thanks for that, what is "Emulated EEPROM in Flash" ?
Adding an external chip would require re-spinning the pcb. I thought about using WRITECODE and that might work but I worry about the endurance as I would like to write many times.
Hi Henrik
so I am aware of WRITECODE (have never used it) but the endurance on the original part 16F15376 will not suffice
on the 16F1937 which has DataEE HEF and will drop on the same footprint...
So I was writing to EE when I started to worry about the endurance of the EE as there would be frequently writes potentially.
As I pursued that in the data sheet without much luck I accidentally...
Can I use the PBP3 EE commands READ and WRITE on chips with HEF? I.e. are there any compatibility issues or DEFINEs needed ?
thanks for that BREAK idea tumbleweed
"transceiver" is just the term for the driver chip, i only use in one direction
there is an extension of the protocol that allows for a response from the light, i don't know how widely used that is...
well now you've done it Henrik
i was just warming up to the idea of doing everything in a polled loop and carefully squeezing activities in
re DT-Ints when you say "soft timing" do you mean...
it almost makes want to think about external hardware UART that has a 512 or 1k buffer, but i guess getting the data into that would be an issue too
are there such things ?
incredibly helpful!, thanks so much again Henrik
want a job ? :)
yes, DMX
Jeff did it for me many years ago @4MHz, but it was 100% assembler, i don't think picbasic was around then
and there was much less other stuff to do on that one than this new one which...
at the moment this is good, i am just roughing in some rough estimates for various parts of the overall program loop
at this stage whether it is 5 vs 6 shouldn't matter, 20 vs 5 or 6 might
...
just what i needed to know, thanks and hello again Henrik
so if i had 4 pairs of lines like above inside the loop (different pins) then i would have
6 * 4 = 24 cycles
24 + 2 = 26 cycles
26 *...
Hello all
'how many clock cycles for the two lines inside the LOOP?
DEFINE OSC 32
' chip is 16F1939, 8MHz xtal 4X PLL = 32MHz clock
OutputPin1 var PORTD.0

great stuff H & T thanks for the info
i need to learn more about handling the MSSP hardware directly as you are showing
Hi astouffer, this project is still alive for me!
i run the main loop at 8Mhz RC clock
when i call a gosub to do the SMBus via I2CREAD I2CWRITE in the gosub at the top i switch to 2MHz RC OSC on...
thanks bogdan, i did not know about that but now i see the section over there, do you use it ?
there seems to be a range of Proteus products, which one do i need to purchase ?
the sch side...
Hi, can anyone give me a jumpstart primer on doing simulation for PBP3 ?
i downloaded the OshOnSoft PIC16 IDE eval and gave it a very quick spin, modified a real program to run to a certain early...
wow, thanks a lot Alain
this exactly what i was hoping for
i got it to compile fine using PBP 3.0.7.4 and MPASM 5.49
i won't know if it works for about a week when the hardware is ready
as...
Hi all
amazing how fast the rust grows when you put this stuff down for a little bit
i thought for sure there was a PBP high level command for PWM that would do 10 bit, but it seems not, just...
i haven't used BJT's for ages, i would go with discrete mosfets as there is virtually no static gate drive current requirement (dynamic is another issue) and modern mosfets have near zero conduction...
yes agreed
i have asked MeLabs for help several times lately and always have gotten patient and useful responses, great company, great product
what program do you use with the PicKit2 to program chips ?
i have a buddy who does this stuff in C and uses MPLAB programming environment to program the chips but it makes you compile every time...
my recollection is that for low voltage programming you have to program it for that before you can program it with your code
also that there may have been other issues or difficulties, are either...
right, this is why we need to wave the flag and beat the drums about how fast PBP3 executes and how easy to use PBP3 is,
people hear 'basic' and they get all snooty
but i guess there is also some...
