The reason I use FreqMeasure and QuadEnc is because they use hardware ( but only on specific pins ) Takes all the fun out of setting up ISR's etc. The hardware does all the work and lets the rest of the code do its thing. but you make a valid...

This is my controller. I could have easily done a touch screen controller, but I like the tactile feel off buttons and knobs. I went 1000ppr because the stepper motor is closed loop with a 1000ppr encoder. It will be driving a 4mm leadscrew so...

if (FreqMeasure.available()) { Of course......I knew it would be simple Yes, I really am using a 1000ppr encoder and the 1ppr resolution for RPM. Now for the reason. If you use 1000ppr ( say you use 'A' or 'B' ) the individual pulses or not...

So I tried the serial output example and it worked fine, same hardware and connection /* FreqMeasure - Example with serial output * http://www.pjrc.com/teensy/td_libs_FreqMeasure.html * * This example code is in the public domain. */ #include...

Hi All I am trying to get an RPM tachometer working for my lathe using FreqMeasure.h the RPM range will be 1RPM-2000RPM The encoder is a generic Chinese ( OMRON style ) 1000ppr with A,B & Z. The Z outputs 1 pulse per Rev with 5v output The enc...

Problem solved. I used FreqMeasure on pin 22 and QuadEnc on pins 31 & 33 and just shared pin 22 and 31 from the Quad encoder. works flawless up to 2000rpm and now I get enc posn and RPM and as they use the hardware encoders it lets the program...

1000PPR and max RPM would be 2,000RPM at most Quad Enc 1000PPR was selected as it ties in with leadscrew closed- loop stepper encoder

I did find Quadencoder, but it was after I had the PCB made, so it is going to make it very hard to use. grrrr Direction is not a factor for the RPM, but essential for the leadscrew sync I am not using the SPI bus at this stage so I might be...

I am wanting to get an RPM value from a quadrature encoder that is used to control a stepper motor driving a lead screw on my lathe Full project https://github.com/MorryStu/Lathe-controller Unfortunately I am tight for spare pins on the...

Hi Mark Thank you for that. I do use indentation, but for some reason, when I pasted it it did its own thing. I added your changes to readButton() it it worked as intended, as you original thought. The switch,case,break etc was me just trying...

Well so far it is almost doing what I want. Currently it does not change mode when the respective button is pressed, just stays in "mm" mode and I am not sure why. The button light does display when the respective button is pressed, but no mode...
