Hi Dario,

Thanks, it works fine. :)

Hi, I found some problem on the DemoBoard PWM. The calling function of the PWM \"EE_pwm_set_duty_f\" under flex_daughter_pwm.c\" calls the function via: EE_pwm_set_duty_f( pin-1 , *duty); so the chan = pin - 1, in which 0 = 1 in the DemoBoard PWM block under scicos. However, the chan is define as: #...

Dear Paolo, Thanks for the reply. the change in the first location oil file give new error: ***error message*** .\\libee.a(ee_thendin.o)(.text+0x16): In function `EE_thread_end_instance\': c:\\Evidence\\Evidence\\ee\\pkg\\kernel\\fp\\src\\ee_thendin.c:67: Link Error: Cannot ac cess symbol (_EE_sys_c...

Dear Paolo, Thanks for the reply. Please find the attached file for the zip file (which contain the map before and after the \"limit\"). The attached image is the memory map for the successful compilation (near to limit case, any extra block to the model will not compile), and seems like it just occ...

Hi again, I\'ve been testing the FLEX Full with DMB with the SCICOS generator, and when my constants, gains ... increase to a certain number I get the \"Could not allocate data memory\" error. From the error below, seems that the memory allocated is \"near\", anyway to reallocate the memory to \"far...

1. The current list of supported blocks is on the wiki! basically they are all the blocks which are under the FLEX and MCHP palettes... >> OK, I\'ve overlook simone\'s post saying the PID might be a bugs. 2. When we made the blocks for the demo board we tried as much as possible to cover almost all ...

Hi, Finally I am able to make simple DC servo position control works. A few more questions: 1. As there are some blocks under SCICOS Pack Blocks (such as PID or Intergrator), do you have a list of the supported blocks? 2. As for the PWM, with just 2 channels, only 1 motor could be driven, do you hav...

Hi, I tried using the PWM_DMB channel 1-4, with value 0-1 and probe the PWM 1L - Gnd,PWM 1 H- Gnd ...PWM 4 H- Gnd and there are no signals detected. I took a look into the source: flex_dmb_pwm.c, and there are lines : ************** if ((pin 2)) return; //** refuse not supported PWM EE_pwm_set_duty(...

Great,
Thanks. trying now.

Hi, Thanks again. 1. OK, will check it out. 2. I am looking into the usage of PWM block. Fromt he forum, I undertand that the PWM is fixed at 1ms. So what should I input to the scicos block in order to get 25%,50%, 75% Duty Cycle? (sorry i might have miss out some documentation but seems like I can\...

Hi Simone,

Thanks for your prompt reply.

1. I was using the PID block under MCHP16-linear. Does it means this one is not supported yet? If so, is there any workaround?

2. Ok, then I shall use the pwm with the H bridge

Thanks

Hi, A few question on the SCICOS PACK: 1. I have no problem to implement the PD controller by simply using the gain and a gain + derivative block. However, when I tried using the PID (either the PID block or integrator block), i get following error. *********** obj/dspic_main.o(.text+0x700): In func...

Hi, just to reconfirm: - you already follow the steps from the link: http://www.evidence.eu.com/component/option,com_mambowiki/Itemid,366/ including installing the USB driver at VID = 0x04d8 and PID = 0x0033 - then you still received the same problem. - what is the output of when you type \'findmsvc...

Hi,

I faced the same error but it gone after I installed the Visual Studio 2008 express. (previously i was using 2005)

Hope this helps.
