Progress of sorts, NI Visa works well with serial component in FC6, For slave function I've discovered Labview doesn't like your ECIO dll call library 'string' data type parameter for 'Data_In ' within the USB_Transfer sub VI , replace 'string' for say 'array' I32 and place an array indicator ...

Error is generalised to the function call, all parameter wires are connected incl error node, all wire are of compatible data types (no wire errors) even removed the subvi and wired the function call into the main VI without success so I guess I've come to the end of this particular road

I ...

Both 64 and 32 bit labview can be installed from the same licence and run side by side on the same machine so one problem solved, However in the USB transfer (Subvi) the call library Function for ECIO_api.dll, has an error. Open and Close Calls are OK just transmit has the problem

The error ...

Hi Benj
After a little digging turns out Labview 64bit is has been around since 2009 but it looks like the 32bit dll can't be persuaded to join the party. Labview installed a 64 bit version by default on my machine (not paying attention). Good news is you can install both 64 bit and 32bit from the ...

Hi Labview 15 is calling out an error in the flowcode sample programs for PC USB communication, Labviews debug suggest the ECIO api.dll version may not be 64 bit compatible. Is there a compatible version available and can you point the way? Thanks Gary

Hi also experiencing I2C issue since the last V6 upgrade using a PIC with the sht21 humidity sensor
Previous version worked well but following the latest upgrade to 6.1.0.0 ;
* wouldn't compile until I replaced PIC CAL file (from forum)
*With channel set to software PicoScope can't decode though I ...

Flowcode v5.5 Pro

Programming skill in 'C' are non existent (that why I use Flowcode, great product ) looking for any tips,tricks for this problem

Hi

Anybody tried a log analogue input to linear digital? with Flowcode and PIC
thought I might try pre-loading an EEPROM with a anti-log table or a possibly a (twin table) LUT If anybody's done this before would be nice to hear from you

Hi

Is there any way of driving the E006 ICD function at a lower than the 5v supply voltage, I'm trying to debug an SPI comm to a functional chip with a voltage limit of 3.3v on the SPI pins, the MCU i'm using is a PIC18LF2550 which will operate at 3.3v and I'm pretty sure it's possible with the ...

HI
Can the SPI legacy component in Flowcode be configured in slave mode for PIC16fxxx with built in SSP module?
Gary

Benj

Thanks for the quick response, the hardware is destined to fit in a 'memory stick' size footprint so I'd rulled out SD and micro SD's but I accept your tip on SPI and flash with thanks

Hi

I have a data aquisition project and need to store 99 sets of data around 200bytes/set aquired by PIC18F4550 from a sensor with SPI comm, as the data needs to be secure I'm loading each data set to the internal EEPROM. I am considering an additional 32kb EEPROM using the PICs to buffer the data ...
