Hi all
I am using st7540 with its default setting and connecting it to a microcontroller. I send data on TXD line of st7540 at 2400 baud rate but i am unable to detect carrier frequency at TX_out line,
I have connected UART/SPI to 1 and RxTx to 0, already followed the datasheet to setup and spent so much time trying many different connections.
Does anyone know how to make this chip work??
Any help would be greatly appreciated!
