Hi, did you think about what I proposed you ? Implement the 8 bit Sound Blaster 16 commands : Set Frequency, 8 bit High Speed DMA signed. It is "Only" adding existing commands that "No" software will use as the board is seen as a SB 2.0. This will allow to setup the frequency more precisely and …

In-system flashing will be available with next firmware release (3.0). Out of curiosity, did you take the bootloader approach when implementing self-programming of the MCU, or was there a solution you liked better? Yes, it happened that with a bootloader mcu can be reflashed without introducing any …

Has anyone tried the Blasterboard on windows 3.1 (standard mode) using the Soundblaster 2.0 drivers. When I tried it, the drivers crashed out with a general protection fault. I am just wondering if other people have seen this fault occur. This works perfectly fine with a real SB 2.0. I need to …

Bad ones will put out a lot of noise, which I try to eliminate with linear regulators in the first place. As long as measurement of real hardware will stay within ISA current specs - I will not consider adding DC-DC converters. For sure. Linear regulators are the way to go in analog and mixed audio …
