Hi to all
I'm doing RS-485 on K60 uP for using KSDK 1.1.0 (working on KDS 2.0.0)
On K20 without KSDK I use LDD uart component where is present TX-Complete-Callback, so here I can set "Receiving" the direction for RS485 converter
In KSDK I use this component: fsl_uart
Now there is not any callback on TX (from KDSK 1.0.0 to KDSK 1.1.0 were available RX callback, very usefull, but nothing about TX callback).
I try to set the "Install Interrupt" and I see the Interrupt RX and TX but, analyzing inside IRQ, there is only present the call at this HAL:
UART_HAL_IsTxDataRegEmpty
that tell me when tx data register is empty so we can put another byte in the buffer... but what I need is that hal:
UART_HAL_IsTxComplete(baseAddr))
that tell me WHEN ALL BYTE WERE SEND. this function hal was called only on deinit function.
So I can't wait (I'm using FreeRTOS) in a loop the return of UART_HAL_IsTxComplete set to one... for the same reason I can't do a several of wait of FreeRTOS and check the UART_HAL_IsTxComplete (maybe RX started when i'm still waiting... and direction bit is still on tx)
what I need is ( LIKE THE LDD COMPONENT ) a callback for the interrupt of TX-complete.
Or I need the active interrupt (on IRQ internal handler of processor expert) for TX-complete.
What I can do with processor expert? If is not possible to install this interrupt handler or callback with processor expert, what I can do "manually" ?
Many thanks
