Re: Tang Nano 9K - a (n almost) perfect 65(x)xx platform

Hi,
Tried out the 65c02 experiment core but nothing was seen on the Teraterm terminal. Any key presses will lit the led.
I also added the full path to the rom.init file and processed the project under Gowin Ide. The Gowin nano 9k uart examples all verified to be working.

Re: WDC Tools Free download!

Yes I did download the "free" tools in Jan 2015.
Only the assemblers and debugger worked. (WinXP and Win7).
TIDE seems to give error upon closing and weird project management.
Anyone downloaded their free tools and the C compilers (command line) able to compile stuff without license key?

Re: WDC Tools Free download!

Hi,

The WDC Tools suite is not free after all.
I should have bought it when it was US$40. :cry:
I have bought 5 pieces of WDC65C816 for evaluation with FPGAs.
Does that count as using their technology?

Re: WDC Tools Free download!

Not winning any fans over to the W65816 with their tools if it continue to be like that.
Seems like WDC is comfortable where they are now.
People usually learn some high level language first then go down to assembler. Thus
tools should have a C/pascal/basic compiler eg Programmer's notepad and ...

Re: WDC Tools Free download!

wdc816cc.exe and wdc02cc.ex license error even on command line (Win7 home 64 bit).
Can I still purchase the license though its free?

Re: WDC Tools Free download!

Downloaded WDC Tools on 28-12-2014

Looks like only the assembler and linker tools are activated.
The C compiler still requires a valid license.
Or that I'm missing something?

thanks.

FPGA in PLCC68

Perhaps members here have seen and used one ?
Seems convenient and useful like PSOC.

Re: SD Card interfacing

Hi,
I was using a SD card with FatFs on a Apple 2 with a VIA 6522 card.
The VIA shift register is used for sending a byte to the SD card, whereas a bit-bang routine (from some C64 group on the Net) was used for receive.
A low ohm resistor is placed between CB1 (SR clock for Send) and Port B0 (Bit ...

Hi,
I've visited this board many times and have just realized that I'm registered a year ago. I've enjoyed reading all messages, past and present, in the forums. I'm waiting to purchase a user-designed modern W65816 SBC preferably using W65xx peripherals, sd card with video graphics and decent ...
