Re: rs-485
Thanks Jerry, I'll look at getting some q43 parts and get them working in the current project. I'm feeling bad about not starting this as a new thread. is there a specific website dedicater to umc? do i need to add anything to the swordfsh code to "use"/skip over the bootloader? Thanks again Rich

Re: rs-485
Great I might try this next year
PS any suggestions for a bootloader for either of these parts for internal osc at 64MHz? for rs232...
Thanks again Jerry

Re: rs-485
i will look t that part as i have a board that has an 18f26k22 and possibly looks pin compatible. unfortunately the main board that i wanted to add rs485 has an older 18f6723 which is 64 pins and i cant seem to find any q parts with that many pins. i have to say i find the microchip website just so ...

Re: rs-485
Thanks Jerry
Good call on the Q series parts.
I think i'll put up with the delay for now but i will look to see if i can swap in a q series part at some stage.

rs-485
Hi I don't know if anyone has a simple fix for this but I have just started using rs-485 and don't have much experience with it. I wanted to add this to an existing project, and i was just planning on setting the DE/_RE signal manually just before sending and setting low after sending but it seems t...

Re: HPWM/HPWM2/HPWM3 hardware PWM modules
thanks for the reply, its odd as it implies in datasheet that it's double buffered. Anyway the method I used definitely works all the time correctly on this specific pic, as i can trigger the scope on the analogue voltage glitch .
I just thought i would report it in case anyone else has this problem.

I have noticed the normal duty sub glitches periodically but my example code when using duty2 sub seems to work correctly. the pink trace is the tp signal yellow the pwm switched op light blue the voltage out of the psu.

Re: HPWM/HPWM2/HPWM3 hardware PWM modules
ok so seconds after posting i thought i'd try changing to c.0 as the output and that worked....
but only after adding
to the end of the program
also a.1 and a.0 worked.
thanks again Jerry.
but only after adding
Code: Select all
while true
wend
also a.1 and a.0 worked.
thanks again Jerry.

Re: HPWM/HPWM2/HPWM3 hardware PWM modules
ok so it compiles , but doesnt output anything . i tried to do an led test to check it was all working and noticed some of the other pins don't work as normal outputs. Device = 18F06Q41 Clock = 64 Config FEXTOSC = OFF, // Oscillator not enabled RSTOSC = HFINTOSC_64MHZ,// HFINTOSC with HFFRQ = 64 MHz...

Re: HPWM/HPWM2/HPWM3 hardware PWM modules
just a quicky i have just tried this with an 18F06Q41 and immediately throws a pin error
"invalid Hpwm_pin selection for 18f06q41.
has anyone tried this part with pwm and do you have a known working config.

Re: Any thoughts on q41 parts?
Great that worked.
and even managed to get the internal ref to work.
BTW the noise on the ADC seems low at 1or2 counts and no big offset like the k80 pics
This is starting to look like a very flexible small part.
Thanks again Jerry

Re: Any thoughts on q41 parts?
I hate to ask again but is there anything obvious i need to do to get the adc working in the 06q41 part, i see the adc is very different and have tried setting some of the registers manually but i just read zeros, and there are 45 pages to do with the adc!!!

Re: Any thoughts on q41 parts?
Argh!!! so after unplugging the programmer the led flashing started again. it seems that after upgrading the ipe to allow for programming 18f06q41's the programmer forgot i wanted to leave the pic out of reset, even after it supposedly had used "previous setting" from a previous installation. Thanks...
