Next: Getting started with RKH

Each RKH application must have its own configuration file, called rkhcfg.h. This file adapts and configures RKH by means of compiler definitions and macros allowing to restrict the resources consumed by RKH. Adjusting this definitions allows to reduce the ROM and RAM consumption, and to enhance the system performance in a substantial manner.

Also, each RKH port must have its own configuration options, that must be explicitely defined in the proper rkhport.h file. Here is an list of all options with their documentation:

When this is set the application must provide the hook function.
RKH_CFG_FWK_TICK_RATE_HZ integer [1..1000] 100 Specify the frequency of the framework tick interrupt (number of ticks in one second). It's the rate at which the rkh_tmr_tick() function is invoked. This configuration constant is not used by RKH, it is just a value to allow an application to deal with time when using timer services, converting ticks to time. See RKH_TICK_RATE_MS constant.
RKH_CFG_FWK_AWARE_ISR_PRIO integer [0..255] 0 This number divides interrupts into "aware" and "unware" interrupts, which are never disabled, and "aware" interrupts, which are disabled in the RKH critical section. For example, an interrupt priority number lower than RKH_CFG_FWK_AWARE_ISR_PRIO indicates an "unware" interrupt, whereas an interrupt priority number equal or higher than RKH_CFG_FWK_AWARE_ISR_PRIO indicates an "aware" interrupt.

RKH_CFG_SMA_SM_CONST_EN boolean RKH_ENABLED If RKH_CFG_SMA_SM_CONST_EN is set to RKH_ENABLED then much of the state machine object is allocated in ROM. This approach does have as key benefit the little RAM consuming as compared when RKH_CFG_SMA_SM_CONST_EN is set to RKH_DISABLED. Nevertheless, the primary drawback of this approach is the obfuscated API to use it. In constrast, if RKH_CFG_SMA_SM_CONST_EN is set to RKH_ENABLED then the whole state machine object is allocated in RAM, including its own constant part. However, the API to use it is very simple, intuitive, and flexible, allowing easily the dynamic memory allocation.

RKH_CFG_TMR_EN boolean RKH_ENABLED If the RKH_CFG_QUE_EN is set to 1 then RKH will include the native software timer facility.
RKH_CFG_TMR_SIZEOF_NTIMER integer [8,16,32] 8 Specify the dynamic range of the time delays measured in clock ticks (maximum number of ticks). The valid values [in bits] are 8, 16 or 32. Default is 8.
RKH_CFG_TMR_HOOK_EN boolean RKH_DISABLED If the RKH_CFG_TMR_HOOK_EN is set to 1 then RKH will invoke a hook function when a timer expires. When this is set the application must provide the hook function.
RKH_CFG_TMR_GET_INFO_EN boolean RKH_DISABLED If the RKH_CFG_TMR_GET_INFO_EN is set to 1 then RKH will include the rkh_tmr_get_info() function that retrieves performance information for a particular software timer. See rkh_tmr_get_info() function.
