Re: Spontaneous Reset after Setting Bit on IO Port

Try adding a resistor, 47 to 100 ohms, in series with the MOSFET gate to decouple the gate capacitance from the processor output. Connect it between the pulldown resistor and gate. I have also seen the start-up step phenomenon you described. When driving an inductive load, like your relay coil, I sa...

Been fighting with communicating with a serial LCD. The LCD generates an XOFF char when expected. The MOD5213 seems to ignore it and over-runs the LCD buffer. Early in main, before anything is sent to the LCD, I set the following: InitIRQUart( 1, 115200, 1, 8, eParityNone ); IRQ_TX_XON_Flow( 1, TRUE...
