## LED Connections

|  FPGA Pin (J8)  | FPGA Function | OLED Pin | Bus Pirate | Function | Description |
|-----------------|---------------|----------|------------|----------|-------------|
| 1 (Red) (133)        |    tm1637_vcc           | VCC         | 3.3V | 3.3 to 5.0 volts | Supply voltage (up to ?? mA) - `IO_TYPE=LVCMOS33 DRIVE=24 BANK_VCCIO=3.3;` |
| 2 (Black)       |               | GND         | GND  | Ground           | Common return path |
| 3 (Green) (131)      | tm1637_clk_drain       | CLK  | CLK |    |  Open Drain with Pull-Up Resistors - `IO_TYPE=LVCMOS33 DRIVE=24 OPEN_DRAIN=ON BANK_VCCIO=3.3;` |
| 4 (Yellow) (132)      | tm1637_dio_drain      | DIO  | MOSI  |          |  Open Drain with Pull-Up Resistors - `IO_TYPE=LVCMOS33 DRIVE=24 OPEN_DRAIN=ON BANK_VCCIO=3.3;`  |

## FPGA Power

>Input DC5V power supply via USB port or socket. Input via socket if the
SW1 switch is pressed; input via USB port if the SW1 switch pops up.

## Internal Flash

>1. SRAM:
Scan the device and download the bit file after powering the device on.
The Done indicator lights up to denote that the download has been
successful.
Note!
The mode is independent of the values of MODE0 and MODE1.
>2. Internal Flash:
Power on to download. After downloading the data stream file
successfully, power down to reset and load the bit file from the internal
Flash, and when the Done indicator lights up to denote that the download
has been successful.
Note!
Before downloading the bit file, MODE0 and MODE1 need to set to
"00".
