Arduino Controller: NES Turbo Fire Buttons!

Sat, 15 Jun 2024 22:19:32 GMT

NES Controller interceptor/emulator with turbo fire feature added
PCBWay Supports High Precision Advanced PCBs: https://www.pcbway.com/
NES Connector Breakout Design files https://github.com/GadgetReboot/NES_Controller_Breakout
Turbo Fire Sketch https://github.com/GadgetReboot/NES_Controller_Interceptor
NES controller circuit with 4021 https://www.allaboutcircuits.com/projects/nes-controller-interface-with-an-arduino-uno/

There is no project schematic since it was just stitched together.
The 4021 controller circuit from the allaboutcircuits.com link was assembled on a breadboard. The latch/data/clock as well as +5V as GND from that circuit were wired to a spare NES plug/cable to plug into the NES.
The 8 button inputs to the 4021 were wired to 8 digital outputs on the Arduino Nano (see the sketch for the pins used).
Then the Nano has a latch/clock/data set of pins that are used to connect to a NES controller using the 7 pin connector breakout board. That breakout board also has +5v/GND from the Nano to power the NES controller.
The GND from the Nano and from the 4021 circuits must be common.
The Nano's 5v power can come from the NES +5v supply on the 4021 circuit or if that gives problems, the Nano can have its own separate USB or other 5V power source.

DTMF Decoder and Phone Audio Matrix Switching

Tue, 19 Mar 2024 12:37:08 GMT

Playing with a revised DTMF decoder MT88L70 3.3v power/GPIO, and audio matrix switching.
PCBWay Supports High Precision Advanced PCBs: https://www.pcbway.com/
PCBs at PCBWay https://www.pcbway.com/project/shareproject/DTMF_Decoder_3_3v_MT88L70_e9c3218d.html
Design files https://github.com/GadgetReboot/DTMF_Decoder_3V3

Using a 3.3v powered DTMF decoder makes it easier to interface directly with ESP32 compared to the 5V version, which requires level shifting.
The ongoing phone line experiments may expand between just two node direct interfacing.
An MT8808 8x8 analog crosspoint switch is being tested to see if phone line audio can be routed between channels. This may enable a central coordinator to manage call requests and phone line routing between multiple nodes, including multi node party line call connections.
