Re: PIC18F25K22 UART ERROR

Hi

I was made some tests with below code ,but I have no data to UART . Is there an error at code , or at component for NRF ?
Is it possible to send data with that transceiver ? Some projects with NRF works , but mainly with arduino . I can't use that
because of pcb space.

Regards

Basil

Re: PIC18F25K22 UART ERROR

Hi I was made some connector adaptor for NRF24L01 . I was used a general purpose PCB as it seems in photo, to connect NRF on breadboard. It was easy , but we must be careful to cut PCB cooper around 8pin connector of NRF. I will use those adaptors to test codes when there is communication between tw...

Re: PIC18F25K22 UART ERROR

Hi,
I get some new NRF24L01 ,and make some breakouts to connect transceiver to breadboard . I'll make some tests with PIC18F23K22 . i would like to know if NRF24L01 component works..For that I'll use my oscilloscope that can decode SPI data.
Many thanks in advance for your help.

Regards

Basil

Re: PIC18F25K22 UART ERROR

Hi, Tomorrow I'll get a new pair of NRF24L01 to test the component using NRFTest example for Tx /Rx . I'll use PIC18F25K22 that I have. In the meantime, maybe Matrix should do a check of NRF24L01 component , or should it first be confirmed that the NRF24L01 not work ? Maybe to set another post for c...

Re: PIC18F25K22 UART ERROR

Hi I was tested TX-RX pairs with no result.. I noticed that have no current when I connect power to NRF24L01/PIC at both transmitter / receiver hardware. I can't find something wrong in circuit , but why not work the NRF ?...Maybe RF modules are defect .. I would like, if you can ,to test RX/TX circ...

Re: PIC18F25K22 UART ERROR

Hi,
You've right about A.3, I didn't noticed that...Tomorrow I'll make corrections and test the code for receiver/transmitter.
About programmer for PIC, I was found solution , so I'm ready for programming.
Many thanks.

Regards

Re: PIC18F25K22 UART ERROR

Hi, I made some corrections to hardware according to previous schematics . After that I was tried to programming PiC for transmitter/receiver...programming PIC12F1822 with PICKIT3 ok..PIC16F18313 not support by PICKIT3 , so I get a new PICKIT5 .Using MPLAB X v.6.20 , I have no connect with PIC...Con...

Re: PIC18F25K22 UART ERROR

Hi,
I hope that is the last update ..I use SS in both pair. Something for that I'm confused ,is connection MOSI, MISO between PIC and NRF...The correct is MISO-----MISO /
MOSI------MOSI or MOSI------MISO / MISO------MOSI ?
I've seen both connections ways in many examples.

Re: PIC18F25K22 UART ERROR

Hi, Thanks for info. I'll make corrections to hardware and test if it works. The demo codes that I was posted for first converter (AN to SPI / SPI to AN ) is ok (except of course of pin connections ) ? so after selection of PIC and pin remapping at properties , to make some tests. I think that there...

Re: PIC18F25K22 UART ERROR

Hi, First the Scotland sun !! The job can wait.. The problem is that I need an extra pin for Analog input for transmitter and a DAC OUT for receiver ..so, I'll try to retain PIC12F1822 at transmitter changing the connections as follows Transmitter PIC12F1822 NRF24LO1 A.0 MOSI A.2 MISO A.1 SCK A.3 CS...
