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 ... Measured to SV2/2 '''OK!''' * DSUB9/3 ... Measured to SV2/1 '''OK!''' * DSUB9/5 ... Measured to GND '''OK!''' * SV2/3 ... Measured to GND '''OK!''' ---- Soldered eight FETs, six IGBT-s and lastly the inductor 1R5 (from the rescue kit). ---- Connected the board to a JimStim 1.3 (http://www.jbperf.com/JimStim/index.html) GNDs: EC36/26 -> DB37/19, EC36/5 -> DB37/8, EC36/21 -> DB37/9, EC36/22 -> DB37/10, EC36/32 -> DB37/11, Power: EC36/25 -> DB37/28 , ---- 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 '''Shorted SV2/1&2, tried and nothing happened''' * 9600,8n1 'Man' command '''No responce''' * 9600,8n1 'S' command '''No responce''' 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. I made the assumption that when measuring voltage it's done compared to ground. Actually I tried several. GND on the chips and GND pins on the EC36. ---- It is measured, and tested (bootloader is uploaded via ISP, than several tests made via serial). Bit curious about this. If the board doesn't have any connectors how is this done. How do you connect and power the board?
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.
