I am trying to slot a particle into an SPI connection between my hot tub control panel and its main board. My end goal is to remotely monitor and control my hot tub.
I used me Open Bench Logic sniffer to analyze the signal.
The 3 bytes take 400 microseconds to transmit.
If I use the SPI interface with the setClockDivider set to the max the slowest I can transmit the data is 100 microseconds on the SPI interface or 200 microseconds on the SPI1 interface.
Does any one know how to slow either of these interfaces ?
Is there a bit-blaster SPI implementation that I could run slower ?
