Hello folks! Long time no see! :) In my previous post, we have discussed the basic concepts of PWM. It has a nicer profile. It works on the principle of Lorentz force by which the current carrying conductor in a magnetic field experiences a force hence the conductor moves on the direction of force called. PWM (William) 🇺🇸‏ @PWM62 Apr 19. Make the conversions, load the code, run the example on the MSP430 with the expansion board. It reduces complexity of the program. It presents basic concepts such as data representations (integer, fixed-point, floating-point), assembly instructions, stack, and implementing basic controls and functions of C language at the assembly level. In the C++ code given. Feel free to use the gpio program to configure other pins as input or output (PWM is only for special function pins like GPIO18(WiringPi 1), other PWM pins are occupied by the 3.
