Ardu interface via radio dual baud rates...

-

hi all,

i wonder if ardu guys can help...

we involved in project have parameters can change , cant....

ok....to paint picture...

we have vb/vs app have written, control camera , servos.

in between cam , pc/lap have 57k radio link

the baud rate cannot change.

so....the problem is....we need send 'commands' / 'words' ardu (not difficult) ardu has respond sending rs232c visca @ 9600b fcb cam.

e.g send word 'zpos1' ardu @ 57k (radio link) ardu responds sending hex command out fcb zoom in or zoom position @ 9600.

in reverse, send word 'zpos10' again ardu responds sending relavent command. (zoom wide in case) 'words not important, have serial out working vs, dont know if can output rs232 @ dif rate input?

some sample code or example great here, have hit wall largly......

thanks in advance suggestions....

regards,

mike.

basically hardware in arduino fixes tx , tr rate same clock can't split speeds. use software serial library have serial port operating @ diffrent speed hardware.

remember need voltage converter change ttl logic levels arduino rs232, max202 or similar.

hello ! wrote today article on blog cpu load monitoring (using gpio , leds) on raspberry's. simple (written in little shell script), think can useful (for people want learn leds stuff on r. pi) there 5 leds turning on , off regarding cpu load: - cpu < 20%: 1 led - cpu < 40%: 2 leds - cpu < 60%: 3 leds - cpu < 80%: 4 leds - cpu < 90%: 5/5 leds - cpu >= 90%: 5 leds flashing here article: written in french, can watch youtube video , download code @ bottom of article. http://www.chteuchteu.com/2012/10/26/ra ... e-au-gpio/ if find errors in code, can post comment on article. ! up code enhancements ? raspberrypi
