The stepping motor example does not work. #262

Closed ar055 closed 4 years ago

ar055 commented 5 years ago

Timer_group: timer_init(214): HW TIMER divider outside of [2, 65536] range error. not work esp32 pico and esp32 generic dev board.

the0ne commented 5 years ago

@ar055 can you provide a sample lua script that triggers the error?

ar055 commented 5 years ago

put:

s1 = stepper.attach(pio.GPIO26, pio.GPIO14) get: E (234606) timer_group: timer_init(214): HW TIMER divider outside of [2, 65536] range error put: s1:move(10) stepper.start(s1) get: board freeze

@ar055 I can reproduce both, thanks! btw: the Lua-RTOS doesn't actually freeze - if you hit [Ctrl]+[D] you see the message "Lua RTOS-running-ESP32"

the0ne commented 5 years ago

@ar055 you may try using commit b0ac730 from #266 as this removes both issues @jolivepetrus please check #266 - additional changes might be required in case timing is changed by modifying the divider

@ar055, @the0ne,

Hi guys, I ask you some patient on this issue. I have to review some items, and adapt the internals using the Lua RTOS timer driver to ensure that the use of steppers haven't collisions with other Lua RTOS features that also use timers. In this review I will solve this issue. 2 or 3 days will be needed for that.

config.divider = 2; it works for mi! EN_PIN = pio.GPIO12 pio.pin.setdir(pio.OUTPUT, EN_PIN) -- ENABLE ON pio.pin.setlow(EN_PIN) s1 = stepper.attach(pio.GPIO27, pio.GPIO14, 48, 200, 680, 6) s1:move(100) stepper.start(s1) -- ENABLE OFF pio.pin.sethigh(EN_PIN)

@ar055 that's great to hear! Can you confirm that the amount of steps and the timing are correct?
