Firmware projects based on libopencm3

Harald Welte 2a91fc857b attenuator.c: DAT-31A-S+ has 6th unused bit ... So In reality DAT-31A-S+ seems to have steps of 0.5dB, but the LSB is "defined" to be alwasy 0. This means we have to multiply the dB value by 2 (shift one left) to make sure the LSB in 0.5dB steps remains 0, and to make sure we actually step n steps of 1dB		2021-04-13 17:19:08 +02:00
