Re: Programming a 16f628A

I'm glad it's not just me. And as I said there's an easy workaround. It doesn't appear to be any particular configuration and I get slightly different results with various chips of the same type. Looking at the circuit doesn't give any clues and it works ok every time with a 18f4550,16f877a and 16f8...

Re: Programming a 16f628A

Hi,

Thanks for your efforts. This is a problem I can live with as I can still program the chips but it seems strange. I have the matrix power supply and it's set to 13.5V. I'm thinking it might be some sort of decoupling problem??? Time to get the scope out I think.

Cheers.

Re: Programming a 16f628A

Hi,

loaded your program but it was set to 16f84. Sorry I should have posted the version set to 16f628A. Ran config autodetect to set it to 16f628a and set for XTAL operation. Still the same.

Thanks.

Re: Programming a 16f628A

Hi John, The problem I'm having is with all flowchart programs on this chip. For example a loop with a delay turning on and off a led at 100ms intervals. If I set the board to slow/RC then it will program the chip with no errors and the program will run as expected when switched to XTAL. But if I tr...

Programming a 16f628A

Hi, I'm using an E-blocks programmer EB-006. I can only seem to be able to program the chip with the osc switches set to slow/RC. If I set it to XTAL and fast I get a message saying the chip hasn't been erased and programming failed. Once programmed I can set the switch to XTAL and the code will run...
