hex file

[matthewt48]

Hi, could any one help me I made a hex file using flowcode compile to hex and tried to program it to a pic16f877A with the hex file that flowcode had generated. Using a universal programmer model SEEIT TOP3100 installing the hex file to the chip and this is so hit and miss to whether it works or not any help would be grateful

Hi

The programmer you are using is quite capable. Although I have little experience with it, it doesn't sound to me like a code issue, as if so there probably would be many posts regarding such.

Is it only hex generated by Flowcode that has issues or code generated by everything?
Have you tried downloading via any of the PICkit family (for example) just for comparison?
Can you download to any other chip successfully?

Sorry to ask, but this has caught me out more times than I would like, is your USB cable good? Also, are you powering it via USB or externally? I have heard of issues when powered by USB especially with a laptop.

Sorry I can't be of more help.

Regards

Hi, I tried using mplab ICD 3 and it worked. I found that I was getting errors from the compiler because I did not first compile to c and the to hex when I did this in the correct order it started to program OK. thank you so much for the reply it was very much appreciated, I am new to Flowcode and using VERSION 9.2 which seems to have a lot of upgrades compared to older versions that I try to follow on youtube
