I have downloaded AN2250, which was written in CW for the DP256. I converted and compiled it under gcc3.6. I am trying to generate pwm audio on PWM4, using...
Hi, Take care of watchdog: if debugging disable the watchdog. Do you use nested interrupts? Also, you can watch variables in the second debug window: add them...
Hi, From what you write, it seems to me you have a wrong connection: The output pin should go first to a 47K resistor and then to the capacitor to gnd. The...
Yeah, looks like RC input is swapped with output. And regarding PMW/TIM routing. Nigel, did you see MODRR register in the docs? C family allows to route...
Aargh! I can't believe I did that! You are right. I started drawing it with input from the left, coming from a DAC. When I changed to the PWM, it was coming...
Yes, MODRR is clear (untouched) but the problem is with the R/C network, see my previous post. If if I had set the bit in MODRR, the doc says it should be...
Thanks! You are right, C-family MODRR routing isn't switching PWM from PTP to PTT. PWM are always outputed to PTP. Using MODRR PWMs can be gated and doubled on...
... I have posted it as PWM_tone_gen.zip. There is all sorts of experimental stuff in there you can take out, but the PWM part works on PP4 cheers, Nigel...
Hi Joel, I had a similar issue with the P&E USB BDM failing and losing synchronization etc, while the old parallel BDM worked fine. It turned out to be an...
Thanks, David ! Unfortunately, the PC I use is a laptop (because I've to flash "on site"), so I can't add an USB port, just USB Hub... So, for the moment, I...
Freescale really has nothing to do with that, and I am surprised that they did not refer you to P&E. You should enter a support request with P&E - they will...
Considering I paid a large amount of money to Freescale to purchase CodeWarrior, and the BDM also was supplied by Freescale, I would have thought that they...
hello, whos period? do you ask about baud rate? ly_haw <ly_haw@...> a écrit : Hi, May I know how long a delay needed between each transmission by using ...
Hi, For RS232 transmission, is that we need to have a delay for each byte we transfer? If yes, then how long should the delay be? Thanks for reply. yeehaw...
No specific problem for RS-232... It's very easy. It's a asynchronous protocol, so the receiver wait for - a start bit (always one start bit, low), - then 8...
... I vote for No - no delays are needed. But I don't understand why you are asking this, what's context? Is the other end of RS232 cable unable to handle fast...
Yeehaw, you don't have to create any delay, the communication is handled by the MPU, you just have to monitor the status registers Benny ... *RTS development...
... Few loose ends here, assuming you use modern gear, the actual serial protocol is handled by the hardware, you just have to watch the flags. The problem is...
For what its worth, I submitted this thread to P&E Support. I'll tell you if anything comes of it. In my experience, P&E has always fixed issues like this,...
The issue appears to be a timing issue with the the dual core AMD64 processors and the USB bus. It could be the USB driver, as the added USB board had a...
Hi all, I am just upgrading a product and will for only the second time use the PLL. In the first instance, the clock was only multiplied up from 8MHz to...
This isn't going to help but as an aside I've never been able to debug with the pll in operation. If I need to do source level debugging (techarts bdm with...
Hi All, I have successfully use the PLL while debugging with the PE-USB Multilink Interface(BDM). The PLL can only be set up in multiple of the base clock....
