See the attachment. It has a TM1623 LED controller. It showed me meaningless characters. See tm1628 the commands datas refer to the datasheet of TM1628. It called TM1628. For Display the main command is datasheet 0xC0 followed by 14 bytes of data ( incase of incrementing the addresses), otherwise it would tm1628 be command 3. How can I port the TM1628` s library to TM1623? Eleven segment output lines control circuit, 1 segment/ grid output lines, six grid output lines, one display memory key scan circuit are all incorporated into a single chip to build a highly reliable peripheral device for a tm1628 single chip microcomputer.
hi i' m using arduino uno to drive an digtal pot which in turn drives external PWM to take controll of it over the internet using Esp8266. the PWM is used to drive my heater. my heater unit consists an LED display with TM1628 driver IC to indicate the current tempearture and controll temperature of heater.
