Hi John Could you please tell me what version FC you used for the test program files you had in the link you provided? Before i open files (I am on FC V4.5), i like to know what version they are, as i noticed sometime ago i tried to open a FC V3 file with FC4 and it got a little tense with that :D T...

Hi John

Thanx for the link and info! I intend to use the modules without the EB block, just as well
i saw the section about crosswiring the signals

Hi All,

Is there any working example FC V4 pic files for the EB063 wireless module, or anyone that has done
a working FC file for this module?

I would like to see actually how things are managed in the code using this module.

Thanx

Mark

Thanx Martin! I did bit of looking up in the datasheet and BoostC manual and yes i think you are correct. I think there are a few methods one can achieve this taking a closer look now at the question..... Does FC4 have any macros etc to do table read/writes? you need these commands to access and con...

Hi Martin Thanx for the link, interesting problem...but not what i am after. That link was about writing/reading from the main program running in the chip. My question was how to setup a compiler directive or whatever in the program code such that at program time(Hex file into chip), the data block ...

Hi All, I am looking at using a 18F25K22 for a project, where i need to setup a block of reference data in a section of the program flash memory. This data is not to be written to flash on every power up, but is put there at program time (when the chip is programmed). How do i setup this array in th...

Hi Ben

thanx for the feedback. All working as planned now...good idea about the sleep mode!
Forgot about that trick

Thanx

Hi Ben etc.... Working on a small project using the 12F629 in low power application and have few questions, project requires input/int and 0.5s pulse output....running on 3.2V battery. 1. What is considered the best low power mode? I am currently 32khz @ 3.2V. Datasheet sez at 2V (close to 3.2V) usi...

Hi Martin Thanx for all your input etc. You are correct in all you said about this bitbang method (tmr0) for pwm.....and you are correct that using a chip with pwm is much better. I did not have the 12F chip you recommended at the time, but i did dig out a spare 16F818 that has ADC/ PWM etc. using t...

Hi Martin, Thanx for reply. Your chart is pretty neat, but i figured a method that must allow the duty cycle to adjust without crashing...if one reads the ADC value it must be scaled to a range that such that the interrupt routine can finish looping before the next tmr0 interrupt. But there are stil...

Hi Ben Thanx for getting back, i have attached a simple form of the FC file that illustrates my exercise. Looking on the scope at the output pin, as i adjust the pot (1K centre tap to ADC input, ends to 5V / GND), i see the period shifting all over the place. I see at certain point of rotation range...

Hi Guys Been trying to pwm a dc brushed motor using a 12F675, pwm freq to be in khz range. Processor is running internal osc = 4mhz. Read pot on ADC to adjust pwm duty cycle. Since 12F675 has no pwm module i opted for using tmr0 as freq generator....but i have tried all sorts of interrupt algorithms...

Thanx Sean

Will take a look at that and fix it. Thanx again for your help!

Hi Sean

Ok great! Thanx very much. Any ideas about the LCD problem as mentioned
previously?
And also the question about trying V4 with V3 already installed?

Thanx

Mark

Hi Got a 16F886 running a 20x4 char display with ADC port 11 and 13. Currently running Flowcode V3.4.7.48 Issue is that in this version the LCD works fine, no problem. However when i try to use ADC port13 i get compile error. Does not get so far as to even generate any code. All other ADC assigned p...

Hi Ben/Steve

Been using V3 (full version - single user) for sometime now and
want to goto V4.2

Question: Is there a discount offered for existing V3 users
and how does one go about getting the discount? I have scoured
the MM website but it only offers V4 at the full price....

Regards

Mark

Thanx Ben Yes, did look at the header file before and as you say its not very well documented. But i will try to extract the info i need for the functions. So, according to your statement about the round to zero function I assume I am correct that if my var is always positive (always round down), th...

Hi I have followed the example on using floating point maths with V3 and with a bit of fiddling on my own got my program to run ok. However I cannot seem to find any reference to the functions that describes the operation thereof, or a list of the functions available! I have looked at boostC manual ...
