Flowcode 3.1 Bug Reports

Steve / Ben, First of all a big thanks for the 3.1 update and all the work you have put in. Bugs? are : 16F886 can be selected but configuration options cannot be selected, error report comes up. 16F88 (Xtal) does not allow modification of config options (such as lvp, code protect etc.) this may be ...

Steve,

Is this all sorted now? If so I may have a look at my implementation to see why it did not work for me.

Are the amendments all in v3.1?

Thanks

Thanks for that. Looks like the ICD2 will be dropping off my list then.

Steve, Your post seems to suggest that the ICD2 connector is not actually capable of working with an ICD2, since an ICD2 can reprogram and debug all via its connector? Assuming that I am wrong (I hope I am) then I intend to update my ICD1 for an ICD2 in what I anticipate will be part of the EPE/Micr...

Stephen, I would have thought that the problem will be generating the AC signals on the pins needed for a bare LCD without driver chip, let alone multiplexing those signals. I recall that there are some PICs with in-built AC drivers for just this sort of project. However, I suspect that you will hav...

Michael,

How much ram you can use of what there is depends upon the BoostC license you have. Check the dialog when you program the chip and I think somewhere it says what your allocation is.

Hope this helps,

Steve / Michael, I am away now until next week and will check when I return (if it is still relevant). According to the PPP dialog OSSCAL is read and rewritten during programming, as to the value I'm not sure.

Steve, The 12F629 programs fine. I checked this by reading the code back with PPP and by placing various signatures in the hex that could be verified. However... Flowcode consistently says the code cannot be verified and gives the impression that programming may have been unsuccesful. The usual "hel...

Steve,

This topic is not a mainstream one for me but if you can spoon feed me with an amended fcd file to use (or not as the case may be) I will try and program a 12f629 and let you know what happens.

Benj, Whilst the solution works, the problem is that with large programs variable space quickly gets used up with what are effectively constant values, but which need a convenient way of being updated locally at compile time but not after.

Tummers, Rather than overwite the fcd file you can define a new chip. I for example can use 16f876B.fcd by copying 16f876A.fcd with modifications and it appears as a new chip on the Flowcode menu. This may also have the advantage that any update will presumably not overwite chip names that are not s...

Steve, One item for the update list (and I suspect more useful) is to enable the 'calculation' box to be either expanded horizontally or to provide a slider to view all text.

Hi Steve, One consideration is the I2C bus speed. Historically with 400kHz or even 100kHz bus I2C software has plenty of time, however with the 1MHz devices (which will increasingly become the norm) then a 20MHz crystal giving a 20/4 instruction cycle time or even a 4MHz crystal giving a 4/4 = 1 us ...

Steve,

Thanks for that.

I agree that a change in the next release will be a good move. Not only is the benefit of having a 'delay' of 0 greater than having 65536 (when 65535 is available) but the novice may be mystified by the concept of rollover and 65536.

Delay component when variable used and variable value is 0

Hi, I seem to have found a problem when a Delay component is used and when the delay is a variable and the variable value is 0. The Delay either lasts too long or an enless loop is created (I'm not sure which). The quick fix is a check to make sure the variable is not zero, however, as the delay is ...
