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 circuit posted by (C)takao21203 Added some shuttle boards to the STM8 … Continue reading

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

working at 32×24 LED matrix, PIC 16f59


This gallery contains 8 photos.

Working at my LED matrix. 768 LEDs! 32×24 pixels. I want to write a 3D graphics demo. There are electrical issues. The display drive did not work correctly and during 3 days I was not able to figure out what’s wrong. So I removed all of the ICs + replaced with more advanced technology. I use a 16f59 microcontroller now … Continue reading
