check master read write functions with array of registers) fix master serial processing code and modbus controller to work with register array modbus_master: add reading and writing of test value array (58 registers) to check failure is gone remove parameter temporary buffer from modbus controller to allow more than 24 byte writes driver: fix issue with TOUT feature driver: fix uart_rx_timeout issue driver: fix issue with rxfifo_tout_int_raw not triggered when received fifo_len = 120 byte and all bytes read out of fifo as result of rxfifo_full_int_raw driver: add function uart_internal_set_always_rx_timeout() to always handle tout interrupt examples: call uart_internal_set_always_rx_timeout() to handle tout interrupt correctly examples: update examples to use tout feature driver: reflect changes of uart_set_always_rx_timeout() function, change uart.c driver: change conditions to trigger workaround for tout feature in uart.c driver: change uart_set_always_rx_timeout() freemodbus: fix tabs, remove commented code driver: remove uart_ll_is_rx_idle() |

HAL Layer Readme
The HAL layer is designed to be used by the drivers. We don't guarantee the stability and back-compatibility among versions. The HAL layer may update very frequently with the driver. Please don't use them in the applications or treat them as stable APIs.
The HAL layer consists of two layers: HAL (upper) and Lowlevel(bottom). The HAL layer defines the steps and data required by the peripheral. The lowlevel is a translation layer converting general conceptions to register configurations.
Lowlevel
This layer should be all static inline. The first argument of LL functions is usually a pointer to the beginning address of the peripheral register. Each chip should have its own LL layer. The functions in this layer should be atomic and independent from each other so that the upper layer can change/perform one of the options/operation without touching the others.
HAL
This layer should depend on the operating system as little as possible. It's a wrapping of LL functions, so that the upper layer can combine basic steps into different working ways (polling, non-polling, interrupt, etc.). Without using queues/locks/delay/loop/etc., this layer can be easily port to other os or simulation systems.
To get better performance and better porting ability, contexts are used to hold sustainable data and pass the parameters.
To develop your own driver, it is suggested to copy the HAL layer to your own code and keep them until manual update.
