Re: joymon - R/W/X-capable monitor over the controller port

Congratulations socram on the project.
Regarding the serial usb converter, is a specific model of FTDI chip required, with line inversion, or similar, or does any of them work?

Re: PAD Serial

Did you consider "signal reflection"? The old BNC ethernet cables did use BNC terminators at the end of the cable to avoid Thank you very much for your help. I have not taken into account the reflection, I thought that working with 250 Khz, it would not influence much. When I started the ...

Re: PAD Serial

Or is there some hardware issue that prevents higher speeds? I am sure that could be fixed by adding some resistors or diodes in the console or in the cables. Thank you. The maximum stable speed I have reached is 71680 bps, 8 KB/s. I don't remember all the exact tests, but with pullup resistors, pu...

Re: PAD Serial

Sorry for the delay in writing, but there is little time to spare. So far the main problem we had in testing was the speed of the serial port, in particular the input, especially on an arduino nano atmega328. This problem is easily solved by doing without it, i.e. storing the PSXEXE in the arduino's...

Re: PAD Serial

I am creating a charger for speeds 12 to 25, selectable from a PAD controller connected to port 1 or 2. I also allow to choose the ARDUINO connected to port 1 and 2. Since you cannot have both the control and the ARDUINO at the same time, by sharing SPI, when selecting the speed, you can detect the ...

Re: PAD Serial

Bye bye RealTerm and Windows.
I have finished the SEND utility, which is similar in operation to the REALTERM, but working in DOSBOX.
It is required to edit the DOSBOX configuration file.

Code: Select all

serial1=directserial realport:com21

Code: Select all

SEND frame.txt 1050 115200

Re: PAD Serial

I throw a question to the forum, if you can help me. In the psxsdk to send a custom message, it works perfectly: void SendData(int pad_n, unsigned char *in, unsigned char *out, int len) { int x; int y; int i; PADSIO_MODE(0) = 0x0D; PADSIO_BAUD(0) = 0x88; if(pad_n == 1) PADSIO_CTRL(0) = 0x3003; else ...

These days I've been having fun like a kid with new toys. I've removed the check against the memory executable, so I can load whatever I want for testing (I haven't uploaded it to the repository). I've been testing all the homebrew and demos from the demoscene with the cable at 1856 bauds. Since it ...

Re: PAD Serial

And another new record. I got 1856 baud at 58 fps with speed mode 11. I have given it a twist, and I have managed to pack in the 4 byte analog mode. It's quite confusing to explain, but basically, as the bit 7 of the sticks gives problems, I've left it unused, allowing to use the 3 bits of the high ...

Re: PAD Serial

I set a new record with the ARDUINO (fake spi mode), namely 928 bauds at 58 fps NTSC. I used the analog mode sending 16 bits. In each stick, instead of sending one byte, I send 1 nibble, since there is overlap in the communications. As I have commented, all these solutions, prevent us to achieve the...
