matlab recieve wrong data at 19200 bit rate ,not all data,some samples are incorrect,i want to know solution microcontroller type: atmel 8951 plz i need fast reply because my project may be failed
yes, he is right and gives the answer.
hi i need some code with opto isolator to isolate a square signal which is between 5 and -5 with freq of 250khz . if you can give me an opto isolator which works in 250khz or any code using optp isolator , i would be so thanks full .
printf is too slow for 250 KHz since it has rise time max 10 microseconds and fall time up to 122 microseconds. T that gives you just 50 khz???. i could use h11x. switching time for this family is 32 microseconds which gives you range up to 333 khz.

Are you for real? What has an opto-isolator in common with Matlab? And what has this to do with Keil?
