Hi! Following on my project to include support for the OpticFilm 7200 (by Plustek) to the genesys backend, I have some questions to the maintainer(s) of the latter:
1) Are the AFEs taken into account for the moment all made by Wolfson ? The Genesys_Frontend stuctures are different for the UMAX, ST12, HP2400c, etc. I wonder why. 2) Concerning this same structure, I don't understand exactly the meaning of the four values put in reg and the three put in reg2. Apparently being register contents corresponding to extra registers (we already have the three gain registers and the three offset registers), it would allow for seven configuration registers for the AFE, which looks far too much for me. In my case the AFE is the AD9826, and it has only two 8-bit configuration registers. 3) At the same point, in "sign", correct me if this is not the sign bit (bit#8, i.e. the ninth of the field) of the offset for each of the three channels. 4) There seem to be some mistakes (or things I don't understand :-)) in the addresses given to the sanei_genesys_fe_write_data function, in genesys.c and genesys_gl841.c. For instance, for the red gain, I can see the address 0x28, which doesn't seem to match the Wolfson WM8192 chip documentation (please indicate which is the exact AFE used, but I think the register addresses are pretty much the same for all WM chips). 5) As I could have other questions in the near future, please allow me to write directly to you (dear maintainer(s)) in the future, cause it could become boring for the other readers of the list. Problem is I don't know who is in the current maintainer's team concerning the genesys backend (Pierre ? St?phane ? Gerhard ? Henning ? Maybe I will do some kind of temporary restricted ml...) See you, and thanks for your help. JB
