Hi, I meet some problem of flash corruption. Is anybody know a method to read the flash contents of a P89LPC932A1FDH? Actually i program the microprocessor by...
You may use ICP to readout the flash CRC. Don't know about reading actual contents. Are you using an external crystal? I'm asking this because the flash in my...
Yes, i use external resonator. I will try to use an other way for external clocking. Thanks for your answer. David From: geejee_lpc Sent: Wednesday, December...
All, Does anybody know how I might contact Mr Bauke Siderius? I have taken version 1.6 of his software from the forum files section and intergrated it into a...
I think you want to read the program memory, you didn't specify this in your question. But, as I know, this is not possible. You could only read a 32-bit CRC...
Hi, I just can't seem to find information as to what the voltage reference value is for the SAR ADC used in several LPC9xx devices. It would be fair to assume...
Hi, I can't find any info about the ADC voltage reference for LPC915.. etc. I assume it must be the 1.23V internal ref but nowhere is this described , either...
Hi, the internal reference is derived from the supply voltage. There is no absolute voltage reference like the internal 1.23 (used for brown out) but the...
Hello.. I Try to setup CCU PWM unit in LPC936 but cant get it working. Timer 0/1 as pwm works great but I need more PWM's The unit is clocked with 18MHz...
Yes, make sure you have a pull up resistor on the PWM pin to VCC of the chip or it will not start PWM. Found this out the hard way. Typical value of 2.2K will...
Wrong, the push pull design is disabled in code to open drain. Check your code, don't believe that, use code architect to validate the result of the GPIO...
Hi everyone, I have a USB-ICP-LPC9XX programmer that I've used just a handful of times. I've got my own custom programming header soldered on to the end of the...
hi, have you succeeded in resolving the output high problem. I am interested in knowing. i face similar problem with 89vx2fn. help is highly appreciated. ...
Krishniah, I might be wrong but I do believe that ICP for the LPC900 is rather different from the ICP for the 89V5x devices. Did you try the NXP forum? ...
Mr. Bob, Thank you very much for the reply. I will try other forums. I have been trying invain, for a long time. Every time i met with failure. the system does...
Hi, check out Flash Magic. This tool supports pretty much all NXP Flash devices. http://www.flashmagictool.com/ It is free for personal use. and works through...
Bob, the P89V52X2 (where 'X' is part of the chip's name) is rather different from the P89V51Rx2 (where x='B','C','D'). It cannot be programmed through ISP...
Hi All From what I can see the P89V52X2 uses ICP (not ISP) and I believe that this is the same ICP as used in the LPC900 series. I have used with great success...
Hi, I am trying to implement P89LPV922 bootloader using IAP-lite. I've figured out that data programmed to the chip is wrong. Seems like the problem is not in...
Hi, as group moderator I will always do my best to keep the groups clean. When spam appeared in this group I deleted it and banned the spammer. It is not even...
