Dear Ben and Team, Its not often that you would receive positive feedback...however i had such a great experience this evening, i could not let the moment pass. I have been playing around with macros this evening, particularly the parameters and local variables feature. I was able to create some qui...

Re: gLCD printing number Problem

Hi Ben, Thanks for the update. Attached is the datasheet link for the display driver ssd1355 from Solomon Systech for those who may be interested. http://www.datasheetarchive.com/SSD1355*-datasheet.html. I did not post the file as it was approx 1.5mb .pdf. Also not sure of the copyright rules ( if a...

Re: Digital Compass

Hi John, Your compass looks great. it appears that we are playing with the same toys at the moment. I'm using the bigger brother version of the sensor, the tilt compensated CMPS09 as an angle sensor. A slight over kill, however i had it laying around from another project :D I attempted for quite som...

Re: I2C problem

Hi , try this example... its for a 16f877A, it should work on your chip, just change the target.. Note it has an LCD attached to read out the angle. BTW drop your pull up resisitors to 1.8k ( recommened by phillips) for 100khz... its possibly a contributor to your insatbility, depending on your rig ...

Re: USbee E Block

Chaps, I purchased one of these devices, it's very good, worth the money. I also purchased USB suite full version, direct from CWAV..It has all of the decoders etc... I have used it extensively on I2C both decode and bus simulation...Especially the packet display it's great for troubleshooting.. On ...

Re: MIAC Debugging

Aaaahhhhh....Thanks Martin...you triggered my memory....James has come from V3 to V5... Jumped over V4.. Now I seem to recall that the software driver disc supplied with early MIAC was ELSAM 2.3... The latest one is ELSAM 2.4, supplied with later versions of hardware V4 (etc)....maybe this is the di...

Re: graphic lcd

Hi, I agree with John, I went down the 4d route directly as I was too impatient to wait for the MM eblock..You can make it work, however it involves some additional effort.. If you do go down the 4d route make sure you get the cable with the display do you can play with it via the PC... They are awe...

Re: EEPROM Question

Hi George,

I seem to recall have an issue with location zero on the EEprom... try using another location..... location one or two for example

see how you go

Re: EEPROM Question

Hi,

I believe its a pic issue... Benj from MM put me onto it some time ago, and i did follow up on the Microchip website, which confirmed it.

It does not impact all PIC variants, just a few I believe...as a rule now I dont use location zero, just in case.

all the best

Re: PWM relay?

Hi, You can drive your 12 volt relay coil via a npn transistor wired in an open collector mode... You can use a bc337 transistor or similar with a 1k resistor in series between the pic output and the base of the transistor...the emitter of the transistor goes to ground, with the collector connected ...

Re: Flowcode for Beginners ?! any good ?

Hi, For what it's worth, I have been using flow code since 2010 with great success. It's fantastic for rapid prototyping... My background is assembler, COBOL, visual basic and some of the more obscure older languages....I my experience it's very fast to create concept projects thru to evolution of f...

Re: Flowcode for Beginners ?! any good ?

Hi Rob, glad to see that you are going to take the plunge. I agree with Enamul, the best option is to start with V5 what Flowcode version do I need ? TMP35 + pwm ? I2C temp sensor + PWM ? 1-wire Temp sensor + pwm ? IRD, Infrared ? as for the feature level, possibly you will require the pro version –...

Hi Rob, I am making the assumption from your posts that you are just starting out.. If my assumption is incorrect, please let me know. BTW.. I don't have any commercial association with MM, so your getting pure unbiased raw opinion Just a quick point on the cost...Depending on your employment situat...

Re: ECIO40 Driver

Hi there, The bad news is that across the board Vista is an absolute "bear" in the way it manages USB devices. I had a Vista OS on my rig for approx one year, in the early stages it was worse than painful with multiple devices as my toy shop expanded. The slightly good news is that you can...

Re: ECIO40 Driver

Hi rob, The drivers should be on a CD that was supplied with your hardware... It's directory on the CD is ELSAM2.4... All the drivers for every device are in this directory and sub directories..... I did not have to delete the drives... Go into the hardware device management and remove the MM USB de...

Hi fellow forum members, I have been playing with rate gyros for some time now and have been experiencing poor accuracy due to spurious readings from the rate gyro, potentially driven by vibration and other environmental considerations.

Re: MIAC Schematic

Hi Ben, The first thing to note is that to obtain either RS232 or I2C the CAN bus function is disabled. The CAN bus chip is driven by these pins in SPI mode. Look at page 11 on the data sheet. The MCP CAN chip was on a socket so I removed it and used a header to get to the pins for I2C...as I said e...

Re: Making a temperature probe

Hi Uli, A couple of points to keepin mind: What ever you use to waterproof should be kept thin as possible to allow heat transfer, Also the material you use should should have good heat transfer characteristics.. If it acts as an insulator then your temp readings will be inaccurate. Be careful with ...

Re: Making a temperature probe

Yes it was a large potting block of epoxy. the way we solved this was to place a thin layer of silicon grease around the component, then ap...
