Hello fellas,
I am currently working on a MOODBUS protocol with UART interface to collect data from the slave device which is a sensor and send the data to Gateway master node.
UART interface: RS485 brakout board: Sparkfun, 8051 Micro-controller(ANU23600 1715G) by amicom.
I am new to the embedded programming and I currently have a two versions of customized code written in C per the project
Version:1: where the slave node is communicating to the gateway node (master) but not producing output, in the output I've connected the oscilloscope where I'm not getting any data output. I couldn't able to figure out why the slave node is not working.
The baud rate as 9600 bps.
Version:2: The slave is giving the output but not communicating to the gateway.
Could you guys please let me how to debug the program and make it work ?
Thanks in advance!
