Hi Team, I have tried to use the HP299 with a HP488 development board. i have tried using as per the data sheet. What settings should be used as comms speed. do you need to wire to port B RB6, RB7 and do they connect to the small D-type PCB socket header 6, 7 and GND. The data sheet is not much help...

Hi Team,

Is there a max string length that can be sent out of a RS232 port?

Hi Team,

Is there a problem with writing to Eprom on a 18F4520 i can read the data but when i write data then read what is there i always get 255.

Thanks

Hi Flowcode team,

Is there any thoughts of flowcode for 32 bit pic micros?
Is there any thoughts of doing flowcode to create windows aplication to use pic micros?
Keep up the great work the hardware and software.

Hi

I is because when you press the button 0 = 48 1 = 49 and so on so you need to take 48 from the result you get to get the number of the button you have pressed.

Hi Carlos,

Sorry did not understand how it was going to work. i have fixed it now i hope this is what you want.

Hi team,

Is there any example of how to measure a time between two rising edges on RB0 interrupt.
From 0 - 20ms with a accuracy of 1us or better. i can us flowcode 5 or Arm 4.

Thanks,
Wayne

Hi,

How do i post to V5 forum.

Thanks

Hi Flowcode team,

When will there be a free version of V5 so that you can try before you buy.
Keep up the good work.

Thanks
Wayne

How do i do a nop on arm.

Thanks

Hi Benj, Sorry for the confusion i wondered if there was a way to read in the interrupt a flag to see if the interrupt has finished. please see what i have tried to do too get a start pulse at the start of the interrupt and a stop pulse at the finish of the interrupt. i have tried do this using a fl...

Hi team,

Is there a flag that i can read in the interrupt to say that the interrupt has finished
to trigger an output.

Thanks,
Wayne

Hi Team,

i have a problem converting a float to int i have made a test file.
The problem is that it will not compile.

Thanks,
Wayne

Hi Team,

Sorry to be a pain in the neck.

Still cant get a programable 1uS timer grater than 2.7ms. need upto 30ms
i need to have two output's a start and a stop on different I/O pins.
The start would be generated on the interrupt and the Stop off some
flag??

Thanks,
Wayne

Hi Benj,

So i check the result flag and if = 1. do i set multiplier to 65535.
will this still give accurate times + - 1us of desired time.

Thanks

Hi Team,

I have just looked at the data sheet for the AT91SAM7S128 and the timers are 16bit so i guess that is the problem.
So there seems to be a way of connecting two timers together would that solve the problem.
and can you help with this if that will solve problem?

Thanks
Wayne

Hi Team,

Im just wondering if Sean has had a look to see what the problem with writing large numbers to the overflow register.

Thanks,
Wayne

Thanks i will wait for reply from Sean.
And thanks for all the help

Wayne

Hi Benj,

Can you see why i still have the problem that i cant get times grater than 2.7ms.

Thanks
Wayne

Hi Benj,

What have i done wrong i still have the same problem.

Thanks,
Wayne

Thanks Benj i will give it a go tonight.

Hi Benj

Sorry for the new topic.
Yes what you suggested works well but if i send a number grater than 64800 which gave me 2.7ms.
so fast.
This was what i was doing. if i wont a time of 30ms i do as then that is 30000 * 24 sent to the overflow register.

Thanks
Wayne

Hi Team, i need to generate times of upto 30ms with an accuracy of 1us. i can send timer1 overflow register decimal numbers the max i can send is 65535 because i think that the register is a 16bit so how can i use a 16bit which i think there is in the arm chip or is there another way or am i doing s...

Hi Team,

Can you supply the schematic to the EB61 board so i can see how it wired.
This is so i can wire a ECIO ARM on a piece of strip board.

Thanks
Wayne
