Bug on AS3935

Posted on March 22, 2013 by Skye Sweeney

After three weeks of banging my head against a brick wall, I confirmed last night that the AS3935 has an issue with the I2C interface. There is an issue with the chip that prevents reading register zero without violating the … Continue reading →

AS3935 and register zero

Posted on March 17, 2013 by Skye Sweeney

The more I bang my head against this chip, the more I am certain there are ‘issues’ with it. I can now read and write every register with amazing repeatability except register zero. This register refuses to be read or … Continue reading →

AS3935 lightning detector update

Posted on March 14, 2013 by Skye Sweeney

I was having problems with reliable communications with the lightning detector chip over the I2C bus. Sometimes I would read a register and it would not be at all what I was expecting. The situation was during calibration when I … Continue reading →

Another excercise in Yak Shaving

Posted on March 3, 2013 by Skye Sweeney

I have been having problems with the I2C interface on a chip I have been playing with. Since I do not have an I2C bus analyzer (nor can I afford one!), I have been using my scope to decode bus … Continue reading →

Posted on February 10, 2013 by Skye Sweeney

After a very frustrating weekend, I am pretty confident I have the worst of the integration problems behind me. The Embedded Adventures board is a very nice board but did take the choice of SPI or I2C out of my … Continue reading →

Posted on February 4, 2013 by Skye Sweeney

After ordering the break out board from Embedded Adventures in the UK, I got a nice email indicating that they would ship to me via stock held in the USA. The email also included some sample code for a PIC.

Lightning Detector

Posted on January 31, 2013 by Skye Sweeney

First I must apologize for going off line so long. Back in June I got a cold that damaged my inner ear. With the damage, I have been suffering from vertigo. Luckily, the brain learns and re-calibrates the inner ear … Continue reading →

Converting the lightning detector over to RS-485

Posted on August 29, 2011 by Skye Sweeney

During the precessing of getting the RS-232 communication working with the lightning detector and my Linux box, I learned the advantages of RS-485. RS-232 sends over its signals as a single ended voltage. RS-485 uses a differential signal. This has … Continue reading →
