Hello,
Could you please advise how to drive the DRV8711 STEP pin?
The DRV8711 is for steppers. Its input is STEP/DIR type.
The MSP432 is required to give positive pulses of specified number, at a specified period.
A sample code slvc575a.zip (for MSP430G2553) seemed a fully or partially CPU operation.
(software timer was found in [utiility.c Ln391])
for (i = 0; i < 1000; i++) { __delay_cycles(1000); }
Please tell me if you have an idea or a sample code which saves MSP432E401Y CPU load.
My idea would be, a combination of PWM and GPTM. PWM to repeat STEP pulses and GPTM to count the number of the pulses.
A solution of low CPU load would be highly appreciated.
