No documentation found
mcp3424_set_channel(byte in address, byte in channel) return bit
channel should be 1 .. 4, as per datasheet DS22088B page 18 if channel = 0, 1 is assumed. If channel is > 4, 4 is assumed
mcp3424_get_18_status(byte in address, byte out status) return sdword
get 18-bit adc reading, return status/config_reg read-back to caller
mcp3424_get_16(byte in address) return sword
get 16-bit adc reading, no status returned to caller. legacy routine.
mcp3424_get_18(byte in address) return sdword
get 18-bit adc reading, no status returned to caller. legacy routine.
mcp3424_set_gain(byte in address, byte in gain) return bit
gain should be 1, 2, 4, 8, as per datasheet DS22088B page 18 gain = 0,1 -> 1 / 2 -> 2, 3,4 -> 4 / 5..255 -> 8
mcp3424_get_16_status(byte in address, byte out status) return sword
get 16-bit adc reading, return status/config_reg read-back to caller
mcp3424_set18bits(byte in address) return bit
initialize mcp3424 for 18-bit samples and continuous conversion mode. NB: also sets G=1, channel=0. These may be modified by other functions (see below)
mcp3424_millivolt(sdword in tcvalue, byte in gain) return sword
gain should be 1, 2, 4, 8, as per datasheet DS22088B page 18 if gain = 0,1 -> 1 / 2 -> 2, 3,4 -> 4 / 5..255 -> 8 FIXME: this routine only handles 18-bit samples.
mcp3424_microvolt(sdword in tcvalue, byte in gain) return sdword
gain should be 1, 2, 4, 8, as per datasheet DS22088B page 18 if gain = 0,1 -> 1 / 2 -> 2, 3,4 -> 4 / 5..255 -> 8 FIXME: this routine only handles 18-bit samples.
