Re: My PIC-based TV-B-Gone (design attached)

Post by coldkeyboard »

I have re-wired the board now but somehow it still doesn't work or I'm doing something wrong... I've tried it on 3 TVs and nothing.
Can someone with this PIC firmware check how long does it take to transmit all of the codes. Mine does it in about 1min 45sec.
I don't know if my IR LEDs are wrong or they don't get enough current or something else, I'm running out of ides and I'm becoming more and more
desperate to make this work :) Any help is greatly appreciated :)

Could you please tell me how did you manage to port the code from AVR to XC8?

Specifically I have a problem with struct that has flexible array inside it?

Code: Select all

// The structure of compressed code entries
struct IrCode {
  uint8_t timer_val;
  uint8_t numpairs;
  uint8_t bitcompression;
  uint16_t const *times;
  uint8_t codes[];     // <- this line get's me into trouble
};
I have to change it into uint8_t *codes; but then I have to rewrite the whole worldcodes.c file, which looks very very very painfull.

Any ideas on how to do it? Or if you could post the source/example on how did you solve this problem?
Thank you in advance! :)
