Re: Compétences channel Z-Uno

Salut,

Je ne sais pas si j'ai une compétence, mais j'ai passé un peu (voire beaucoup) de temps sur le Z-Uno alors je peux peut-être t'aider!

Zwave range and power

Hi, I installed a zuno. It's 15 meters far from the controller (razberry). The communication didn't work, so I added an external antenna. Not better... After several tries, I found out that the communication works if the zuno is powered by the USB port. In my project, it's powered by an external AC-...

Re: float conversion

First, thanks to spend times on my problem, even if I found a different way to move forward. For the DS18B20 voltage, I did like the example and it works fine. My project isn't running all the day (yet), so I have no feedback for the moment. Peter, you have found the library I used. I can't used the...

DS18B20 in argument

Hi, I try to make a function with the class DS18B20 in argument: void lectureTemp(DS18B20Sensor * capteur, float* temp, int ligne) When I compile, I get this error: C:\Users\Jerome\AppData\Local\Temp\build8533003694867026979.tmp\_Test_ucxx.c:673: error 98: conflict with previous definition of 'lectu...

Re: float conversion

It works if I convert the float to a string and I print it. No Crash. So it's definitely a soft problem.

Re: float conversion

First, I took the Arduino LiquidCrystal_I2C library, and I made few changes to make it works with Z-Uno. It's small changes, and I don't remember all I did, but : - the array declaration with default values don't work: uint8_t row_offsets[4] = {0x00, 0x40, 0x14, 0x54); // default values are ignored ...

Re: float conversion

I want to output the string to a I2C LCD screen. The print method with float argument doesn't work: after few call, the screen starts to disp special symbols instead of float value. If I use the print method with string argument, it always works. Finally, I wrote a function which works fine. I hope ...

float conversion

Hi,

I tried to find a function which convert float to string, but all the know functions (sprintf, ...) are not supported by Z-Uno. Any idea?
