I hope everyone is having a happy holiday season. If this isn't your holiday season, then I hope your having a happy normal season. Anyway...
I got a HAL component compiled and nearly working for my serial DAC project, but I have some issues that would like to get help on. Some information is here: http://www.wallacecompany.com/machine_shop/EMC2/serial_dac/ I am using EMC2 2.2.2. I get "unrecognized type" errors when I try to use u32 in my standard_pinout_dac.ini. I changed all u32's to s32's which stopped the type errors. Since I am only using the lower twelve bits, I guess, it shouldn't make a difference. Between the motion.spindle-speed-out float, and my 12 bit serial stream, I am losing four MSB's. I run spindle-speed-out through scale to get 12 TRUE bits at full RPM. Then, because my DAC component data input is u32 (or currently s32), I convert the scaled float with conv_float_s32.comp. Since halmeter indicates that I have a value of 4096 at my DAC component data input, all the bits seem to be getting to my input. I "and" (&) 0x800 with the s32 input to pull the MSB, and then shift 0x800 right for subsequent bits. Actually, I am currently using 0x1000 instead, to fix another problem, but this should not affect more than one bit and I have four unruly bits. Thanks for any help. -- Kirk Wallace (California, USA http://www.wallacecompany.com/machine_shop/ Hardinge HNC lathe, Bridgeport mill conversion, doing XY now, Zubal lathe conversion pending) ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
