OSCCON = %01111000 '16MHz HF, software PLL disabled ' _CONFIG _CONFIG1, _FOSC_INTOSC & _WDTE_ON & _PWRTE_ON & _MCLRE_OFF & _CONFIG _CONFIG2, _PLLEN_OFF & _BORV_LO & _LVP_OFF ' This code is for using TM1637 with Four-digit 7-segment LED Display I would highly appreciate any helpful hint, suggestion or sample code. The only issue is, the display shows nothing! Since I know that the module is working fine with Arduino, it's my code in PBP that needs to be looked into. After some tweaking, I managed to get everything correct (Screenshot file attached). I used Saleae Logic Analyzer to check whether the Clock & Data pulses and Ack were all OK. When I tested the code, the diagnostic LED blinked, but after that nothing happened. It should make the number '2' appear on the leftmost digit of the display. The code I wrote for PIC 12F1840 is shown below and it is extremely simple. Secondly, while transmitting a byte, the LS bit is sent first. Like I2C, it's a two-wire interface but you can have only one slave on the bus and hence there is no slave address. The protocol followed by the chip is very similar to I2C with a few differences. After spending some time with the library file, I decided to study the datasheet of the chip and write the required code in PBP. The module works fine with Arduino, but all the important instructions to interface with TM1637 are in the library file (TM1637Display.h).

There is a 0.56' version and that costs about $ 1.25. The price of the TM1637 4-digit 7-segment 0.36' display module is about $ 0.60 in Ali Express. For the past 10 days, I have been trying to make the TM1637 work with PBP 2.60C but till now I have not been successful.
