The Attiny4313 will be reading the output from some Reed Switches, IR Proximity Sensors and then send it to an MRF24J40, Arduino Ethernet which then sends info to a PHP Form-mail Script for emailing out.
The other MRF24J40 Module is connected to a CP2102 USB-TTL module and all i get is junk, However when I upload the code to an arduino (both 168 & 328p) the data is readable. I have checked the Baud Rate on the Attiny4313 (MRF24J40 must be set @ 9600).
I also have a pair of APC200's & APC220's and an old pair of GP-Gc010/CY2196R and will be pulling them out of their homes to test with the Attiny4313 but if i'm getting junk @ 9600 then I don't see how a faster rate of 19200 will make a difference.
I have read somewhere that the internal Oscillators can be inaccurate and may need tuning on the Attiny mcu's.
My questions are:
Will an 8 or 16 MHZ Crystal or Resonator to correct this(send data rather than junk)?
Can an Attiny4313 withe this configuration be used with the Arduino IDE?
