Wiki-spamming is not tolerated, will be removed, so it does NOT even show up in history. Spammers go away now. Visit Preferences to set your user name Summary of change: I have a new unassembled GenBoard that I havent got working at all yet. Done so far: ---- '''Serial connection''' Soldered EC36 and EC18, EC18-pins14&15 to MAX232 and EC18-pins14&15 to serial cable '''Exact pin-pin end-end connections ?''' (obviously very important. Measure) * DSUB9/2 ... * DSUB9/3 ... * DSUB9/5 ... ---- All (you mean FETs and IGBT-s ? or stepper too ?) necessary output drivers and lastly the inductor 1R5 (from the rescue kit). Connected the board to a JimStim 1.3 (http://www.jbperf.com/JimStim/index.html) EC36-Pins5,21,22,26,32 to JimStim accordingly, EC36-Pin25 also to JimStim, serial GND to common ground point between GenBoard and JimStim. At this point I tried to get first connection with GenBoard. Tried several methods to connect but didn't get any answer. * '''Exactly ?'''' ** baudrate, command ? At least try these: * 19200,8n1 'S' command * 9600,8n1 'Man' command * 9600,8n1 'S' command Loopback tested my serial port successfully. To be sure that board is powered I measured the MAX232 and the processors Vcc voltage which was high as 10volts. '''10 Volts ??''' compared to what ? It should be 5 Volt compared to ground. It is measured, and tested (bootloader is uploaded via ISP, than several tests made via serial). Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
