I was under the impression that MACs could emulate/run PC software these days ??
MACs are Intel-based for several years, It is possible to install Windows on it and have two OS in parallel. But not ...

Problem :
I can use SIOW for uploading *.hex to MCU but my customer with computer running OSX is not able to this.

I'm looking for a free App or a simple way in OSX which simulates the SIOW.exe, a ...

Yes I also noticed that it is not only happened for zero, but also all values between 0.0-1.0. For Values closer to zero like (1E-15, 1E-30, 1E-38) it takes longer and longer and the worst case is zer ...

if you test the highest exponent bit (bit 30 of the 32-bit float value). If it's zero, the converted integer value will be zero, too.

It works ! tnx for suggestion.However I found a solution and co ...

I faced to a problem in using Float_To_Int32 function, the problem is that converting a float variable or even float constant with value “0.0” takes 4 times longer than other values like 0.004, 0. ...

I noticed a longer verify time for 33FJ256MC710A than 33FJ256MC710 (old silicon revision) !

As I read the status of programing window after programming 33FJ256MC710, ICD-U64 only checks the CRC an ...

Actually the SOSCO pin is tied to a 74HC14 chip, I use this the clock for driving another parts of the circuit. The oscilloscope probe is connected to the output of 74HC14 so I don't think there would ...

O.K., that's another issue. PCD intends to set the bit, but the code is rubbish... .

That is pretty correct, because I read LPOSCEN again from that register address (0x742).
It returns 0 for setu ...

I forgot the lock setting, but there is no need for writing direct ASM commands because LPOSCEN was already configured in code via "setup_timer1(T1_EXTERNAL_RTC|TMR_DIV_BY_1)"

PCD C/ASM l ...

The manual requires to set LPOSCEN in OSCON. Did you?

For enabling LPOSCEN I added these lines, still with no hope!

#include <30F6014A.h>
#bit LPOSCEN=0x742.1

void main() ...

Hi

I cannot manage to run 32.768hz oscillator on SOSCI/SOSCO pins. a crystal with two 18pF caps and a 100K resistor are connected to RC13 and RC14 the same as Microchip suggestion "DS70143B-pa ...

Thanks PCM programmer It was done with a piece of wire .

if I set the timer to operate with internal oscillator it can reach to 10mhz freq when PIC run at 40Mhz .

I think an external clock with 1Mhz Freq can solve the problem ,but I dont have access to ...

Is it possible to run the Timer1 OSC with 1Mhz external crystal ? I see 18F reference and it suggested value in 32-200Khz range .

If yes what Capacitor value should I use for 1Mhz?

PIC=18f452 ,F ...

Hi there, can you perhaps send me the driver code you used for your interface .

The Code is so simple just calling the MMC_init() and read and write to blocks the problem is at basic functions .
