Hello Andy, Now, the output comes on 7i78 daughter card via GPIO pin(disabled highest-num Stepgen) with the same period.Its fine with the period now . Thanks for all the much needed help. BRAdit From: andy pugh To: adit bhargava Cc:

Re: [Emc-users] Need to add a faster thread base-thread with 100 microseconds, Compilation changes required !!!

So the highest-numbered  5i25 pin is connected to 7i78 and not 7i76 on which I was earlier redirecting output.I may connect the CRO to 7i78 then. From: andy pugh To: adit bhargava Cc: Enhanced Machine Controller (EMC)

Does this mean that if I redirect the PWM output to 5i25 GPIO pin(after disabling the stepgen),the PWM signal will be forwarded to 7i76 also ? So, it means I don't need to change the connection of Oscilloscope which is connected to 7i76 right now ? Just redirect the PWM output to 5i25 GPIO pin

Hello Andy, For serial_port_N option, is it for 7i76 card?I remember you suggested me to just disable the Stepgen on 5i25 card which can be done using only num_stepgens parameter and then this pin can be used for software PWM rather than 7i76 . BRAdit Sent from Yahoo Mail on Android On

Hello Andy/Sebastian, My mentor dosen't want to make any change in hardware FPGA cards. He instead suggest to use Universal Pulse Generator UPG100 http://www.eurias.nl/pdf/UPG100.pdf However, he wants to control the UPG100 through software, rather than manually changing the T-On and T-Off

Re: [Emc-users] Need to add a faster thread base-thread with 100 microseconds, Compilation changes required !!!

I wrote an incomplete software driver for a Micro controller which may output PWM. Unless you are familiar with programming in C on micro controllers I guess Hosmot is the best solution, especially if you already have one of these cards. On Mon, 18 Apr 2016 19:48:41 +0100 andy pugh
