DPI Project and Task List
CARDS
New FPGA card
2 rows of 40 pins to give 10 peripheral slots
optional 1 row of 16 pins for host interface card
USB Serial interface with CP2102
easy to cut serial traces and header for raw serial
optional host RTS line for board reset
smaller 98x48mm form factor
SPI configuration flash.
SPI flash is seen as a peripheral for new code download
5 Volt input, onboard 3.3 and 1.2 volt regulators
-
new Verilog serial host interface (first using existing FPGA card)
Dual voltage/current controlled motor controller
-
XL4015. PWM for voltage control. Cycle stealing for current control.
-
Use AVR to set H-bridge direction and monitor voltage/current
Low cost NFETs for H-bridge can have high gate capacitance
Design to work with 7474 DPI circuit or direct SPI
No new Verilog
This might be a big seller
9-axis IMU card
Qwiic interface card
Grove interface card
Programmable power supply
XL4015 based design as above
AVR and quad digital pot to control.
ZXCT1107 for high side current monitor
No new Verilog
RFID reader card
Waveform generator card
Analog CPLD card
Weather sensor card
Temperature, Humidity, Pressure, Light, UV Light
No new Verilog if I2C sensors
