I am at the start of a project and still need to design the hardware. The board I am working needs to read a wheatstone bridge and translate this to 0-10V and or 4-20mA output I need someone who can write a component macro for the DAC8760 and MAX11270. The DAC8760 will have priority Please feel free...

My name is Jeroen and am the owner of Holtha OFS. I use Flowcode V6 for basic products, but I now got a project in where I am looking for a programmer. This project involves the ECIO40P16 from Matrix, a DAC8760 and a MAX11270. Please contact me me through PM with your details and rates, and experien...

Thanks Benj. That did it. I use the ECIO40P for small projects I do. The test bench project I am working on at the moment is using the ECIO40P to control a SEW VFD Drive through CAN. If this will turn out to be a reliable success, i will use that for the smaller VFD projects I have and hopefully kee...

"Hello" I receive a String, which I use to calculate Degrees which I then send forward on RS232, but the result is always 0.00000 Degrees = stringtofloat$ (Pulses_String) * (360 / 7685) Degrees_Calculated = floattostring$ (Degrees) Pulses_String (String) Degrees (Float) Degrees_Calculated (String) D...

Thanks Medelec,

I noticed that my interrupt on Z_Wire caused the missing counts.
I stayed with the Int on A-Wire.

Thank you

Hi Martin, Thank you for your reply. I started from scratch again, and tried to keep it simple. I do not really need RPM, I need to measure the distance a chain has traveled that is connected to the motor. The motor runs between 15 and 3000 RPM. I tried to keep it simple by using A-Channel on INT0 a...

Hey Guys, I need to read an 256 step encoder. I've been reading the forum as I was having problems with steps missing on slow turns of the encoder. The forum said that the checkforchange should be checked more often. So I did, and now the opposite happens. It is missing steps on higher RPM's. The so...

This works great, thank you Benj.

Hi Guys, I want to capture 232 serial data, modify the data if needed and forward this to another serial port in the PIC. (USB Serial for now) But when i Recieve_String on RS232 and then USB_Send_String I am seeing weird things on PuTTy Serial Monitor I'm seeing double NMEA types but with different ...

Thanks Benj, that did it

I have tried to install the driver that I downloaded from matrix through windows device management and windows says that the HASH file is corrupt.
Anybody got another (older) driver for the ECIO's?

FYI I'm using Windows 8.1

Is this also true for the ECIO40P 18F4455?
Under 'Compiler Options' I cant make any changes to the settings as I have selected 'Default'

Hi guys, Just recieved 4 new ECIO40P's from farnell today. I have used ECIO40's before on other projects and had no problems with them. How ever, today I wanted to program the first ECIO40 that came out of the box and this showed up: Building CASM file Memory Usage Report =================== RAM ava...

Hi Guys,

The EB063 data sheet mentions that a voltage level shifter is used.
But the data sheet of the Alpha-TRX*** says the module can be used between 2-5 Volt.
Is the data sheet for the EB063 outdated or did I miss something in the Alpha-TRX datasheet?

Hi Guys,

I got the Professional Bundle of V6 PIC and DSPIC.
Where can I find the DSP Kalman Filter?
I can't see it under the DSP menu

Dutchie

I found info on the back of the switch about the excact frequency of the switch. 433.92Mhz

I changed the program a little.
I am now searching for signal strength on all bandwidth between 170 & 175 in Update_Center Frequency
But still nothing.

What am i doing wrong?

Dutchie

Here I am again. I am trying to figure out how to find a RSL 433Mhz Conrad Wall Switch with the EB063 E-Block. At home I am using 1 channel of this wall switch with a reciever that got supplied with it. http://www.conrad-electronic.co.uk/ce/en/product/646655/Radio-2-channel-wall-transmitter-RSL-No-o...

Hi guys, I want to write the time from GPS to the EB076 Display. I can print number Hour_Byte then print ":" and Print Number Minutes_Byte and Print "." and then Seconds_Byte But then I have to calculate the X and Y position for every print command. Is there a simpeler way? Something like this? Disp...

Thanks Benj,

I changed the GPS true USB to a higher baud rate but forgot to set the proper baud rate on the board

Dutchie

Good Morning guys, Yesterday I wiped the dust of my winter hobby. Not that i think that summer is finished, but I felt like playing with it. I am getting stuck with I think getting data from the serial connection from the GPS. The program does not go passed the first loop. The state of GPS_Data_Vali...

Thank you Benj.

It would be great if you guys can, it looks like a great little board to play with and make something practical with it.

Thank you so far

Hi Benj,

That is the display it comes with, only the manual says the display comes with the HX8347D controller.

Happy New Year to you all, For the last couple of days I've been surfing the net for an all in development board that is after playing with it, actually useable. I've come across the MikroMedia for PIC24EP and it seems to have everything you may need, touch Screen, measure G-Forces, SPI, I2C, etc ec...

Hi Medelec35,

Thanks for the tip, very useful.

Dutchie

And while I do 1 more check on the calculation, I found the problem.

I by accident typed a (Space) in the Pi number.
Float = fmul(Float, 3. 1415926)

Problem solved.
