Hi all,
I am working on LPC 2148 with SD card interface, for my application i need to log the data in SD card for every 20ms, Hence i open my log file for each updates,it takes less time but for closing the file it takes more than 60ms, so there is a chance of missing logs on my file. Is there...
Hi all,
I am successfully integrating SD card with LPC2148. Am able to read write data in .txt, .csv files. While opening and closing of file it takes too much time, fopen() takes 8ms, and fclose() takes around 68ms. Its too over for my application for writing the content it just takes the...
Hi HTA & andre_teprom,
Thanks for your response, i got the output for a specified pattern, now i am going to interface with my modules & also work for push button on rotary encoder.
Hi andre_teprom,
I got the pattern when i rotate it very slow manner,if I rotate some speed it neglects the transition states 01,10 thats my problem.
I am also added some delay using timer.
Hi all,
I am working with Rotary Encoder model number ALPS EC11E09244BS, interfacing with LPC2148,I got a pattern in LCD as 00,11 between these state a small transition occurs while changing state from 00 to 11 its changes from 01 and 11 to 10. But these are get in slow transition only.
my...
Hi udayan,
Thanks for the response actually in the code hardware selection in RTA_Config file hasn't been set properly but now the issue is solved and now i can easily write into the file and also read from that.

Hi all,
I am working on SD card with LPC2148 in RTX-Flash system, i am using NEX-robotics board it communicate via SPI0 but the RTX uses SSP in demo codes. I have changed the demo coding to SPI0 for the configuration, I have attached my changed file and original demo code with this. Can anyone...
