Jan 31, 2024 · You need to apply voltage gain so that dV/dt out is over 5 times the 'leading edge' of the STM32. drive signal. A fast NPN transistor, with R//C emitter load, possibly in cascode with a higher voltage. drive transistor, can give you a fast output fall-time, and Baker-clamping the base to collector can get you.
Feb 15, 2004 · If you can post your source and dsn file we'll have a look. Typically this happens when you externally wire a crystal etc. - this introduces an extremely high speed oscillator which bottlenecks the simulation and is completely superfluous anyway. Clock frequency is specified as a property of the microcontroller device.
Apr 30, 2019 · The principle is: 1. wait for zero crossing, 2. wait a time determined by how much power (= motor speed) you need. 3. trigger the SCR. 4. go back to step 1. The difference between minimum power and maximum power is the time taken by one AC cycle so it will typically be 20mS for 50Hz mains and 16.6mS for 60Hz mains.
Feb 19, 2015 · 3. Does the speed need regulating and if so, how is the feedback achieved. 4. Does the control circuit have to be isolated from the power source. answering 1 - 4 will give an idea of how the speed can be controlled. 5. what remote control coding system is used. 6. does it use IR, ultrasonic or wireless. If wireless does it use a LAN or other ...
Mar 14, 2006 · 1,298. Activity points. 7,491. Re: SPEED GRADE. The lower the -X the faster the FPGA. The speed is specified in terms of the tpd (pin-to-pin delay) parameter in the FPGA datasheet. This affects the maximum operating frequency of your design in that particular FPGA. Jun 26, 2006. #3.
Aug 21, 2010 · Hi Dinesh, First of which servo motor you are using .....if it is stepper motor....as stepper motor is one type of servo motor. There are two ways at least I know by which you can control the speed of the stepper motor. 1) After every step in the servo motor control .....there is dealy between the steps .....if you control or change that dealy ...
Aug 3, 2007 · 1,302. I would like to maintain the speed of 3-6V toy train. that is, the speed of a straight. path should be maintained along a circular path (the train has a slower speed in. circular track) and when the train is started in a circular path, it has the speed of the. straight path. the circuit I require more probably maintain the output voltage ...
1,298. Location. IRAN. Activity points. 2,374. Hi. I decide to use FT245RL from FTDI to transfer about 500 MB from PC to a embedded Flash memory. As mentioned in datasheet it can transfer up to 1MB/s . For using this transfer speed can i use VCP (Virtual COM Port) driver or should i use D2XX driver ?
7. Trophy points. 1,288. Location. Chandigarh, India. Activity points. 1,756. i am designing a laser receiver for detecting a rotating laser ( less than 1us pulse at 600meter), now am using reverse biased photo diodes as it gives highest speed due to low capacitance, but.
Oct 8, 2009 · my project is design of high speed flash adc ..as a starting i am using tiq cmparator n doing the simulation in microwind,i have a few questions... 1. suggestions on some other simulator. 2.urgent ..what is the value of threshold voltage of pmos i.e. i m keeping the nmos width constant and varying the pmos width to get various switchings but at times the calculation of pmos width is coming ...
