Matt Congratualtions on getting the MSP3430 working. I'll add this to the driver. If I record the autodetected chip type I can switch between the existing code and the new code based on the sting the MSP returns. (In theory, one of the EEPROM locations also tells me the MSP type. (Well done to Hauppauge), so I could use that. But I'll use the MSP sting so it works on non-hauppauge cards too (in theory) You mentioned MSP register 0x21. This is for the European NICAM stereo format. > Notice the reverse of the loudspeaker set between the example and current code. Not really. The MSP chip has 2 or is it 3 output channels. One is called the Speaker Out. One is Line Out? or something. The idea is that you have independant volumes on each channel. (Eg, you may have a TV with an MSP chip in and with line out too for your HiFi. Then you turn the TV set speakers down via your remote control, you sill want the line out (for your Hi-Fi) to remain unchanged. > Couple things to mention, I don't know why there is a need to set the > FM/AM Prescale or the FM matrix, but I'm not entirely sure what they do. > Also, the msp_write(bktr, 0x10, 0x0020,0x0020); might be better replaced > by msp_write(bktr, 0x10, 0x0020,0x0001); so the driver auto-detects input > (?) rather than assuming BTSC-Sterio. Auto detect could be handy. But we can try that later (or try it when someone complains Bye Roger -- Roger Hardiman | Telepresence Research Group roger@cs.strath.ac.uk | DMEM, University of Strathclyde tel: 0141 548 2897 | Glasgow, Scotland, G1 1XJ, UK fax: 0141 552 0557 | http://telepresence.dmem.strath.ac.uk To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
