Hello, I wish to migrate my legacy designs from 8051 to LPC 1768. I am not clear from the datasheet of LPC1768 what total current can I sink on port pins individually and collectively. Currently I can drive optocouplers like PC817 etc directly with 8051 port sinking more than 5 ma each pin. Shall I need to interface through some buffers like 74ACT245 or such to meet that requirement of current? R...

I have a project that requires two 12-bit ADCs with parallel output and a sample rate of ~20-30 Msps. The micro will be processing the data into a bit stream, formatting that into a data packet and sending it out via a canned wifi solution. I could use an FPGA instead of a micro but it would add a lot of cost and time to the project. I could just try it with an LPC1769, 120MHz, FIQ, for exa...

Hi everybody, I try to use the Uart0 on my lpc1768, but after a lot of hours I can't obtain the correct baudrate. So communication is wrong. Some one have a simple example to explain me how I can do correctly? Here is extract of my codes and comments 1) First of all, in the main, I call the SystemInit function (writed by nxp team - file system_LPC17xx.c vs 1.03) where clock and perip...

I am using this Olimex LPC-2106 Dev. board. I can download and run the program demo2106_blink_ram from the ram. But when I try program the flash with the test program demo2106_blink_flash after checking for blank flash, it would show the blue progress line but would not blink the LED. I followed the steps below: 1.I powered up the board connected the rs232 cable to computer and the board, the sa...

Hi everybody, I need some help. How can I crosscompile the libmodbus (libmodbus.org) for the lpc1768 ? Usually my code is wrote into CoIDE (from coocox) and compile with arm-none-eabi-gcc (with modification from Coocox). But I don't know how to do to have a static library usable. Any people can explain to me ?

Hi all. have question form different side. Is possible make easy end low cost MP3 player (mono, FM quality) with any LPC MCU??? is it possible. LPC2148 is possible to use (need 33kB ram and 110kB flash) but this MCU in min qty 1000> is not cheap. other MUC. now I test audio player with VLSI chip VS1000 (only ogg file play) work. but need external spi flash , and need external ADC (need this in

I have a problem with a LPC2468 board. I use Yargato on Eclipse and configured everything as in the description. I changed an example for LPC series to fit the LPC2468. (Amount of flash, ram and adresses) Compiling is without any errors. When I start the GDB, the segger console says: Reading all registers Read 4 bytes @ address 0x00000000 (Data = 0xE59FF018) Target endianess set to "little e...

There was a question in Keil forum about the max SPI speed that could be achieved using SSP in LPC1788 and a core clock of 120Mhz and based on the user manual the max speed for the SSP peripheral is core_clock/2 which gives 60MHz. Assuming that the PCB is designed to work fine with this speed, is this achievable from the MCU side? Is it possible for the output stage of the LPC to switc...

Hello i trying to make pc oscilloscope using lpc 2148.. 1)what would be the maximum 'digital signal' frequency i can apply at the inputs of lpc 2148 for proper processing? 2)As said in datasheet, for 10 bit ADC max sampling rate is 400 kSPS so what sampling rate should i take for proper regeneration of input 'analog signals' on display? or if i set the sampling rate at

Hey guys, I'm in a bit of a bind. I am using an LPC1764 with LPCexpresso version 5.2.6 with an LPC-Link 2. The problem is that I'm not sure if my connections are right or if my software is configured correctly. Here is a simple layout of the connections: http://i188.photobucket.com/albums/z265/fac7orx/eepromARMpic_zpsdc524e83.png Here is a link to the EEPROM datasheet: http://ww
