I was looking at the data sheet and looking at some old arduino code. We really need to be able to write to the eeprom. I am going to have to be able to set the dac voltages to 0 on power up. Very picky laser diodes are going to be hanging of the back of these.

thanks

Hey, Thanks for doing this. These are great!

Chad
Keep'm coming!

QESMAR, Did you get your arm boards?

chad

Hi thanks for digging into this. I am going to be playing with pwm on the 446re chip. This is a big help.

Chad

Hi,

I did try this a long time ago. I recently took another look and couldn't get it to work. Might (probably) be my fault.
Could you take a look at this again when you have the time? A little flash byte read byte program would be really helpful.

Thanks!

Spoke too soon. It defaulted to the nucleo version. I deleted it and re-installed from the FC updater. When I go to select it I get this error.
I also tried to install the one that you posted and it gives me the same error..

Chad

Good to go now! thanks

chad

Cool, arm just got a little bit better.

BTW, I did an FC update and it broke the 446re target. I can't select it in the build options and it broke my program. When it updated it it said it was not genuine.
I haven't tried to drop in the file you sent yet.

My bad, Try uart 4 pa0,pa1.

thanks,
chad

Hi,

I ran into a problem the other day. I tried to assign uart 3 and it wouldn't compile. I think there might be something funky going on..

Thanks,

chad

Hi Ben, that's awesome! I was hoping to use them all on the same i2c line so I didn't have to waste all of those pins and have multiple i2c bitbangs going. Just took a look at the component. Looks great. One suggestion if possible. on the 3d display It would be cool of the 0-4.1 could scale with the...

I'm still looking into this. There are definitely problems. There is a big matrix of works/ doesn't based on the variables set in the last post. It is also REALLY slow. I am thinking there is still something going on in the cal uart.. Still testing.. But I am really happy that we are getting closer....

I tried this again and it worked ok for me.. Nevermind..

Thanks

chad

HHm, ok I think i get what you are getting at. I will do some more experimentation.

thanks,

chad

It would be nice if 2 instances could run simultaneously on a machine. I frequently build test programs to get a handle on a component. For instance a display. Once I get the display set correct, orientation, pins, baud, colors etc.. I then want to transfer that to a working program. I don't know an...

Hey, while you are at it I am going to be using the mcp4728...Actually I am going to be using 4 of them.

thanks,
chad

Initial quick test results: So we are getting much closer. I able to receive some dmx data, A first!! Thank you! There are some complicated oddities around 'data channels', 'start channel' , 'usestart', 'getdatachan', 'recievedatachan' and number of dmx channels coming in. But, there is dmx coming d...

Ok guys, I will give it a good try this weekend..

thank you

chad

That would be great!!!

Chad

Hardware I2c would be really great!

Thanks

chad

So it has been 92 days and the component is still broken.

Not what I would consider stellar customer service.

chad

What stm board do you have?

chad

Second conformation. it seems to be fixed for me too.

Chad

Spent a couple of hours trying this again this weekend. Still doesn't work for me.

Chad

Sure!

The first is the ide and the second is cube mx. It allows you to set the config registers then send it to the ide.
