Hello Francois, some addtl. thoughts: 1. I think SPEED of the simulator is one of the major requirements to simulate the engine at higher RPMs. With 4MHz clock and 0.5us smallest timer period the CC1 is not very fast. 2. The CC1 has already an OS implemented in ROM (which is an intepreter) the SPEED of the program code is also limited. The user can access 255Bytes of uC internal EEPROM to run machine code. I think these 255Bytes will not be enough to make the desired application. Kind regards, MaPi >Hello Francois, > I think the signals you like to simulate are mixed signals, means some of them are digital (like crankshaft and camshaft signal) and some of them are analog (like throttle angle and engine temperature). > Possibly you have to specify the signals before somebody can decide if CC1 is appropriate for this purpose. > With CC1 you have 16 digital in/outputs available, which can also be changed in kHz range (when applying Assembler code), 8 ADC inputs but only 2 DA (PWM) outputs with limited update frequency. > All signals are in the range of 0...5V. > > In general I would say: Yes, with CC1 you could do some engine signal simulation (with limitation and possibly addtl HW effort).
