SD Card

howardmsmall #24469 Has anyone added an SD Card to their Raduino? If so, for what purpose, e.g., storing memory frequencies? Howard, VK4BS
Dennis Zabawa All Messages By This Member #24481 Why would you need an SD card when the Nano has 1K of EEPROM memory? ?You could store a reasonable number of frequencies and alpha tags in it.
howardmsmall #24518 From earlier posts I am led to believe that writing frequencies too often to the eeprom will shorten its life considerably. I had in mind the possibility of storing frequencies ad hoc which coukd then be too frequent. Howard, VK4BS

Dennis Zabawa All Messages By This Member #24522 The EEPROM in an Arduino is good for an average of 10,000 write cycles and virtually unlimited reads. ?If you only wrote to the EEPROM when you actually updated an entry, the board would probably outlast any one of us!
Terry Bendell #24525 I've been toying with the idea of removing the arduino and using a Raspberry Pi 3 to facilitate everything from mode/frequency changes to CAT control and internal digital programs like FLDIGI WSJTX etc. ?Seems a simple enough project. I use 32GB SD cards in my Pi's no shortage of space :)
howardmsmall #24526 Thanks for the info offer .I am a babe in the woods with the Arduino and put the post up to see if it is feasible before I try to learn how to do it with an SD Card. As it seems it may be OK to use the eeprom I will explore that first. I am hoping to find a way to store frequencies that can be recalled, maybe with a channel change switch? At this stage of my learning I am just having fun listening around and doing some simple sketch mods. Howard, VK4BS
Simon Rumble #24567 The Raspberry Pi wouldn't be able to do any of the timing tasks fast enough I'd expect. And there's no reason you couldn't do the CAT via the Arduino. Digital modes though, you could package a R Pi in with the BitX I suppose? toggle quoted message Show quoted text On Wed, 5 Apr 2017 at 09:34 Terry Bendell via Groups.Io <terry.bendell=[email protected]> wrote: I've been toying with the idea of removing the arduino and using a Raspberry Pi 3 to facilitate everything from mode/frequency changes to CAT control and internal digital programs like FLDIGI WSJTX etc.?

Pavel Milanes Costa #24594 开云体育 Hi. Adding cat is (almost) plug and play tech now (if you know how to code), see and it's examples, a working sketch on Cheers.
