LeSpirou:

This page lists and describes the purposes of the testpoints accessible on a 3DS's circuit board.

== Old 3DS ==

The signals were figured out using a PicoScope 2206B running at least at 2 MS/s, ±5 V, 8-bit, 1:10, DC. All measures of digital signals were referenced by the square GND pad at the bottom left corner.

And the TP to get Clock, Vertical-Sync and Horizontal-Sync.

== Captured Video Control Signals ==

The following picutres show plots of the control signals CLK (TP189), HSYNC (TP190) and VSYNC (TP191). The used sample rate were 50MHz.

The full plot shows about 2.6ms.

[[File:Stp_PCLK_VSYNC_HSYNC_full.jpg|1200px]]

This plot shows 1.28us, mainly featuring the clock

[[File:Stp_PCLK_VSYNC_HSYNC_0..64.jpg|1200px]]

Setup

The signal capturing was done by using an DE10-NANO FPGA development board, Intel signal tap analyzer and 5 wires soldered to the TPs of an EU-O3DS (roughly 25cm long, parallel wired).

VCD and CVS files:
[[Media: Stp_PCLK_VSYNC_HSYNC.7z]]
