ignore this post I've found an error in the table (256) I have a cdata table in my program. It has 360 entries (indeed, full circle). I preceded it with an Org statement just to be sure Now something very strange happend. When I read the .lst file I see what I think is some kind of anomaly CData 234,235,236,237 ;60 CData 238,239,241,242...

You guessed right. I found out that HBUS would never be fast enough. And I'm back at where I started from: an 8 bit R/2R network. It will be buffered (MCP6001) and, probably, be filtered too. I just measured the max frequency (toggle at every pass of 360 bytes) and it comes to slightly over 3kHz. The uC is running at the max for this device:...

18F26J50 and 18F26K53 as Hosts?

In the webpage here for appnote AN1212 "Using USB Keyboard with an Embedded Host" I see that 18F26J50 and 18F26J53 are listed as applicable Pic devices but nothing in either datasheet would indicate that those devices were Host (as opposed to Device) capable. Is this just an error or is there some explanation? Anyone?

If the keyboard is the USB "slave", then the PIC they are talking about must be a Host. It looks to me that the app note says these devices can act as Hosts and thus control the keyboard. I bought a little gadget which converts a USB keyboard to two SPI signals, clock and data, works a treat and it costs the same as half a pint of beer. But...

Hi, I have 16 ir leds to drive. The issue is I want as part of the development to have a adjustment of the brightness as I could flood the receivers. The part is https://datasheet.lcsc.com/szlcsc/Everlight-Elec-IR17-21C-TR8_C131250.pdf My supply V is either 12v or 5v. My system uses a number of boards talking back to a main controller. I...

For the initial test I would consider 4 lines of 4 in series / parallel and an LM317 in constant current mode. If you want PIC control over the intensity then a PIC with an internal op-amp followed by a MosFET. just search for constant current. There was an LCD back light circuit I used previously that used a switching regulator and...

Hi Friends, A very interesting project has come my way. A company is putting up a RGB LED lighting system on a river-bridge which would be viewed from a distance of about 2 kilometers from an entertainment park on the riverbank. After sundown a light & sound show is being planned in the park.....the colorful lights on the bridge would start...

Hi Les and all I have a problem with the variable allocation of this processor. If I write: HSerOut the response at serial line is "Lu 18 Ma 2000 68:68:00" , wrong and unchanged, even if I change the value of Anno, Ore, Minuti and Secondi. If I write: g = Giorno a = Anno h = Ore m = Minuti

Thanks for the suggestions. Today I hope find some time to declare some variable heap to avoid the overlapping problems. But I want understand: the problem is only if my variable cross from bank0 to bank1 or in general crossing any banks? About the second issue (print cstr): is better create a new post? For me the problem is similar, and it's...

Thanks Toley,

I will store it away for safe keeping.

Fanie I thought you knew it was a library that Tim created.
