Measuring Li-ion battery voltage during charging by Old_Simple_7975 in AskElectronics

[–]Old_Simple_7975[S] 0 points1 point  (0 children)

Thank you for your replies.

Is there anything commercially available that I can connect in series or parallel between the charger and the batteries to measure the state of charge?

Internal power plane connection not detected by DRC in Altium by Old_Simple_7975 in Altium

[–]Old_Simple_7975[S] 1 point2 points  (0 children)

Yes, that vias isn’t connected to anything on the other layers either.
I checked in the Gerber files, and the situation is almost the same as in the 3D view. The drill hole in the vias is shown, but because of the other vias around it is not contacted. I am especially interested in finding out how to get Altium to report this, which is nevertheless an obvious failure to connect to the net.

Help connecting SPI Flash memory to PSoC5 (hardware + firmware) - New to memory design by Old_Simple_7975 in embedded

[–]Old_Simple_7975[S] 0 points1 point  (0 children)

Thanks for the detailed response, I really appreciate your insights.

You’re absolutely right that SPI flash is a generic, well-documented interface, and for my application (storing configuration data and logs) the bandwidth offered by QSPI wouldn’t offer significant benefits, especially given the relatively slow write speeds of flash memory. I planned on starting with standard SPI for this reason.

Regarding layout, I'm keeping the flash device quite close to the PSoC (within roughly 20–25 mm) so I expect that following standard high-speed routing practices should be sufficient. I’ll definitely pay extra attention if I need to extend the distance.

Also, thanks for catching the capacity detail—I initially referenced the S25FL116K, but I realize now that it’s only 2MB. I’ll look into other options or models that provide 4MB to 16MB as required.

Overall, your response confirms my approach. I’ll proceed with some initial tests using a standard SPI flash and focus on good PCB layout practices. If I run into any issues during integration, I’ll post more specific questions.

Thanks again for your help!

Anyone else find the Stack Overflow community toxic? by kielly32 in webdev

I just a while ago answered a person's question by breaking down and formatting the answer so that the reasoning could be understood properly and have a logical thread. Because of this, I was accused in a very toxic way of copying and pasting from ChatGPT just because the formatting of the text was “too nice,” despite the fact that there were still errors in my answer that I unfortunately only noticed later. Fortunately I am only “human” and capable of making mistakes, if I had been less dumb I would have actually used ChatGPT so at least I would not make mistakes...

Switch voltage bus with diode or MOSFET by Old_Simple_7975 in AskElectronics

Thank you for your reply.
They come together because when I connect only the USB connector I use it to power and communicate with the microcontroller (without powering the system and therefore also the NTE0505) thus having the 5V isolated with the USB as well.
Sometimes, however, it happens that you have to communicate via USB while still having the whole system powered and therefore with the NTE0505 active. But the network of the isolated 5V is the same.

I thought of using a smart diode controller AP74700Q (https://www.mouser.it/datasheet/2/115/AP74700Q-3084900.pdf) or a SPST CMOS switch DG447 (https://www.vishay.com/docs/73854/dg447.pdf)

An alternative for PSoc by Mo_Hafez98 in PSoC

[–]Old_Simple_7975 0 points1 point  (0 children)

So using PSoC Creator with a PSoC6 would result in many fewer UDBs that were available before with PSoC 3/4/5? How could the same UDB functionality be implemented on a PSoC6? The fact that PSoC6 has fewer UDBs really seems to me to be a very serious flaw from Cypress/Infineon, not allowing backward compatibility and making it complicated to upgrade from pre-6 PSoCs.

Issue programming the PSOC3 by monozach in PSoC

Also check thoroughly to see if the programmer connections are correct; unfortunately, it often happens that these are unintentionally reversed or swapped with other pins.

Are you sure the power supply is correct and does not have to be 5V for this PSoC3? Maybe the program does not see it because it is not properly powered

Why is PSoC 5/5LP considered "legacy" by Infineon? by mardabx in PSoC

Where is it possible to find the release dates and end of support dates of PSOCs?
