    enc28j60 proteus simulation failed on CLKRDY check

    I've found, it's a timing issue. When I compile my prog for 8MHz (HS Mode) and run the simulation at 8MHz, it's ok. My original config, PLLx4 Mode and a Fosc=40 MHz, doesn't work. Seems the ENC28J60 model from Proteus doesn't want the 10MHz SPI, like the old revison of this ic.

    enc28j60 proteus simulation failed on CLKRDY check

    Hi I've made a simple design with a PIC18F452 and a ENC28J60. I use CCS C 4.140 and the CCS TCPIP stack. On simulation with Proteus 8 SP2, I've a problem in the MacInit () function, the check of CLKRDY bit always fail. I can see spi signals from PIC with oscillo in the reading of ESTAT reg...

    Help for identify SMD transistor.

    Thx Keith, I can't take photo for the moment. Why do you say 4 digits is unusual ?

    Help for identify SMD transistor.

    Thank you for your reply and sorry for double post. I've desolder one of these transistors. I can say now it's a SOT-23 package (L= 3mm). Thanks.

    Help for identify SMD transistor.

    Hi all. After several hours on Google, I couldn't find any informations on a SMD transistor marked "NHR8", in SOT-323 (or 23) package. Someone's got some specs or type for this transistor ? Thank You.
