Hi,


My goal is to get an modbus Server running with an RS485 Uart on a MK10FN1M0VLQ12. So far I haven't found a suitable driver or newb example to get started on the low level stuff. Any Ideas for where to find Driver example for mk10?

If I where to setup this from scratch and I want to set the pheripheral driver to handle silent interval max and min in characters (1 ch = 10 bit with stop bit) and clear to send intervall.

silent intervall

- If there is an space inbetween >1,5ch(min) and <3,5ch(max) the serial driver shall discard the incomming buffer.

- If the silent space is >3,5ch the incomming buffer shall be handled by the modbus rtu driver.

- If silent space is >4,5 outgoing buffer can be sent.

What would be the proper solution, timer baud polled IO and/or with interrupt and/ with DMA?

thanks!

regards

Andreas

Although we don't offer a free library to implement Modbus, there are third party options, I suggest you check the following thread:

Is there any library for modbus?
