Re: Pic32mz DMX SLAVE BROKEN
hi chad I was trying to get the dmx recive working on an Arduino uno back in 2017 all sorts of strange things ie would recive channels sometime but it depended on the value of the channel before it , ie could recice 0,50,30,40 but not 255,255,255,255 , being an Arduino there was other code on the ne...

Re: no me funciona el DMX esclavo
i had a simular problem using avr chips in the end i gave up , i dont think it is corectly detecting the start of the dmx transmition . i could get it to work only for some dmx values , moveing the sliders on the lighting desk would make it totaly fail with some values , from memory i think 255 was ...

Re: 16Mhz on atmegs238p
thank you for putting me on the right track maybe flowcode can look at fixing this bug as it makes the dmxslave unuseable with the atmega328 and probably other simular chips , below are my findings i changed the crystal to 20 mhz on an uno as the chip should be able to work at that and it is a supor...

Re: 16Mhz on atmegs238p
thank you that is very interesting as the i2c gave me major problems untill i set it to 100k , there was then the anoying problem of the changed not being saved so i had to do the same change of i2c speed every time i loaded the program . this has now been fixed so it saves the changes i have now co...

Re: 16Mhz on atmegs238p
this may be part of the problem it appears the recive requires one start bit , 8 data bits and 2 stop bits but your uart component does not appear to support that format ? when i have looked at doing the recive the hard way

Re: 16Mhz on atmegs238p
thank you , i am working through the dmx slave again double checking things again ie clock speed. the reason i wanted to use the atmegs328 chip at 16mhz it get rid of the arduno boot loader as suspected that may be messing up the dmx slave , using hardware as recomended here but still the same probl...

Re: 16Mhz on atmegs238p
thank you that worked for the atmegs328 chip but strangly does not for the arduino boards that use the chip , not a problem for me at the moment but will be for anyone trying to use the 3.3v version of a nano that runs at 8 mhz i think it is a little bit confusing as you have a downward arrow and ca...

16Mhz on atmegs238p
i think i have found the problem with the DMX recive ( slave)i asume it needs the controler to run at the correct speed , i have writed a simple program to flash a led and it goes at twice the speed it should then i noticed you dont support the 16mhz controlers used in the nano and uno , only the 3v...

Re: Component Required
you will be better looking at the higer swicth value first and use the > rather than = to allow for tolerences in the components ,, is if the vales shoud be 128 then 100 use > 114 as it is in between the 2 values , dont forget the board is probably built using 5% resistors giveing a max error of 10%...

Re: Component Required
this may help you it is only an idea at the moment as there are some serious issues with the dmx recive , it uses an uno and lcd sheild the buttons alow you to set the dmx address and save it , it should work as it is if you want to play with something

Re: Component Required
i have used the lcd sheild just reading a single analogue value and then lots of decisions but i agree a component would be good as you can get nice keyboards that only use a single pin of you microcontroller and have up to 16 buttons

what i am trying to do is read the dip swicthes and then do something with the 9 bit dmx address (512) one problem is i can set the DMX slave to recive 512 channels it says the max is 512 but when i enter that is changes it to 256 it would be a lot better if i was able to change the dmx start addres...

i am not sure if i understand how the dmxslave should work . i am asuming it should wait and time out without a dmx signel if so it does not it just hanges there choice what times i set for the time out second issue i am asuming a need to set the datachannes to 512 to recice all 512 channeles . when...

i am trying to get the dmx to work using an attiny 84 ,,, there only appears to be the software option wicth is in itself not a problem but it default to ports not on the chip i am trying to use and they are greyed out so i am unable to use pins that are actuly on my chip
