great, it's good to see, that there's some wip. > The first patch adds on ly the new model so that it can be > detected: http://perso.wanadoo.fr/septieme/MD6471/00_add_md5345.patch > I think it is OK to check in, but I'd wish other people working on the > genesys backend to have a look first. One comment, you're introducing DAC_WOLFSON_5345 - why? The settings are the same as for the ST24. Probably they're using the same Wolfson-DAC. I think it's not necessary to define DAC_WOLFSON_5345 - I'll change it back to DAC_WOLFSON_ST24 (in the device settings) and apply the patch to CVS - if this is okay for you. > The second http://perso.wanadoo.fr/septieme/MD6471/01_misc_fixes.patch > contains would be fixes in registers init: > - memset regs so that we are sure that unset registers are zeroed > - disable gamma in R05, since we don't use it yet > - init R06 should be okay. > The third > http://perso.wanadoo.fr/septieme/MD6471/02_add_gpo_struct.patch > adds a Genesy_Gpo struct to manage GPO differences between models, in the same > way that Genesys_Sensor does for sensor.

Hmmmm, the problem is, that at least you need to figure out the various parameters for your motor. I don't think, that the MOTOR_GEAR is the only one to tweak. I think it's necessary to figure out how to get the necessary parameters out of the USB-logs. Futhermore I think the function we currently have needs some cleanup - think of the overwritten parameters... I'm planning to do some more work on that during the next days. > - and last, what is the start point for y_offset_calib and > x_offset_mark ?
