This program get 3 times sample for each potentiometer, then use average value and for digital input simple reading pin is used, then sends all values as ppm signal to specified ppm output at timer interrupt, each 20 ms.<\/p>\n It also uses one of ADC channel for reading battery voltage and 3 levels are defined for different blinking the battery Alarm Led.<\/p>\n Because different models of potentiometer have a little different behavior, it needs at first to calibrate each potentiometer that give the best range in 1000 to 2000.<\/p>\n In this version the “exp” or “end point” for sticks is not defined and I think that for Arducopter it’s no needed.<\/p>\n I used this program about 2 years with your ULRS versions 1.06 and 2.xx and hadn’t any problem .<\/p><\/blockquote>\n User WinerS did something apparently impossible<\/a>, integrating an APM board inside an OrangeRX case !<\/p>\n Rcgroups user ‘xfly’ is working on an antenna tracker<\/a> that can work with Ultimate LRS : Rcgroups user ‘gregd72002<\/a>‘ describes in this post<\/a> how to connect ULRS with a bluetooth joypad through a Raspberry pi :<\/p>\n Antennas DIY ground plane antenna Here’s the DIY ground plane antenna from\u00a0Chavdar Pechev A DIY ground plane antenna (France) User ‘salience’ from rcgroups made a ground plane antenna with extremely<\/p>\n","protected":false},"author":1,"featured_media":0,"parent":0,"menu_order":60,"comment_status":"open","ping_status":"open","template":"","meta":{"footnotes":""},"class_list":["post-856","page","type-page","status-publish","hentry"],"_links":{"self":[{"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/pages\/856","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/comments?post=856"}],"version-history":[{"count":65,"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/pages\/856\/revisions"}],"predecessor-version":[{"id":3081,"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/pages\/856\/revisions\/3081"}],"wp:attachment":[{"href":"https:\/\/www.itluxembourg.lu\/site\/wp-json\/wp\/v2\/media?parent=856"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Antenna2\"](\"https:\/\/www.itluxembourg.lu\/site\/wp-content\/uploads\/2015\/09\/Antenna2.jpg\")
