Hi
a quick update on the above. I have wound back the component label fcpx file for the combo board from V3 to V2 and it seems to have resolved the problem.

But if someone could take a look at it please

Hi I have just updated all the components in V8 and when I try to use the BL0114 combo board the display is corrupted with large squares saying "component label". where the LED and switches usually are. Is anyone else having this problem? (see attachment) It is quite important as our stude...

Hi BenJ Thanks for this. if the BL0032 is the original EBlocks ultrasonic sensor then I have that one working OK. The grove ultrasonic sensor appears to just give random numbers if you try to measure in CM or inches if you set it to read in mm then it appears to measure in CM but not that accurately...

Hi BenJ
I have attached the program. But it is the one from the wiki with the display type changed. As I said this is set to read in mm but is more like CM

Hi I am trying to use your Grove Ultrasonic sensor. I have downloaded the example program from the wiki. It appears to work but the example program is set to read in mm and it is more like CM, although it is not very accurate. When I try to read distance in CM or inches then the readings just appear...

Thanks Ben Ii appears for some reason that either the code or the servos don't like being set above 250, if set at a max of 250 then they stay enabled. Regards Gary Edit Further to the above, I have changed the program slightly and added a few commands to move some more servos. I have found that if ...

Hi Ben Thanks for the quick reply. regarding the initial position I have been placing it as close to where it starts as I can, I was just hoping there was a way to slow down the first movement. Regards the servos not locking, this is still happening. Can you please check the attached program and exp...

Hi All I would appreciate it if someone could help me with a little information on using servos with flowcode 8. I have a small robot which uses 6 servos and have a few questions. 1. As soon as I enable the servos they shoot off at max speed to position 128. I can change this position by using set p...

I have had this updated and my original program now appears to work OK, Please accept my apologies for wasting your time. Just for your information the program you sent still gives a reading of -226.45 Sorry ...

Thank You will update and try again

Hi Ben The number appears instantly and if you press reset the number still appears. I have got rid of the problem by putting a 10ms delay in the loop. The modified program you sent 1. It says this program was built using a newer version of flowcode and may not run correctly, although I believe my v...

Hi Benj Thanks for the quick reply Unfortunately this is with V8.1 and all latest updates. The problem I have is that we are a college and the students are learning to program and little issues like this are difficult for them to understand. Not only that, I have concerns as to how the examiner will...

Hi I have a very simple program to read the temperature using a grove temperature sensor. The program displays a message "Temperature is now" on the 1st line and then displays the actual temperature on the 3rd line. The problem is that it also prints the digits after the decimal point on t...
