Спасибо за ваши усилия по запуску счетчика частоты аппаратного модуля QDC. Я проверю код и объединю с главной веткой. Работает ли он так, как вы ожидали? т. е. диапазон частот и т. д. Оптоэлектронные преобразователи ограничат верхнюю частоту.

yes, I checked, it works as expected, the upper frequency depends on the parameter PRU_BASEFREQ 40000 // PRU Base thread ISR update frequency (hz)
at servo flow frequency of 40 kHz, frequency error from 1-500 = 0-5 Hz
 from 500-1000 = 0-25
 from 1000-2000 = ~50
 if you increase the servo flow frequency, the error will be less
after some time I could record a video with a demonstration and changing the frequency of the base thread

Thank you very much for your great work
 

Hello everyone!
I've been reading the forum for a while now!
I successfully installed rt1052.bin on ec300.
Linux is connected, Ethernet led lights up, connected.
But due to the MPG error I wanted to upload the new fixed bin. 3.1.3.
But I got these two errors.
Does anyone know the solution? Some have already run into this.


E Error during motherboard assembly: [session]
0000984 C No ACK received [__main__]

Whoops!
Ec300 Motherboard push button switch. Reset
Turn it off, press and hold the button, reset the switch when you turn it on.

It would be interesting to update the load modules, to put the QDC module in the servo thread. Given that the counting is done in hardware there is no need to update faster than the servo thread frequency. It might help with the frequency error as well.

Hello everyone I'm done trying to have my ec300 to work properly on mach 3 and I've already ordered a mesa card to get my mill running, anyway I really appreciate ll the work you be done on this project and would like to give a try at remora firmware, at least for learning purpose.
My board is a ec300 with the rt1052 chips on it, and I can't find the pin diagram for connecting the debug probe to flash it ?
I could only find the double stlink flashing method so far.

Thanks

Will this encoder code for A and index Z be added to an update in the future?
