Hello Unregistered ,
a bit out of practice , forgot porta.4 is input only plus 1827 has bits and pieces in other banks so tested and working version ...
For a 1827 it would look like this [untested] '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' ' Name : 16F1827 LCD BACKPACK ...
maybe the chip? for my part I used 12F683, 16F690 old regular Pic. I tried richard code, and it's impressive asm code, that I can't do for sure. so I stick to basic.
Tried different baud rate but still only Backlight work. The rest is just irrelevant characters on screen. Then tried the new code of Richards, but have 1827 chip, so asm code is not compatible. ...
here's the revised baud rate test chart 9998
ASM , very impressif code, thanks.
its always better to use the hardware than bit-banged routines and there is nothing better than a ring-buffer to overcome traffic snarls ...
there are some good ideas here https://www.romanblack.com/DTMF/DTMF_alg.htm
Plenty fast, I'd say. At 32MHz an instruction cycle is 125ns. That's ~1250 cycles between zero crossings. I'm not trying to interpret/decode the data, just demodulate the signal. Every other...
edited BaudR var word : baudr = 3313 and TRISA = 111110 1st receiving random characters 2nd normal what could be done to avoid the first thanks. 9997
