I have done the hardware implementation using the planned schematic below. but somehow no sound seem to be able to play from the speaker except some noises. Anyone can help me check if something is wrong with DAC shematic?
Components used:
DAC - DAC0832LCN
2Mbit EEPROM - M27C2001-12F1
amplifier - MIK3860825/2
8bit Latch - SN74HCT573N
AND Gate - MM74HCT08N
speaker is 8ohm speaker
please advise. At a lost bcos not sure is hardware having problem or software.
Hardware is exactly the same as the schematic.
short description: sound files are burnt into eeprom. uP sends the sound data from the eeprom to the DAC. DAC output is amplified via the LM386 and put through to the speaker
eeprom segment address starts from 4000H, DAC is on PCS2
currently trying to take any data from 4000H onwards to be sent to the DAC
