#167320 - Link to HMI board schematic Responding to: ???'s previous message |
Hello Konstantinos,
Please find the schematic here: http://www.8052.com/users/potluri/HMI_board.pdf You can also find the schematic at the flashmagictool.com link that I gave in my first post if you log in to the flashmagic forum with your user ID and password. Item 3 of the post at http://www.8052.com/forum/read/141973 says not to ground PSEN. We are not grounding the PSEN of P89V51RD2BN. I mentioned that in my post at flashmagictool.com. Thank you. |
