Help with PWM on LPC2468
Locked
|
Hi,
I am trying to use the PWM0[1] and PWM0[2] on eLua Demo Board( LPC2468 ), but at the exit pin I only see a DC level. This is what I am doing: pwm.setclock( 0, 12000000 ) pwm.setup( 0, 5000, 90 ) pwm.start( 0 ) pwm.setup( 1, 5000, 30 ) pwm.start( 1 ) Am I missing something here? Thanks, Ives _______________________________________________ eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Hi,
Thanks for the report, I'll take a look at it.

Hi,
I just tried some more things with no good result, so I gonna report my tests for you know better what is happening. At first I tested this code on EKLM3S8962 and it worked. pwm.setclock( 0, 12000000 ) pwm.setup( 0, 5000, 90 ) pwm.start( 0 ) pwm.setup( 1, 5000, 10 ) pwm.start( 1 ) so I tried it on eLua Demo Board and again my exit signal was a 2.8V DC. I turned on all PWM on Demo board, and saw all the pins that have PWM function, and again the exit was a 2.8V DC. Then I tryed to use I/O function on some of this pins to see if there were any connection problem, and all the pins worked properly. I have a deadline of a week, is possible to solve this til then? Could someone else test this function on LPC? Thanks again Ives

One thing that may or may not have been brought up yet is that this
platform requires pins to be configured for certain outputs to work. I'm not sure what the defaults are on this board, but you may need to set the contents of some PINSEL registers. pwmled.lua does this: elseif pd.board() == 'ELUA-PUC' then pwmid, tmrid = 7, 0 local psel = cpu.r32( cpu.IO_PINSEL3 ) psel = bit.bor( bit.band( psel, 0xFFFFFCFF ), 0x00000200 ) cpu.w32( cpu.IO_PINSEL3, psel ) It likely wouldn't be too hard to have a wrapper function that does this, similar to the mbed one, since the configuration models are almost the same for these platforms. The PINSEL register descriptions should be in the LPC2468 manual.

Thanks James, that's probably the problem. I'll try to fix it in SVN tonight, although your solution provides a nice workaround directly in eLua.

Actually, I'll probably not try to fix it directly in SVN, since the I/O configuration of the LPC2468 allows multiple pins as outputs for the same PWM channel. As I don't know what pins Ives is trying to use, probably the best method for him is to use the method above, tailored to his specific needs. Datasheet to the rescue! :) Best, Bogdan >> >> On Tue, Aug 3, 2010 at 3:44 PM, Ives Cunha <[hidden email]> wrote: >>> Hi, >>> I just tried some more things with no good result, so I gonna report my >>> tests for you know better what is happening. >>> At first I tested this code on EKLM3S8962 and it worked. >>> >>> pwm.setclock( 0, 12000000 ) >>> pwm.setup( 0, 5000, 90 ) >>> pwm.start( 0 ) >>> pwm.setup( 1, 5000, 10 ) >>> pwm.start( 1 ) >>> >>> so I tried it on eLua Demo Board and again my exit signal was a 2.8V DC. >>> I turned on all PWM on Demo board, and saw all the pins that have PWM >>> function, and again the exit was a 2.8V DC. >>> Then I tryed to use I/O function on some of this pins to see if there were >>> any connection problem, and all the pins worked properly. >>> I have a deadline of a week, is possible to solve this til then? >>> Could someone else test this function on LPC? >>> >>> Thanks again >>> Ives >>> >>> 2010/7/27 Bogdan Marinescu <[hidden email]> >>>> >>>> Hi, >>>> >>>> Thanks for the report, I'll take a look at it. >>>> >>>> Best, >>>> Bogdan >>>> >>>> On Tue, Jul 27, 2010 at 3:20 AM, Ives Cunha <[hidden email]> wrote: >>>> > Hi, >>>> > I am trying to use the PWM0[1] and PWM0[2] on eLua Demo Board( LPC2468 >>>> > ), >>>> > but at the exit pin I only see a DC level. >>>> > This is what I am doing: >>>> > >>>> > pwm.setclock( 0, 12000000 ) >>>> > pwm.setup( 0, 5000, 90 ) >>>> > pwm.start( 0 ) >>>> > >>>> > pwm.setup( 1, 5000, 30 ) >>>> > pwm.start( 1 ) >>>> > >>>> > Am I missing something here? >>>> > >>>> > Thanks, >>>> > Ives >>>> > _______________________________________________ >>>> > eLua-dev mailing list >>>> > [hidden email] >>>> > https://lists.berlios.de/mailman/listinfo/elua-dev >>>> > >>>> > >>>> _______________________________________________ >>>> eLua-dev mailing list >>>> [hidden email] >>>> https://lists.berlios.de/mailman/listinfo/elua-dev >>> >>> >>> _______________________________________________ >>> eLua-dev mailing list >>> [hidden email] >>> https://lists.berlios.de/mailman/listinfo/elua-dev >>> >>> >> >> >> >> -- >> James Snyder >> Biomedical Engineering >> Northwestern University >> [hidden email] >> PGP: http://fanplastic.org/key.txt >> Phone: (847) 448-0386 >> _______________________________________________ >> eLua-dev mailing list >> [hidden email] >> https://lists.berlios.de/mailman/listinfo/elua-dev >> > eLua-dev mailing list [hidden email] https://lists.berlios.de/mailman/listinfo/elua-dev |

Yep. I'm currently following a policy of configuring these sorts of
things automatically if there's only one pin that can be used for a configuration. I think what would be nice is for platform.c to have data on usable pin mappings for various peripherals that are supported, and if the user asks to set up the peripheral by referring to a pin rather than the device id, it will attempt to set up the pin for that use. Admittedly there may currently be some scenarios where if something like CAN is set up on STM32 there may not be a way to revert the pin to default behavior without a reset (though I would have to check).

Hi.
Thank to you I could fiinally make it work, but the function cpu.w32 only worked when I used hexadecimal address. Is something wrong with platform_conf?

The output is -536690660, which is the same as E002C01C, but when I use cpu.IO_PINSEL7 on function cpu.w32, the program freezes.
If I use 0xE002C01C it works. 2010/8/4 Bogdan Marinescu <[hidden email]>
