3 / 15 page www.ti.com Jumpers Connections Press keys SW2 and SW3 simultaneously Start GUI software on computer 3. Variable Gain mode Connect pins 2 and 3 of jumper J6. Connect pins 1 and 2 of jumper J7. Attach a signal generator to the EXT_IN connector (SMA or SMB connector may need to be populated). Press keys SW2 and SW3 simultaneously Start GUI software on computer Connect the LaunchPad and TPL0501EVM to a computer through the USB connector 4 Jumpers Connections 1. J1 & J2 – LaunchPad Headers These connectors mate with the male headers on the LaunchPad 2. J3 – External LED Power This connector is where the external +5V supply is attached to power the two RGB LEDs. 3. J4 – TCA7408 GPIO This is a pin out of the four unused GPIO pins from the TCA7408, GPIO4-GPIO7. 4. J5 – Feedback loop For the TPL0401A to function as a voltage reference circuit the negative feedback loop must be shorted, placing a jumper across this header will short the inverting input to the output. 5. J6 – LED or Op-amp This header controls what the TPL0401B is attached to. When shorted across position 1 and 2 the TPL0401B is connected in series with the external resistor to control the current through the LED driver. When shorted across position 2 and 3 the TPL0401B is connected to the inverting input of the op-amp to change the gain of the circuit. 6. J7 – Op-amp input This header controls the input to the non-inverting pin of the LMV321. When shorted across position 1 and 2, the TPL0401A in a voltage divider mode is attached to the non-inverting input of the LVM321. This setup is used to test the voltage reference setup. When shorted across pins 2 and 3, the SMA connector is attached to the non-inverting input. 7. J9 – Test Points This connector offers test points for the serial data lines, SDA, SCL and the DIN that drives the TCA5405 Table 1. Description of Connectors and Jumpers Label Description J1, J2 Connectors to interface with LaunchPad J3 External 5V for LED J4 GPIO4-GPIO7 from TCA7408 J5 Control jumper to short feedback loop J6 Jumper to control LED or Op-Amp J7 Jumper to control input to Op-Amp J8 SMA/B Footprint for external input J9 Test points for DIN, SDA and SCL 5 Software Setup The EVM does not require any software set up to operate in the LED mode. The keys SW1-SW4 control the blinking rate of the LEDs and the color mixing of the LEDs, without any additional software setup. To operate the EVM in any other mode, GUI software is required. The GUI software is available in a zip 3 SLIU008 – September 2011 TPL0401EVM Submit Documentation Feedback Copyright © 2011, Texas Instruments Incorporated |
