Part Number: TPS929240-Q1

Tool/software:

I want to connect Led driver ckt to renesas RL/78 F24 microcontroller using uart communication. Can u provide information on which pin of led driver ckt should be connected to uart tx and rx of RL/78 F24. And information on how 24 led will be connected to the driver ckt if we can address 16 slave devices?

    Hello Pratish,

    I am not sure why you are asking us about how to connect the Renesas MCU to our device.  It is pretty simple.  The MCU UART Tx connects to our device's Rx and the MCU UART Rx connects to our Tx.  It looks like the Renesas part has two UART ports (UART0 and UART1).  It depends on which part you are using but the pin name uses TXD0, RXD0, TXD1, and RXD1 for the two UART buses.  You should confirm with Renesas.

    The answer to your second question about address, it is yes to 16 devices.  It is covered in the datasheet.

    Thanku for the reply but i am not able to understand how 16 device address will control 24 led channel. It should only operate 16 leds right? Or 16 device address means 16 led driver circuit connected connecting 16 * 24 = 384 led?

    Each device, which has a unique address, can control 24 channels.  That means you can theoretically control 384 LEDs if you use 16 devices, that have unique addresses, like you said.  I am not sure what you are confused about.
