LedHex #\n\nThis repository contains several programs to run on an Arduino\nand drive a display made from LEDs.\n\nThe display was made as a small-volume low-cost PCB using a design drawn in KiCad.\n\n![LedHexDisplay](ledhexdisp1.jpg \"Completed PCB populated with red LEDs\")\n\n## KiCadV3Pcb ##\n\nCAD files for the schematic and PCB,\ndesigned in 2014 using KiCad V3.\nThis version of KiCad is so old now that it's not practical to update the files.\nAt the time of writing,\nKiCad is at V8.0.5 and uses a completely different set of PCB footprints from V3.\nSo although it's possible to update the schematic files to use the latest format\nand the latest symbols,\nit's difficult to map those symbols to the new footprints.\nThis means that the PCB layout cannot be resynchronised with the schematic.\nProbably the easiest way to fix this would be to re-draw in KiCad V8.\n\nThe schematic is shown as a PDF for reference when writing software\nto drive the display.\n\n## LedHexClock ##\n\nVery simple four-digit clock with flashing colon.\nSo simple, in fact,\nthat there's no way to set the time.\n\nTODO: add a way to set the time.\n\nTODO: add 12/24 hour switch.\n\nTODO: add other types of time display, TBD.\n\n## LedHexCount4 ##\n\nDisplay a four-digit counter on four LedHex PCBs connected in a chain.\nRange is 0000-FFFF (0-65535).\n\n## LedHexLampTest4 ##\n\nTest a four-digit chain of LedHex PCBs by lighting up all the segments\nin sequence.\nThis is also a test of the LED power supply!\n\n## LedHexTest ##\n\nSimply count 0-9, A-F repeatedly on a single digit display.\n\n## LedHexTest4 ##\n\nTest a four-digit chain of LedHex PCBs by lighting up all the segments\nin sequence.\n\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fanachrocomputer%2Fledhex","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fanachrocomputer%2Fledhex","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fanachrocomputer%2Fledhex/lists"}
