Frost Protection Collaboration with UC Davis

Frost Protection Collaboration UC DavisiP Solu­tions is col­lab­o­rat­ing with the Bio­me­te­o­rol­ogy and Atmos­pheric Sci­ence depart­ments of U.C. Davis on a frost pro­tec­tion mon­i­tor­ing sys­tem.  A sys­tem pro­vided by iP Solu­tions has just been installed at the UC Davis Camp­bell test site.  Tem­per­a­ture and humid­ity data cor­rec­tion is cur­rently being conducted.


SPI Command-line Utility for Raspberry Pi

Raspberry PiiP Solu­tions has cre­ated a Ser­ial Periph­eral Inter­face (SPI) command-line util­ity for the Rasp­berry Pi ( plat­form.  The util­ity, spincl, is licensed under Open Source GNU GPLv3 and is being offered by iP Solu­tions as a free down­load with source included.

Although a C library exists for the Broad­com bcm2835 with an SPI Appli­ca­tion Pro­gram­ming Inter­face (API) among other things, there are rea­sons to have a command-line util­ity, which can be invoked from a shell com­mand line or from within a script.  A command-line util­ity allows easy test­ing and debug­ging of SPI slave devices with­out hav­ing to develop a C exe­cutable.  Addi­tion­ally, it pro­vides a sim­ple way for bash and python scripts to access the SPI mas­ter of the BCM2835 on Rasp­berry Pi. Although the raspian dis­tri­b­u­tion pro­vides GPIO libraries with the included python instal­la­tion it doesn’t include an SPI library. spincl, on the other hand, can be invoked from a python (or bash) script.   Con­tinue read­ing

Raspberry Pi Weather Station

Raspberry Pi Weather StationiP Solu­tions has cre­ated a Rasp­berry Pi weather station. The Rasp­berry Pi plat­form employs a Debian Wheezy Linux dis­tri­b­u­tion.  iP Solu­tions designed and fab­ri­cated an ana­log and dig­i­tal I/O board to inter­face the Rasp­berry Pi to tem­per­a­ture, humid­ity, baro­met­ric pres­sure and wind-speed sen­sors.  Addi­tion­ally, iP Solu­tions cre­ated a sep­a­rate pro­pri­etary tem­per­a­ture and humid­ity sen­sor module.
