Two i2c clik doesn't work together

[luquas]

I'm using Necto 2.0, but in the previous version I was already having this problem. I was using clicker rtc 10 and TempHum 8, when I use one of the two, the code only works normally, but when I initialize both and try to use either only one works or the code freezes.

Hi,

Can you please attach your project here ?

Hi, how did you connect the 2 boards? Do you use the same I2C-port for both or do you use two diffrent ports for the two boards?

gerhard

[luquas]

Good Morning,
I use the same i2c, I'm using the PIC18F47K42.

[sgssn]

Hi
have you tried to put the specific functions of both Click boards into your task instead of init? Perhaps it is necessary to init the I2C-port every time ne for both of your click-boards.

Gerhard

[luquas]

I did that, the code crashes, executing only once each click and crashes in one of i2c's readtudo functions.

[luquas]

If I initialize rtc10 first and then tempHum8 the code runs once each click and crashes, if I initialize tempHum8 first and then rtc10 the code no longer crashes normally runs rtc10 and misread tempHum.

Hello luquas,

just my two cents.
The PIC can run on 3.3V and 5V, however, the Temp&Hum8 is a 3.3V only click. So, is your system running completely on 3.3V ?
What board with the PIC are you using?
The I²C frequency should be maximum 400kHz ( fast mode ).
Fortunately the I²C address is completely different of the devices, this shouldn't cause a problem.

kind regards
Frank

I did the test with stm32, if you use click temphum8 and rtc10 together or only one or none works.
using each one individually works normally but the two together don't. I haven't tested it with other i2c clicks.
Is there any way you can try to run temphum8 and rtc10 to confirm if there is an error?

Hi,

I have tested it and it worked for me, I was using Fusion for ARM v8 and STM32F407ZG.

I have attached my project below:

Regadrs,

[luquas]

Thanks IvanJeremic, I noticed that you used different i2c ports, when I use the same i2c ports it doesn't work.
I used different i2c ports one for temp and one for rtc and it worked too.

[IvanJeremic]

Hi,

MikroBUS1 and MikroBUS2 share I2C lines so i was using the same lines for this project.

Below i have attached another example, it is the same one except this time i used a shuttle click so i could connect both RTC10 and TempHum8 clicks to MikroBUS 1.

Regards,

Ivan.

[luquas]

thanks for your attention, that way it worked.
