Re: gLCD Compatibility

Hi,

The 4d displays are available with or without the EBlock...

I protocol using an eblock the jump to the raw component for production

I have purchased 4d displays directly for the vendor via the web..


Hope that helps

Re: Problem with heaps & Stacks when compiling

Hi Martn,

You make some very good points.

When you get a moment, would it be possible to create one of your very informative tutorial posts on the topic?

A basic how to on watch dog implementation would be very helpful.

Hope it's not a too cheeky request :mrgreen:

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...

I was really quite straight forward... The only thing I didn't realize I had to do was to use a get data command after I had requested the HMS info..Once I did this it was up and running..

Hi John,

It's pretty late here now... I will check driver versions for you tomorrow.. I'm using FC V5.3 also.

Can't recall any set up issues... Think I used drivers from CD ELSAM 2.4

Hi Rob,

Your very welcome, and thank you for the feedback. At some point you may wish to consider windows 7... All of the flaky USB behavior will go away... In the mean time you can reasonably operate with this work around.

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: Variable Voltage Signal using PWM

Hi James, I have used this technique a few times to generate a variable voltage... The best way to provide control over the output voltage is to use an op amp. This way you can choose the rail voltage and by playing withe the gain of the amplifier you can manage the size of the output swing vs the i...

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: Reading Resistance....

Yes they are easily cascadable

On the microchip site there is an application note, which describes in detail how to address multiple devices...

I have not had any experience with AD ... Looked at them briefly, then chose microchip...I can recommend the MCP solution.
