Thanos AMC1.6 USB 2DOF Motion Controller

[ne02005]

Hi Thanos, I`m back! again!!!!

Can You compile for me the latest firmware for a Atmega 1284PU both crystals? as you make a long time ago with old firmwares?
I`ll really appreciate it.

What makes the Arduino be slower than the AMC1.6 ?

[tronicgr]

They use different chip first of all. The crystal that is used on AMC1.6 is faster and allows 115kbps transfer speeds without losing packets at refresh rates of 1000 times per second. Arduino cannot refresh faster than 30 times per second without crashing (needs 33ms delay in transmission).

The reason is arduino uses generic libraries while the AMC1.6 was implemented in assembly for most of its time crucial code parts. That also means that is not easy to port it on different chip as well as the Atmega1280 for example as it has different core structure.

I had to build everything from scratch for the AMC1280USB controller including code and math section to make it as fast for controlling 6 motors in realtime response.

Thank you for explanation Thanos. I asked this because these days I met the LM4F120 LaunchPad Evaluation Board and seemed to me well promising because it manages to work with 80Mhz and is very inexpensive. You know this board? It would be a good option? Excuse by annoyance ...

Good night, Thanos.

have you thought about building a simulator as the brother of Sffair Bsmotion?

Your board AMC 1.6 serve to such a project?

Thanks in advance.

AMC 1.6 (esta substitui o Arduino UNO?)

Sim, qualquer uma serve. AMC é mais complicado porque terás que fazer ela. Arduino funciona bem e é mais pratico.

DSMhb1.2b (seria a ponte h que controla sentido e velocidade dos motores?)

Sim isso mesmo. Podes comprar uma ou fazer a DSMHB. Mesma coisa, comprar é mais prático porque não precisa fazer a placa.
Porém uso a DSMHB onde tenho a vantagem de poder substituir componentes defeituosos mas isso depende da sua experiência com eletrônica. Já apanhei muito dela.
Essa pode ser meio fraca (em amperes tens que confirmar com alguém aqui no fórum) mas é quase isso em termos de placa e preço pra dois motores:

Aqui outra:

Ou se eu usar Arduino Uno qual seria a melhor ponte h que controle a velocidade para os motores de limpador de para-brisa 12 40A.

A ponte-h boa pra Arduino é boa pra AMC.

Abraço!

Muito obrigado pelos esclarecimentos, mas vem mais uma dúvida a DSMhb1.2b ela suporta os motores de limpador de para brisa?
Pololu e a sabertooth também servem para motores de limpador?

Estou pensando em ariscar a montar o kit do Thanos AMC e a DSMHB, vou precisar de mais algum componente eletrônico (placas) além desses?

Qual torque que vocês acham ideal para o joyrider? tem alguma relação entre peso da pessoa e torque?

Me desculpe pelas perguntas detalhadas, querendo tudo mastigado, sei que tem várias coisas que já foram discutidas no forum, porém entram peças novas, dúvidas novas, problemas e acabamos repensando se aquela linha de projeto que vamos realizar será o melhor ou não.

Obrigado novamente.

Um abraço a todos.

Dsmhb é muito boa. É a que eu uso. As outras nunca usei mas o pessoal usa elas também.
Com a AMC e DSMHB na mão não precisa mais placas.
O simulador tem que estar sempre em equilíbrio para os motores fazerem o mínimo de força possível.
O torque do motor de para-brisa é bom desde que tu não aumente a alavanca. A original que vem com a máquina completa do para-brisa tem menos de 10cm eu acho.

Nessas lojas online tipo multcomercial e soldafria (brasileiras) deves achar tudo o que precisa pra montar essas placas.

Mãos a obra!

Hi Guy's,

Please write in english !! There is a sub forum for other languages !

This topic must stay in english ! Please

[sanmarcelllo]

I'm sorry , it was the excitement of building a simulator !

Follow my doubts

AMC 1.6 ( this replaces the Arduino UNO ? )


PostBy RafBR » Yes , any will do . AMC is more complicated because you must make it . Arduino works well and is more practical .

Sanmarcelllo DSMhb1.2b ( h would be the bridge that controls direction and speed of the motors ? )

PostBy RafBR " Yes that's right . You can buy one or make DSMHB . Same thing , buying is more practical because it does not need to make the plate .
But use the DSMHB where I have the advantage of being able to replace defective but it depends on your experience with electronics. Already got her a lot .

This can be rather weak ( in amperes have to confirm with someone here in the forum ) but is nearly so in terms of board and price for two engines :

Here another :
http://www.robocore.net/modules.php?nam ... prod = 295 & l

Sanmarcelllo Or if I use Arduino Uno which would be the best bridge h to control the speed of motors for windshield wiper 12 40A .


The h - bridge is good for Arduino good for AMC .

Hug !


Sanmarcelllo RafBR Thank you for the clarification , but has one more doubt DSMhb1.2b it supports engines cleaner windshield ?
Pololu sabertooth and also serve to cleaner engines ?

I'm thinking of risking assemble the kit and Thanos AMC DSMHB , I need some electronic component ( plates ) besides these ?

What do you think torque ideal for joyrider ? have some relationship between person's weight and torque ?

Sorry for the detailed questions , wanting all chewed up , I know there are several things that have been discussed in the forum , but entering new parts , new questions , problems and ended up rethinking that line project we will perform better or not .

Thank you again.

A hug to everyone .

RafBR Dsmhb is very good . It's what I use. The other never used but the staff uses them too.
With AMC and DSMHB in hand no longer need plates .
The simulator must always be in balance for the motors do the least possible force .
The torque motor windshield is good since you do not raise the lever . The original that comes with the complete machine windshield is less than 10cm I think.

These online stores and type multcomercial soldafria ( Brazilian ) you should find everything you need to assemble these boards .

Hands-on !

Thank you vicpopo
