Hi all ,
I am using a trial version of Flowcode 6 , and I have problem with the sensor board EB090
I can not read humidity or temperature value on the LCD display
With the EBM 004 ( Temperature sensor ) the Lcd display is blocked after the initialise instruction : DigitalTemp_LM75B1: initialise()
and with the EBM 016 : I have always the same value
I tried to put jumper in patch and default but always the same problem , there is no communication with the sensor board
You find attached the the 2 programs and some photo of the test .
Thank you .

Hi
It looks like you have the wrong pin properties set for SDA and SCL, they should be PORTC.4 and PORTC.5 with Default jumper settings.
I've attached a map of the EB090 pin connections

But the SDA and the SCL are in the pin RC3 and RC4 on PIC 16f877A !

True, for the hardware I2C.
But you can set the Flowcode component Channel to Software and change the port properties.
Or use the EB090 custom setting and wire jumpers.
Hope the map info helps.

ok , i'll try that , and I will post the result .
Thank you .

That was great , thank you !
It's running very well
