  • View SPI signals in SPI Simulation's LA
    Hello everyone, I want to see SPI MOSI and SCK signals in Simulation's LA but I got nothing. The VTREG SPI1_OUT change to desired value but nothing is shown in LA. Any solution? Thanks...
  • SPI Clock issue of SPI with LPC2378
    Dear Sir, On Simulation a proper SPI clock is generated but in actual noisy clock is observed on CRO 1)Clock signal should be in square wave form? So if so for what reason noisy clock is seen on CRO...
