PHCC Daughterboards

explain Daughterboards here.

Input

Pushbuttons, Switches, Rotary Switches, and similar.

Keymatrix Daughterboards

• KEY64D_PH

Stepper Controller Daughterboards

• DOA_stepper_293

Aircore Controller Daughterboards

• DOA_stepper_293 (with different firmware)

LED, 7-segment displays, and other segmented displays

Segmented displays (7-segment, 14-segment, starburst, etc), LED bargraphs, as well as individual LEDs can be driven by the following controllers:

• DOA_7seg (both common anode and common cathode)
• DOA_877_4067 (old, runs only on slower DOA clocks)

LCD

see UPHCC sister project.

D'Arsonval Meter Movement

D'Arsonval meter movements, aka. galvanometers, can be controlled directly from the DOA_AnOut1 outputs.

• DOA_AnOut1

Other

USB interface

• PHCC_usb

Quadrature Rotary Decoder

• PHCC_rotdec

Bus Terminator

• DOB_term (terminator for the end of the DOB bus)

Bus Repeater/Amplifier

see Bus Differential Converter.

Bus Differential Converter

• PHCC_LXLAT_DOA-dDOA (level translator DOA->differential DOA)
• PHCC_LXLAT_dDOA-DOA (level translator differential DOA -> DOA)

Testers

• PHCC_ParportTester_DOA_DOB

Non-PHCC

• THVP, a parallel port PIC microcontroller programmer (aka. PIC burner)
