The ECUAL driver for the servo motor for example will check its configuration file to know which timer is assigned to it by the user (the application programmer) and therefore, initialize this timer and do its work. So the application code doesnР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›t talk directly to TIMER1 or USART3 or whatever. Anything on the ECU level that supports the functionality of the MCU in the embedded system shall go into this layer.Р В РІР‚СњР В РІР‚С›n ECUAL driver is basically a set of functions that initialized the MCU HW via the HAL and does the calling of HAL functions, necessary calculations, algorithms, and utilities, in order to abstract the hardware handling from the application layer.

The hardware drivers which interface the microcontroller to the outside world of sensors, IO units, displays, memories, and so on. WeР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll introduce a new layer called ECU Abstraction Layer (ECUAL) where weР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll populate our external drivers. So, itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s OK!Р В РІР‚СњР В РІР‚С›dding ECUAL Layer To The Software Layered Architecture

This will make it a little bit more complicated, and it should, but in the name of making our applications more portable and easily configurable.

And thatР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s why weР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re going to make a small change to it. There are a lot of examples where this simple way of architecting the software would fail and be painful to port or configure. This significantly reduces the application code portability across multiple platforms and even introduces the possibility of clashes on the same target MCU itself (like a servo motor being hooked to TIMER2 CH1 meanwhile ultrasonic driver is hooked to the same hardware TIMER). YouР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›ll end up with an application code that is tied up to the underlying HAL drivers (like a servo motor that is hooked to TIMER2, or whatever). However, proceeding with this setting will result in more problems in the future. There were no issues in this and you can justify this by saying its a simple architecture and looks clear enough. The Previous Software Layered Architecture As you can see the application layer is built upon the HAL and LL drivers from STMicroelectronics. The software architecture weР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re sticking to was this one in the diagram below. Now, after 20 tutorials in this series, I think itР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›s time to make a small change in the way weР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС›re writing applicationsР В Р вЂ Р В РІР‚С™Р Р†РІР‚С›РЎС› code.
