Addictive Tools
Of the many tools I have used in the recent years, while working on various embedded control projects, there is one that I have quickly learned to love: the INTRONIX Logic Port. Now I am sure you have seen and … Continue reading
The Big I2C SEE Table
Not all I2C Serial EEPROMs are created equal. In fact there is a lot of variety out there as the memory size increases the addressing schemes change, the number and use of the device select pins change as well. The … Continue reading
I2C Interface to Serial EEPROMS (continued)
In a few previous postings we started exploring the I2C interface and in particular its use to access the most common and inexpensive type of Serial EEPROMs (24xxx). After the long preamble, it is about time to start talking about … Continue reading
I2C Interface to Serial EEPROMs (continued)
In two previous postings (Chapter 7 1/2, I2C Interface) we have started looking into the I2C interface, some of its applications and the very basics of the communication protocol. It’s time to start sending and receiving data bytes and learn … Continue reading
Of Explorer 16 boards and 5V LCD displays…
I read with interest today an errata for the Explorer16 demonstration board… I know, it seems strange to think of an errata for a demonstration board, but it can happen and as in this case, there is a good lesson … Continue reading
I2C Interface (continued)
The I2C bus is based on a very simple protocol, a small set of rules that dictate how the two lines SDA and SCL are supposed to operate to allow the transfer of data. With the premise that, at idle, … Continue reading
Chapter 7-1/2 The I2C Interface
Over the last year I have received a couple of emails from readers inquiring about the absence of examples on the use of the I2C(tm) synchronous serial ports of the PIC24. I imagine many more of you would have liked … Continue reading
Having Fun Prototyping Lately?
PICTail(tm) Plus is the name that Microchip uses for the expansion socket offered by the Explorer16 boards. It is one of the easiest and most flexible options available for prototyping out there. All the signals from a 100 pin PIC … Continue reading
