Hardware Design Considerations for an Electric Bicycle using BLDC Motor
Texas InstrumentsA traditional bicycle is a two-wheel vehicle that is propelled by the rider who delivers muscle power through pedals that rotate one of the two wheels. The rider steers the front wheel to create a force that returns and maintains the vehicle center of gravity into a stable zone whenever necessary, thus keeping the bicycle upright. An electric bicycle carries batteries that deliver electric power to a motor that is coupled to either wheel. In most electric bicycles the rider can chose to use muscle power to deliver all, part, or none of the propulsion power required to maintain an adopted travel speed. Some models even sense pedal pressure and command the motor to deliver more power whenever the rider pedals harder.

Texas InstrumentsThis application report provides a summary of the differences between the TMS570LS04x/03x versus the TMS570LS31x/21x and TMS570LA12x/11x series of microcontrollers.
Field Oriented Control 3-Phase AC-Motors
Texas InstrumentsThe principle of vector control of electrical drives is based on the control of both the magnitude and the phase of each phase current and voltage. For as long as this type of control considers the three phase system as three independent systems the control will remain analog and thus present several drawbacks. Since high computational power silicon devices such as the TMS320F240 from TI came to

Online Stack Overflow Detection on the TMS320C28x DSP
Texas InstrumentsA stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption lost return addresses or both. Traditional off-line approaches to sizing a stack during development such as filling with a know value or estimating based on code content are not 100% reliable. Therefore programmers often feel compelled to reserve larger stack sizes than are
