Hello, I implemented the programmer based on the designs and it works flawlessly with a PIC 18F2550 and a 18F1320. The thing is that i tried to program a 16F628A that should be compatible, although it is properly detected it doesn't write any data to it. When i read it i get a repeated pattern : FF 3F FF 3F. I tried the same pic with a old serial programmer and it is written without a problem so it is not a pic problem I tried both the latest stable as well as the latest devel firmware/software. Is the functionality for this model broken in the latest versions? Can somebody verify? |

Dear Nick, The 16F628A PIC does work with the current software / firmware, although this pic is very selective when it comes to operating voltages. Please verify that VDD > 4.5V and VPP >13V with the pic connected.

Hello Frans, Thanks for your quick reply i'll double check the voltages but i think that VPP is 11.4 to 12.3 when i try the I/O test function in the software, i'll connect the programmer with the pic and check with a multimeter and the I/O test function.

The io_test function is good for an indication, but not very accurate in voltage. Using a multimeter is a better option.

Hello Frans, I measured the voltage between VPP and GND using a multimeter in the pic pins, it is 12.21V. I assume that this is not enough for programing the 628A?

Hello Nick,<br>
<br>
The voltage is on the low side. For this reason, in the new
schematic, D4 has been replaced by a 0R resistor (or a wire). Have
you also measured VDD?<br>
<br>
Kind regards,<br>
<br>

Hello Frans, Probably you didn't receive my previous e-mail due to the attached picture, VDD is almost perfect 5V if i remember correctly. Can i change the D4 on my current board without any other side effects or there are more changes needed ? I printed a board based on your through hole schematics so if there are more changes involved probably there will be difficult to implement.

Yes you can just replace D4 with a wire, there are no problems if you do that. Also it is smart to replace the diode which is in series with VDD with a low drop shottky diode.

Do you have any specific model for the VDD diode to propose? Something like 1N5822RL or 1N5817 will be acceptable?

I use the MBRL0520 (500mA, 300mV Vf) I don't know any equivalent through hole version but you can probably find it yourself. If you are not using an external power supply for your target chip, you can also just short the diode.

Hello Frans, I implemented all the changes as per you instructions, now VDD = 4.97V and VPP=12.82V.
