Part Number: TMS570LC4357

Hello,

i have a little problem with understanding the Port and Pins of this board.

Do i have 'Ports' on this Board? Or is every Module like ADC a own Port.

For Example i have 32 Pins :

How can i access to those Pins ? On my board there are names like J10 J9 and so on.

I Know that Pin 6 is my Temp Sensor on the board, because i have read it directly from the board. But for example i want to enable Pin 2. Where can i connect my sensor on?

Thank you

Hello,

The ADC pins are mapped onto J9 connector of HDK. HDK uses AD1IN8 for temperature sensor, and AD1IN9 for light sensor. Actually you can use any other ADC pin (on J9) for your sensor.

1. Populate resistor (R1) and capacitor (C12) on HDK for Pin2
2. Add a voltage divider to make sure the input to ADCIN pin is in the valid range

On this sheet, the ADC1In[2] is on V17. Where can i find V17 ? What is the difference between V17 and J9 ? Is it just the location?

Thanks a lot

Hello,

V17 is the pin number of AD1IN1. You are right, it is the location of AD1IN1.

J9, do you mean the connector J9 on HDK? or the pin number (J9, VSS) of LC4357 device?
