7 days ago – So now I am porting the MCP23017 based LCD1602 test functions toGuzunty Pi. The highest level test function is listed below.
Mar 11, 2013 – gz_8p8i waveformIn this core, the inputs work like they do in ordinary IO cores, but the 'pwms' output bus switches each bit dynamically ...
Mar 11, 2013 – But I am worrying that my Guzunty Pi will refuse to load again, as it did the very first time. I guess there should be some intermittently failing ...
Mar 11, 2013 – Now I can see the RPi Guzunty Pi connection. I am making a summary below.1. JTAG - 4 pins2. SPI - 5 pins3. I2C - 2 pins4. GCK 1, 2 - 2 pins5.
Mar 11, 2013 – Now I am studying the Guzunty Pi's demo PWM program.The Make file contains the following statements.SRC = gz_4p8o8i.
Mar 11, 2013 – I found the Guzunty Pi schematic has two pins both labelled GCK2. I guess it is a typo mistake. Need to check out later..END.
Mar 11, 2013 – So I looked into the Guzunty/Pi/ directory and checked out the gz.test program. I first found the Makefile which I know is sort of MSDOS3.3 batch ...

Mar 11, 2013 – Now I have connected the RPi P1-07 signal GPCLK0 to the GuzuntyPi's corresponding 26 pin plug pin 07.Then the scope displayed what I ...
Mar 12, 2013 – Now I am reading Guzunty Pi's 16o8i example program, trying to see how it writes. The following is the relevant sections. int gz_spi_write(byte* ...
Mar 11, 2013 – Now I have extended the RPi's PWM and GCLK signals to a proto board on the left of the Guzunty Pi. I then execute the gz_test program to ...
Mar 9, 2013 – I checked the wiring and found that I forgot to connected GuzuntyPi's 3V3 pin to RPi's 3V3 pin. So there was no power to CPLD. I added the 3V3 ...
Mar 11, 2013 – Now I have extended the RPi's PWM and GCLK signals to a proto board on the left of the Guzunty Pi. I then execute the gz_test program to ...
Mar 13, 2013 – Now I have tidied up the wiring again, before playing with RPIO.PWM..END.
