The tlc5620 protocol decoder decodes the Texas Instruments TLC5620 (8-bit quad DAC) protocol.
Hardware
TLC5620 in the Velleman PCSU1000
The dac/ti_tlc5620 directory in sigrok-dumps contains a set of example captures of a TLC5620 signal grabbed from a running Velleman PCSU1000 USB oscilloscope.
The logic analyzer used was a Saleae Logic (at 2MHz).
Probe setup:
| Probe | TLC5620 pin |
|---|---|
| 1 (black) | DATA |
| 2 (brown) | CLK |
| 3 (red) | LOAD |
| 4 (orange) | LDAC |
Protocol
TODO.
