Hello

I've been working on this issue a couple of days but I'm still unable to solve it.

I'm convinced that the problem is in my computer. I've tested my device in another Windows 8.1 x64 machi ...

Hi Ttelmah. Thank you for your response.

I've been checking my hardware and I already have installed series resistor in each line as close as possible to the microcontroller. Mines are 33R. I've ...

Hello,

I've been developing a device for academic usage that uses a CDC bootloader. The application code also can communicate with USB.

The microcontroller used is PIC18F66J50. When in USB mode ...

Hello newguy.

I'm not storing data in the internal PIC memory. I use a 24LC512 external memory.
When data must be stored I disable all the interrupts in order to avoid problems in the timing of th ...

Hello everybody,

I'm using a PIC18F67J50 to measure temperature using thermistors.

First of all I calibrate the AD (a functionality of this PIC AD converter...)

My AD converter configurati ...

In a first time I though that was the problem and tried to check this...

But in the .SYM file I see this:

654 get_str.i
655 get_str.@SCRATCH1
656-659 @PRINTF_L32D_82FPFPF.P1
656-659 ...

Hello everybody

I've a function that configures the AD. It accepts as a parameter the channel to be converted. This function is called "Convierte_Canal"

float Convierte_Canal(char ...

My receiver only accept the frame in promiscuous mode

In both normal and promiscuous modes, packets are stored in the rxnormal buffer unless they have a bad CRC (page 106 in MRF24J40 datasheet). ...

I found a solution, after pulling up and down the WAKE pin, a RF reset is needed:

OUTPUT_HIGH(WAKE);
delay_ms(3); //delay of at least 2ms
OUTPUT_LOW(WAKE);

//Reset RF ...

Hello people in this forum¡

I'm working with the MRF24J40MA module, I communicate two devices, both PAN coordinator. One is the transmitter and the other the receiver. The communication works fine ...

Hello,

Is there anybody working with MRF24J40MA??

I'm working with a couple of MRF24J40MA and I have a question about the "Frame control Field" in the IEEE 802.15.4 packets.

Hello everybody,

I've solved the problem:

The correct fuse to configure the PLL is the
#FUSE H4_SW //High speed osc with SW enabled 4x PLL
then
#FUSES PLL2 //Divi ...

Hello everybody¡¡

I'm working with the 18F66J50 and the 18F87J50 PIC micros.

I'm trying to configure the USB at 48MHz and I've done this:

I use 8Mhz crystal ------> I need to convert it ...

Thank you very much bungee-

I've seen the ICSP application note, I didn't noticed that about the volts in the VPP pin, Embarassed

I will not use this pin as a digital input because I have no simple ...

Hello everybody in this forum¡¡

I'm programming a PIC18F4550 mcu...

In my application there isn't need of a reset signal so I plan to use this pin as a digital input:

pin nº 1 : MCLR/VPP ...
