STM8 DISCOVERY – 7segment serial link (2)

PIC 16f884 LED display posted by (C)takao21203 Using a PIC 16f884 here to test some new ideas. All the I/O bits are now freely mapable from tables. The TRISTATE is computated by the firmware.Actually these small displays are not very bright- or maybe there is a mysterious bug.

STM8 DISCOVERY – 7segment serial link (1)

stm8 board posted by (C)takao21203 This is a STM8 Discovery board. I have added a PIC 16f884 and a small 7segment display. I want to program a serial link between the two controllers. Later, a display will be connected to the STM8 chip directly. However, I have some ideas to improve the 7segment decoding/driving, and it is easier to test … Continue reading

serial LED 7-segment display

I have been working on these for a while now, including to build various prototypes. At one time I used buffer registers to drive the multiplexed LED display, and this works, but it is still quite an effort to wire. I made PCBs based on this technology. The buffer chips still take up considerable PCB space. Then I tested a … Continue reading
