Hello,
are components for MCP47X6 DAC's family, and
MCP44XX,45XX,46XX digipot family planned?
That would be great. i am planning a project
with these components.
thank you

Hi Dirk,
I've just created a MCP47x6 component for you as it was very quick to do. This should now be available via a full database update.
I'll have a look at the digi pot components too and see how easy these will be to add.

Hi Dirk,
I've created two components to drive these today. I'll get them pushed to the v8 update system tomorrow for you.

Hi Dirk,
Sorry I was off work in the end on Friday, the new components are available now via the update system. Just change "Files in use" to "Full database" on the update window.

Benji, can you please create a DAC component for the MCP4921?
Thanks

Hi Rod,
can you please create a DAC component for the MCP4921?
Yes this is now done and included via the update system. Let us know how you get on.

Hi Benj, I updated the system but couldnt find the component mcp4921 available to use. I uploaded a picture of the screen.
Thanks

Hi Rod,
I've added a new component so you will need to do a full database update and then replace the MCP49x2 component on your panel with the new MCP49x1 component.

Hello,
When i go to help the "Check for updates" is grayed out.
You need to be inside a project for the check for updates to be available, either open an existing project or start a new one.

Hello Abhi!
Easier than you think. Start up SPI and check datasheet. You have to send only two bytes. First byte upper bits is command bits, the others are the data for the DAC.
UInt variable (base)
BYTE variable (data_h)
BYTE variable (data_l)
UInt variable (data)
Code: Select all
base=0b0011000000000000 //upper four bits are the config bits: Write to DAC_A, Unbuffered, 1x gain, output is ON
data=297 //anything from 0 to 4095
base=base OR data //merge "base" and "data" variables
Now, "base" variable contains the config and the data. Split it into two bytes.
Code: Select all
data_h=(base AND 0xFF00)>>8 //data_h contains the upper byte of merged data
data_l=base AND 0xFF //data_l contains the lower byte of merged data
Send the two bytes:
SPI:
CS -> low
send data_h
send data_l
CS -> high
End.

Hello! Bachman
good morning
Kindly excuse for the delayed reply, very difficult to find good time weekdays.
Yes, you made it sound very very easy, reading the datasheet is indeed very important but with examples as you mentioned "Piece of Cake"
Thank you again for this explanation, cheers.
Abhi

I've got only Flovcode v6. If it's ok, I'll share a working example.

Hi
In Flowcode v8 onwards there are many MCP DACs including the MCP4921 component under Outputs. Very handy to have.

Hello! Bachman and Chipfryer27
good evening
The explanation you gave in your previous post is indeed very helpful to understand how it works, and as mentioned by Chipfryer27 the component is read available in the FC8 and yes it is very easy to use, actually i made a mistake in one of the settings in the properties window about Prescale, while testing i found the correct setting and the component worked as expected.
Once again many many thanks to both of you for your answer/explanation.
