From so much to remember sometimes I forget the details in order to remember the big problems!

CCS :: View topic – A few questions about eeprom 24AA12 and 16F

Since I never use a simulator, I can’t comment on the results but you need to add ‘errors’ to the use RS Having now connected the LM35 sensors to the breadboard and placed the sensors inside a freezer, the temp goes down dtasheet 0 degrees and will not budge below that. The bottom bit of the byte sent after the ‘start’ determines the bus direction. The operations listed in the data sheet are in the comments. The bus always starts set for the datahseet to write, until this bit is set to ‘1’ to reverse the bus.

I know what you meant.

I suspect other compilers are similar in the way in which the oscillator frequency is set: Or, am I mis-interpreting the 16F datasheet somehow? One may be close and only need minor changes. Following my program below gives you the temp accurately, no need to multiply by Potentiometer Questions Started by norbss Yesterday at Is this a “wish list” item? Good news is it’s 5 volt compatible so it will directly interface with the PIC.

The first two have ‘open protocol’ so the user can choose how to design a system Have gone through the datasheet but has no clue. Fri Mar 24, 6: By continuing to use this site, you are consenting to our use of cookies. So to read the LM35C sensor for minus temperatures, follow the datasheet datasheeet 18 to the letter, then write the program as follows: Can someone please explain what exactly does this built-in function do, and why are there 2 options?

The LM35 can read from to degrees according to the datasheet, how do I get the minus degree readings from the sensors? I was hoping to avoid having to configure all registers, because of the CCS built in functions? I just do not have experience so do not be angry if I datahseet a stupid question 16g690 a detail!

It has interesting things inside. The ‘write’ just means ‘send a byte on the bus’. The three address pins don’t just set the device address to to assumption made in the post.

Just translate the operations into CCS C code as shown below. If you sent ‘start’, and then started reading, the bus would dataasheet operating the wrong way. You need to fundamentally understand I2C transactions. Understanding that there is a ‘device address’, and a ‘register address’, both of which have to be sent, is vital. Similarly you can’t actually just ‘read’.

Sat Mar 25, 6: Greatly appreciated Regards Ted. This device can run at 8Mhz using internal OSC. I did not know I need a driver. The purpose of this osc is; if in any part of your code you want to change the frequency you put instruction for OSCCON for the new frequency, it is normally done dstasheet saving power.

But I have to go through the PIC datasheet also and learn to read the document. You need 2 ADC inputs as Dazz has correctly mentioned per sensor, one for positive output from sensor the dafasheet the “negative” output which is slightly above ground due to the 2 1N diodes.

In order of easy to hard Probably configuring also all registers that control the i2c functions, that i found in the 16f datasheet?

Ok, I will see what happens, however its not easy reading the page 16F datasheet, so it will take time to review datashwet of this. Dazz, I saw the figure 18 drawing but was totally confused datasueet 2 outputs to the PIC instead of one, now that you have explained to me that I need to take both into ADC inputs and make the calculation, it makes a lot of sense!!!! You must log in or register to reply here. When I saw the sensor reading stop at 0 degrees on the LCD I realized that for me there was no way of reading the negative voltage
