 consuming less amount energy than the usual ~1.5W to 2W it is said to consume. Well, why didn't you say so to begin with? That's easy to accomplish. Just keep it disconnected from power. The reason it does not behave like a phone is because it does not have all the power management cell ones do. It was not designed for that. Statistics: Posted by memjr — Mon Apr 29, 2024 1:54 am ..read more

Exactly the same information with a different IP address (192.168.1.128). My DHCP pool starts at .110. Other than a different, valid, IP address, I can't find anything different! (And there is no chance of a duplicate.) Statistics: Posted by ka2irq — Mon Apr 29, 2024 1:09 am ..read more

One detail about most of these character displays: they need to be powered from 5 V. If you power them from 3.3 V, it's likely that the backlight won't work. They typically work with 3.3 V logic, but 5 V power. A very few of them are 3.3 V power and logic. They're usually labelled as such. I do recommend the i2c adapter type, typically a PCF8574 chip. I haven't used any C libraries with these, but here's one that might work: gavinlyonsrepo/HD44780_LCD_PCF8574_PICO: Library to support the HD44780 LCD , (I2C PCF8574 "backpack" interface) for the RPI PICO RP2040 C++ SDK Statistics: Posted by sc ..read more

When increasing the number of active cores, does the N100 miniPC show a similar drop in aggregate memory bandwidth? I'm afraid the N100 has been loaded with Windows and is no longer available with Linux. Oh well. Since the N100 has only one channel of DDR5 memory, I wondered what would happen. The exalted one has allowed me to steal 32GB from her SSD to install Ubuntu, under penalty of starving to death should I mess up her computer.

Hi B.Goode My two pi 5's are connect through ethernet cable via a switch, but I am using a TP link for my switch, it's not directly connected to my router. My iMac is connected through the wifi The two IP address that I have for the pi's are 192.168.1.231 and 192.168.1.130 I am not sure how to verify if my network imposes client isolation. My internet service provider gives access to the router via a GUI and I have tried to find anything network isolation related.
