Alex Lisitsyn 67f62a79c1 freemodbus: add modbus master ascii 
add support of modbus master ascii
rename base dir name of master and slave example to be mb_slave, mb_master to avoid conflict with sdio/slave example test
add Kconfig option to enable ASCII and RTU mode separately
update ASCII options + remove cast for errors
added baudrate for examples into Kconfig
updated magic numbers for timer timeout
put ascii private definitions into one file

menu "Modbus configuration"
config FMB_COMM_MODE_RTU_EN
bool "Enable Modbus stack support for RTU mode"
default y
help
Enable RTU Modbus communication mode option for Modbus serial stack.
config FMB_COMM_MODE_ASCII_EN
bool "Enable Modbus stack support for ASCII mode"
default y
help
Enable ASCII Modbus communication mode option for Modbus serial stack.
config FMB_MASTER_TIMEOUT_MS_RESPOND
int "Slave respond timeout (Milliseconds)"
default 150
range 50 400
help
If master sends a frame which is not broadcast, it has to wait sometime for slave response.
if slave is not respond in this time, the master will process timeout error.
config FMB_MASTER_DELAY_MS_CONVERT
int "Slave conversion delay (Milliseconds)"
default 200
range 50 400
help
If master sends a broadcast frame, it has to wait conversion time to delay,
then master can send next frame.
config FMB_QUEUE_LENGTH
int "Modbus serial task queue length"
range 0 200
default 20
help
Modbus serial driver queue length. It is used by event queue task.
See the serial driver API for more information.
config FMB_SERIAL_TASK_STACK_SIZE
int "Modbus serial task stack size"
range 768 8192
default 2048
help
Modbus serial task stack size for event queue task.
It may be adjusted when debugging is enabled (for example).
config FMB_SERIAL_BUF_SIZE
int "Modbus serial task RX/TX buffer size"
range 0 2048
default 256
help
Modbus serial task RX and TX buffer size for UART driver initialization.
This buffer is used for modbus frame transfer. The Modbus protocol maximum
frame size is 256 bytes. Bigger size can be used for non standard implementations.
config FMB_SERIAL_ASCII_BITS_PER_SYMB
int "Number of data bits per ASCII character"
default 8
range 7 8
depends on FMB_COMM_MODE_ASCII_EN
help
This option defines the number of data bits per ASCII character.
config FMB_SERIAL_ASCII_TIMEOUT_RESPOND_MS
int "Response timeout for ASCII communication mode (ms)"
default 1000
range 300 2000
depends on FMB_COMM_MODE_ASCII_EN
help
This option defines response timeout of slave in milliseconds for ASCII communication mode.
Thus the timeout will expire and allow the master’s program to handle the error.
config FMB_SERIAL_TASK_PRIO
int "Modbus serial task priority"
range 3 10
default 10
help
Modbus UART driver event task priority.
The priority of Modbus controller task is equal to (CONFIG_FMB_SERIAL_TASK_PRIO - 1).
config FMB_CONTROLLER_SLAVE_ID_SUPPORT
bool "Modbus controller slave ID support"
default n
help
Modbus slave ID support enable.
When enabled the Modbus <Report Slave ID> command is supported by stack.
config FMB_CONTROLLER_SLAVE_ID
hex "Modbus controller slave ID"
range 0 4294967295
default 0x00112233
depends on FMB_CONTROLLER_SLAVE_ID_SUPPORT
help
Modbus slave ID value to identify modbus device
in the network using <Report Slave ID> command.
Most significant byte of ID is used as short device ID and
other three bytes used as long ID.
config FMB_CONTROLLER_NOTIFY_TIMEOUT
int "Modbus controller notification timeout (ms)"
range 0 200
default 20
help
Modbus controller notification timeout in milliseconds.
This timeout is used to send notification about accessed parameters.
config FMB_CONTROLLER_NOTIFY_QUEUE_SIZE
int "Modbus controller notification queue size"
range 0 200
default 20
help
Modbus controller notification queue size.
The notification queue is used to get information about accessed parameters.
config FMB_CONTROLLER_STACK_SIZE
int "Modbus controller stack size"
range 0 8192
default 4096
help
Modbus controller task stack size. The Stack size may be adjusted when
debug mode is used which requires more stack size (for example).
config FMB_EVENT_QUEUE_TIMEOUT
int "Modbus stack event queue timeout (ms)"
range 0 500
default 20
help
Modbus stack event queue timeout in milliseconds. This may help to optimize
Modbus stack event processing time.
config FMB_TIMER_PORT_ENABLED
bool "Modbus slave stack use timer for 3.5T symbol time measurement"
default y
help
If this option is set the Modbus stack uses timer for T3.5 time measurement.
Else the internal UART TOUT timeout is used for 3.5T symbol time measurement.
config FMB_TIMER_GROUP
int "Modbus Timer group number"
range 0 1
default 0
help
Modbus Timer group number that is used for timeout measurement.
config FMB_TIMER_INDEX
int "Modbus Timer index in the group"
range 0 1
default 0
help
Modbus Timer Index in the group that is used for timeout measurement.
config FMB_TIMER_ISR_IN_IRAM
bool "Place timer interrupt handler into IRAM"
default n
select UART_ISR_IN_IRAM
help
This option places Modbus timer IRQ handler into IRAM.
This allows to avoid delays related to processing of non-IRAM-safe interrupts
during a flash write operation (NVS updating a value, or some other
flash API which has to perform an read/write operation and disable CPU cache).
This option has dependency with the UART_ISR_IN_IRAM option which places UART interrupt
handler into IRAM to prevent delays related to processing of UART events.
