PSoC™ 4 Forum Discussions

good morning evry one

Am working on a project with psoc 4, i want to pilot a motor brushless with a drive carte "BLHD30K", and i want to calculat the speed motor!!

this drive carte give a Pulse signals (pulse width: 0.3 ms) of 30 pulses per revolution of the motor output shaft are output in synchronism with the motor drive.
Motor speed can be calculated by measuring the SPEED output frequency.

Motor speed [tr/min] =(SPEED output frequency (hz)*60)/30

SPEED output frequency =1/T
 

like that i can also calculat the position of the motor by using an interruption every 30pulse -----> one revolution (tour),

but i dont khnow how to calculat that? any idea !!

thank you

I've iterated several hardware designs but everything I try leads to a code 43 error. I'm using osh park to manufacture the boards. Using Saturn PCB design I've calculated the impedance width of 45 mil. I've included my design files. What do I need to change to get it to work appropriately? 

The only time I've had any success is when I do not copper fill the entire board and route the traces without any tvs, resistors, or capactors attached. Yet without the tvs, its functionality lasted only a couple of hours before it was no longer functional. Thanks for the help.

Hello,

When I try to compile the code including the function of CapSense_GetSensorCp() in the project with Capsense block,the system always fail with "Build error: undefined reference to `CapSense_GetSensorCp'",anybody know it?

Using the PSoC4 Pioneer Kit and a 500 PPR encoder I am trying to get it to count up when I turn the encoder in one direction then count down hen turned it the other direction; but it is not working correctly.

When I turn the encoder in what I believe to be the count-up direction (A leads B) it does count up.

When I turn the encoder in the count-down direction (B leads A) it does NOT count down.

It just toggle back-and-forth between two values.

I capture the counts through Hyper Terminal and log them to a .txt file.

My project and the text file are attached.

I manually edited the .txt file to give indicators when I changed encoder direction.

Thank you,

Doug

I want to use thermistor component in my design. Default values is max 50 degrees but I need 100.

What resistance parameters I need enter to configuration ?
