* Dec 2023, Added NXP SC16IS752 I2C Dual UART
|
||||
* The SC16IS752 has 64 bytes TX & RX FIFO buffer
|
||||
* First version without interrupts from I2C UART and only RX/TX are used, interrupts may not be
|
||||
* needed as the RX Fifo holds the reply
|
||||
*
|
||||
* Jan 2024, Issue with using both UARTs simultaniously, the secod uart seems to work but the first transmit
|
||||
* corrupt data. This need more analysis and experimenatation.
|
||||
* Will push this driver to the dev branch with the uart fixed to 0
|
||||
* Both SC16IS750 (single uart) and SC16IS752 (dual uart, but only uart 0 is enable)
