Hi, First unit to be repaired of a new design has been sent to me. As It's the first one, I'm more interesting in identifying what happened than in repairing it, in order to know if it's necessary to change something in HW or SW for future supplies or if it's ok as it is and it's just a common reparation. LPC2132 in the not working board is not starting up. If I debug using JTAG I can see th...

Hello, actually I'm working with the LPC2132 uC and with the development software uvision3 from Keil. I'd like to protect my source code by enabling the code read protection. Through the datasheet I know that I have to write the constant 0x87654321 to adress 0x1FC. When I look into the Flash after programming the uC(Code read protection isn't enabled yet) I can see that at the adress ...

hello; After a couple of year on PIC uCs ,recently I started working on LPC2132 Arm microcontroller.I use Keil Real View uc development kit to compile and H-JTAG to flash. I've compiled a few project and they worked well, however I couldn't figure out how to arrange startup.s file. I have been working on a simple uart program explaining in AN10369 paper. But, what i see at output is just...

Ok guys, I feel dumb asking y'all for help, but I am borderline going crazy. What I am trying to do is send numbers 0 through 20 over a serial cable to hyperterm (running on XP). I have the phillips lpc2132. I provided the code below. What I am not looking for a direct solution. I am looking for some hints for when this code may go wrong (why it isn't sending to hyperterm). ...

Hello, I am using a LPC2132 controller for a project. I need to update last event logs to non-volatile memory at least 300 times a day. To reduce cost, I am planning to use half of the the onchip program flash memory. However, I am concerned about longevity of this module, as 10K erase cycles gives us only 333 days of reliable memory. Actually, the data to be logged is not more than 256 b...

Hello, I am developing a LPC2132/01 based system. I just received the assembled PCBs and I tried to put in a test program. But the LPC2132 won't go into ISP mode. Pin P0.31 is left unconnected, and pin P0.14 is used exclusively for ISP mode select, with a pull-up of 10K. I used LPC Flash Utility v2.2.3, tried baud rates of 4800, 9600, 19200 and 38400 but none of them could detect the device ...

Hi folks, I am experiencing a strange situation: I recently purchased some LPC2134 parts; I added them to a board that I know to work (I usually put LPC2132 on it and they work without problems), so when I connect the flashmagic tool or the lpc2000 flash utility, i can not read the device id/device signature (and of course I can not program them). I checked with an osciloscope and the clock is ...

Hi! I have a problem using fractional baudrate divider on LPC2136. When i'm not using FDR i get baudrate (for example crystal is 14.318 MHz, PCLK = 14.318 MHz)FDR = 0x10, DLL = 0x10, DLM = 0x00. baudrate = 55930, error about 3% from 57600. Everything is seems to be ok, UART errors with this setting are very rare. But when i using FDR to set baudrate more accurately - FDR = 0xB8, DLL = 0x...

Hi buddies, I'm need to develop a full serial driver for the enhanced UART1 (LPC2136/01 device). This includes flow control, which can be softtware (XON/XOFF), hardware (RTS/CTS or DTR/DSR) or none. I have found many examples of simple uart drivers not using flow control but NONE using flow control. Can anyone may help me with this issue, since I have no idea how to write a serial dri...

Hi Group, I have built a code using LPC2136 & it runs successfully giving desired outputs.I have a problem reg. the entering of LPC in ISP mode when I switch on my board.I have made a circuitry for ISP giving 22k pull up on pin p0.41.When once I program my chip(giving logic 0 on pin p0.41 after reset-through u-link jumper-connected to 1K pull down resistor),the chip is programmed properly....

I'm having problems getting reliable UART receive operation at baudrates of 1mbit/sec & above. PCLK is 60MHz, and baudrate is definitely set correctly as verified by looking at TX data on scope, and the sent data is also correct ( coming from an FT232R). What seems to be happenning is that the UART gets into a state where it appears to be receiving data ( correct number of bytes) , but the...

Hallo All, I am trying to let two boards communicate over a RS485 link at 3 megabits per second. One board has a LPC2368 and the other has a LPC2136/01. Both the LPC2368 and the LPC2136/01 have a 12 MHz crystal and are using the PLL to run at 48 MHz. The RS485 tranceivers are capable of 12 Mbps. Everything goes fine up to 500 kbps, but at 1 Mbps or higher the transmission has a una...

Just tracked down another issue with "reinvoke ISP" that I just wasted another few hours finding, further to my post below a while ago..... This is on LPC2136/01 but probably applies to many other parts The "Reinvoke ISP" IAP command does not reinitialise the SP (R13) to a place that makes sense for use when ISP is active, so if you enter with SP in an unfortunate place ( like ISP workspace...
