BASCOM-AVR : Temperature differences between two DS18B20 sensors. : NEWTOPIC
Hi there, I am using thermometer with ATmega88 and two DS18B20 sensors in multi node bus. The resolution is 0.1 °C and all work well except one unusual thing. I found a difference between the two...

First I would try what the sensors show when they are both in the same place.

I assume you are using 12-bit mode. I assume you are looking at the data readings before any rounding. They are spec'd to +/- 0.5 deg C at that temperature. You should test them with the sensors...

@Visovian and JC You're right I put them on the same point the difference has decreased, now it's about 0.2 - 0.4°C I think it's normal in this case. Thank's again for the reply.

Hello All, Can 'Data' be configured as a 2 o3 dimensional structure, with varying lengths of elements like this C code - which consists of constants and a structure: #define RF_POWER_UP 0x02, 0x01,...

Hi Tim, In my example the "Names" are just constants defined else where in the code. It just makes the code easier to read. It give it a unique Name just define a Label (Rx_structure: in this case)...

Hi Ian, That is exactly what I was getting at. Except I wanted to know if it could be expanded to a 'Data' type (I know it is is not a type, but for lack of a better word...). What they (HopeRF) did...

Hello, The data Statement just writes the following values to Flash without any "structure". As a programmer you'll have to create/define the structure of the Information yourself. In your example you...

OK, It did not look like there was any way to do that, this thread had code similarly from Dave, but I suppose just reaching for something clear, concise and simple. Thank you Ian and all, for your...

Hello Tim I would put this in eeprom The bytes stored in eeprom will line up with the variable so all I have done is dim the variables in order then load the data into eeprom you can see this in the...

Thanks Paul, Interesting idea, I will consider that option. Mark, MWS Thanks for the look inside bascom. Mostly over my head but very interesting. Dave

Devices like the Mega1284 also have Uarts with SPI mode it would be nice not to switch from SD card to Wiznet W5100 but Bascom does not support this yet. Regards Paul

Hello EDC Did you have a look at AN#196 where I used eeprom for character rom ? To leave space at the front of eeprom I would dim an eeprom variable eg I want 5 bytes of eeprom free When you dim eram...
