Hi Stan! so glad to see i’m not the last one over here.
Thanks for the bumps.
So… since you are here, do you mind if i ask you a few questions on the design?
The development reached a point where i have to make some decisions and since you are far more experienced than me, your knowledge can be very valuable.
I have the idea of using a PSRam over QSPI to buffer the frame and then read the same PSRam with another uC, i have an ESP32 laying around that i can hook to the same QSPI bus and make it dump all the RAM content to an SD.
Ideally speaking i should send the data to the uC and make it buffer then save on its own but the ESP32 has this specific type i/o (i2c, i2s, spi, etc.) that needs some heavy knowledge on the guts to allow the code to DMA all that mixed ports data in some usable way to read a fast parallel 8 bit sample.
Choosing another uC is a viable choice too but since i’m in argentina my only choices are the ESP i have, the most basic STM32, some arduino with atmega328 or maybe a raspberry pico.
Anyway, so glad to see someone else.
thanks for your comment, any help is really appreciated!
