How to do serial communication via rs232 android? -


i have android device 'micronet a317' has rs232 44 pins serial port. have device i.e card reader has 9 pin d-pad connector. have connected both device(android & card reader) each other using converter. task make serial communication between these 2 device. please suggest me it.

you can use usb-serial-for-android library transfer data via serial port on android. i've tested library usb-to-serial adapter + usb-host cable plugged nexus 7 usb port.

your rs232 port should represented usb device internally, otherwise library won't work.

you need know serial adapter type (ftdi/prolific/cdcacm) , add usb device vid/pid appropriate driver file function getsupporteddevices().

you can find out serial adapter type , vid/pid running cat /proc/kmsg root shell on device, or inspecting directory /sys/class/tty

datatable - Matlab struct computations -

i download data yahoo! finance with: data = getyahoodailydata({'msft', 'axp'},'01/01/2000', '01/01/2015', 'dd/mm/yyyy'); and data stored 1x1 struct. want create tx2 matrix of daily adjusted closing prices msft , axp, column 7 in each table in struct. how can that? or better : there way make computations directly on information/prices in struct? you can access data in struct name. vecmsftadj = data.msft.adjclose; vecaxpadj = data.axp.adjclose; % if want n x 2 matrix madjclose = [vecmsftadj, vecaxpadj]; % personnaly prefer working table tadjclose = table; tadjclose.msftadj = vecmsftadj; tadjclose.axpadj = vecaxpadj;
