Hi Jonny, additionally I would say I preferred the way v5 components were modified, with a new window opening to configure external properties. Everything was clearly seen. Now all those properties are on the side property window together with position and other...and they don't stand out, now you h...

Thank you Benj!

Hi Benj,

How can I fix this in v5 myself?

Any chance to have some kind of option to use multidimensional LUT's in v6? As for now I am using supplementary code and C code blocks to reach values, and simulation does not work, just HW for debugging, which is not the fastest way. example of the LUT: #define N_TERM 12 #define M_TERM 13 #define C...

The same was in v5 and it's still not fixed, and now it's the same in v6, get a compilation error when you try to get a sqrt from floating point number:

Dont panic, the closed beta threads have been moved. As matrix are preparing for the open Beta, so starting with a clean forum

Hi Dazz,

Pheww I thought something happened to my account

What happened? I can't see all the topics. They are all gone!

Hi, One thing you should check is the pull-up resistors, that should be 47k as far as as I remember for communication speeds up to 400kHz. Otherwise system will not work. Edit: also sometimes if you are not using external interrupts, you need to do polling for reading the data. I'm also attaching un...

Hi Mathy,

I have already done this last year. Have a look at this post: http://www.matrixmultimedia.com/mmforum ... 48&t=11633

Hi,

here are some sample macros that I made and use very often:
Hope it helps.

Hi Benj,

Save your energy for v6 as v5 will soon be obsolete I am waiting for v6 and I am also hoping that I will be able to port my v5 projects to v6! Otherwise it will be "cry me a river..."

But as I can see from the C code it is for PIC mics. For ARMS and AVRS you would need to refer to datasheets for specific C commands. Why not just make a macro where you choose the settings like setings in the component windowby setting ones and zeroes?

Hi,

Would it be possible to make some additional macros to be able to change clock polarity and similar settings on the fly? Just in case you have multiple SPI devices with different settings.

Hi,

try changing it to:

Why do you have written the ASCII data to rom twice??? the first you begin at line 526 and end at 620, and then you do the same with defines starting at line 1443 and ending 1542. I think you should remove the first one, as I understand it is in the supplementary code. And the one with defines is in...

Try adding another #endif after the last #endif...

Mervin try writing and reading to one of the registers, like control register or some other static user register, to see if you get the same value back, which you wrote previously. If you get the same value back that means SPI is working correctly. Other only way to troubleshoot SPI communications i...

To be honest, it's one of the worst manuals that I have read. But from what I understood, I would suggest changing the sample bit settings to sample at the end of data output time. And also set the clock to Focs/64, to make sure the clock speed isn't too high for the chip. The clock polarity is not ...

Hello Mervin, You can always try it, I think there shouldn't be any problems to use it in reverse order Those NVM bits. If it fails, you can always use General I/O pins in FC by manually setting or clearing bits, to enable and disable the chip you are using. I attached a sample macro from my softwar...

Hello Mervinm, SPI_init initializes all SPI configuration settings for you SPI component, and setts the micro controller register for proper operation. It is not absolutely mandatory to use those DAC and NVM select pins, you can choose a port for them but leave them unconnected (I do this), and use ...

Hi,

or you can use http://www.ti.com/product/sn65hvd230 as a CAN signal driver.

Update: I changed the Data2Send array variable to Data2send non array type and it fixed the flip endings issue...I have no Idea why it is flipping, but now it is working like a charm, just the issue is that only one byte can be written...maybe MM will find a fix for this, but for me it is enough to ...

Updated RX and TX macros: But still some issues with the TX macro......should be 0b00000101 but sending 0b10100000...very strange

Hello everyone, So I was waiting and waiting, and decided to do it my self. I managed to write a code and macros for TWI (I2C) hardware. I attached the CAL file ARM_CAL_I2C.c and specific macros for I2C component, which you have to import, and also a modified defines function. The problem is very st...
