Testing the board with a M5Stack
That's an ESP32, with a screen of 320x240.
For a 120us acquisition, that leaves 3us per pixel.. Still interesting to see. Moreover, there seems to be a 512KB RAM, would be enough to store long acquisitions. One line is 256kB at 64Msps.
Even a FFT processing would be possible.
Connectors necessary were :
- 5V
- GND
- CS
- MISO
- MOSI
Only SPI libs and M5Stack were necessary.. and a proof of concept was done with a single line acquisition process, for 200us, with a low gain.
