Several months ago, I bought a handfull of TM1638 8-Digit/7-Segment & 16 button keypad modules identified as "HCW-132". They were really cheap and I thought I'd add them to some on-going projects as...

My last forum code example contribution was about a year ago, and provided sample code for the TM1637 7-Segment LED driver/controller. The TM1637 is used on 4-digit 7-Segment display modules...

Following my original post and code example, I hand-wired a 4x4 pushbutton keypad into the TM1637 to experiment with its key scanning capability. The attached photo shows how this turned out.
I...

Microcode Studio accommodates the use of alternate programming hardware devices, such as the PICKit3 & 4 and Microchip development board on-board programmers, so that the single click "Compile...

Employing undocumented commands with a "WS0010 equivalent" controller would cause me many sleepless nights. I've learned to stay well within the boundaries of product specification sheets.

Further to my earlier post, I can confirm brightness can be controlled by turning the display's internal power on and off. Specifically, the command $FE, $13 uses the "Cursor/Display...

I was similarly perplexed by the Chinese-only taobao website. The photo at taobao showed the part number as "YB1602-OLED" and referenced a website yab-lcm.com, which is where there was a non-OLED...

I think I found the display you are using at http://www.yab-lcm.com/en/yb1602/113-415.html. If this your display, it appears not to be an OLED with a Winstar 0010 controller, but a backlit LCD with...

This short demo code provides the basis for using Winstar WS0010 based OLED Displays in the SPI (3-wire) connection mode. If other Forum members are interested, I could pursue rolling this into a...

I've investigated PICBASIC's SHIFTOUT command and have found that it can be used to write to the TM1637, when used with bit-banged start, stop, and acknowledge sequences.

The attached demo...

I can confirm the manual potentiometer brightness adjustment capability as is described in the Winstar OLED App Note Ver. 3.4 (2015/01/27). Page 8 illustrates wiring, but it notes that an option...
