Re: App Developer - Text Array / Values Table

Ah... yeah. Mostly I thinking for PC developer. Which may be on a different development path to Web Dev. J.

Re: App Developer - Text Array / Values Table

Hi, I noted from another post that App Dev may seen some more development soon, so a cheeky bump for this idea.
A simple user defined array of textboxes, x Columns * Y Rows.
With a macro that populates each cell with a text string or value.

Re: C Based Delay - with and Without Timers

Yeah, I'm definatly staying within standard FC as much as I can. I'm an engineer, certainly no coder! Sadly the single Hardware UART is being used to drive a LIN output. J.

Re: C Based Delay - with and Without Timers

Well, I still can't get any Software driven UART type to send out anything with the correct Bit timing for 19200 or above. I would have though a PIC running at 32MHz should have been able to do that? Running in HS PLL mode is painful since I'm not sure if the FC internal delays/timers/calculations k...

Re: C Based Delay - with and Without Timers

I'm going down this rabbit hole a bit further to improve my understanding and I 'think' I'm getting there! This needs two instuction cycles, which may explain the larger value I got previously. LATC6 = 1; NOP(); LATC6 = 0; I think this is closer to a single instruction delay and is my TRUE minimum p...

Re: C Based Delay - with and Without Timers

Hi, Thanks Martin, Leigh, As you both stated the method used signiicantly effects the duration of very short pulses. A) toggling single bit of Port C, using the FC output command and delay using a single NOP(); in a C code box. Result a Pulse of : 998nS B) toggling a bit using "LATC6" and ...

Re: C Based Delay - with and Without Timers

Thanks Steve, I got 1uS (998ns) on a single "NOP();" so there is potentially something funky going on. J.

C Based Delay - with and Without Timers

Hi, Side task whilst debugging my test rig. :) How can I create a micro second delay in C code. I wish to avoid the FC Delay function, to exclude that from my investigation. A) One method that uses the PIC timer. B) Second method that avoid the using Timers. Maybe a known loop count of 100 or simila...

Re: FC11 Software UART Bit Timing?

Hi Ben, Please move this to another Forum section if its no longer a bug issue. thanks, J. FOsc 20MHz, HS Mode. No PLL. I'm 95% sure clock is correct as this also clocks the hardware UART with No issues. I measure these values on the scope when using the Hardware UART. All of these Work Great and ar...

Re: UART Baud and Bit rate Measurement With a scope.

Thanks for the clarification Leigh! exactly what I needed.

Fair Point regarding the question, everything is down to interpretation.
I asked "when measuring UART baud rate with an oscilloscope do you measure the period or pulse width"
hey ho. :) J.
