Re: PIC18F25K22 UART ERROR

Hi Bad day today..... but then I went to Evil Lab :) Not that great an improvement however as it appears that my tried-n-trusted multi-programmer EB-006 board is feeling it's age..... I used it to be the receiever but I couldn't get a repeatable response of "1" during initialisation (NRF m...

Re: PIC18F25K22 UART ERROR

Hi Tried the example Rx code (changing target) and I got similar to above on my analyser. Off hand I think the only initialisation difference was flushing respective buffers, but can't say for certain as I was in a rush. When I next get a chance I'll try and get both talking to each other. Not certa...

Re: PIC18F25K22 UART ERROR

Hi Okay, things going better (they always do if there is the prospect of beer at the end of task). Got my connections sorted and I can now get a reply from the module. From the documentation I noticed that Data is valid on clock leading edge but my analyser had it on trailing. Obviously this makes a...

Re: PIC18F25K22 UART ERROR

Hi

There are NRF24L01 and NRF24L01+ devices out there and it isn't always clear which is which. There appears to be some difference in registers but I haven't yet had time to go through things to see if any difference is significant.

I think the component is for the former.

Re: PIC18F25K22 UART ERROR

Hi

Found connection details and for ease I've designed a little breakout board which I hope to make tomorrow to continue testing. I've looked through the source code and will better understand what's happening when I try again.

Re: PIC18F25K22 UART ERROR

Hi

I'm hoping to have some free time tomorrow and hope to investigate further. I do need to find out reliable connection details for my module (with antenna) though.

Re: Macro not found in interrupt properties??

Hi

I created a blank chart using your chip and then a Macro.

Appears to work for me.

Re: PIC18F25K22 UART ERROR

Hi I was running out of time today so couldn't investigate much but I think it is component related. The Tx example runs and provides updates via the UART port. On it I see:- Start 0 (the failed transceiver init) 0 - 0 1 - 0 2 - 0 3 - 0 etc This is the "count" increasing and being sent out...

Re: Macro not found??

Hi

I've just tested with a PIC16F18877 and creating the Macro first and then selecting it in the Interrupt works fine as does creating a new macro from within the Interupt Properties.

What chip are you using? Is it an old chart you are "upgrading"?

Re: PIC18F25K22 UART ERROR

Hi

Not had much luck. I used a PIC16F18877 with internal clock but I'm getting some strange stuff on MOSI.

Can't find my documentation for the transceiver so unsure which pin is which.

I'll update when I get a chance.

Regards
