Finally after several days, I’ve managed to get the start of display initialisation code in for my #PC6502 stack and I can write and read data to/from the display using SPI (65SPI2).
Console output -
RUN
RA8875 INIT:
CMDWrite>: 0x80 CMD>:0x00
DATAREAD>: 0x40 Data<:0x75Ready
So the next step is to add in rest of the init code and try to write hellos world on it.

Morgen ist es soweit.
Um 20 Uhr werde ich den Stream starten, ob wir dann fertig sind oder nicht. Geplant ist aktuell um 20:15 (Ja, die Filmfilm Primetime) zu beginnen.
Da wir sicherlich wieder das Audiorouting gerade ziehen müssen. Den Stream noch mal umstellen werden und den Chat mitlesen, wird das bestimmt ein coller Abend.Seit dabei unter https://owncast.onpremis.es
Nur echt mit dem bitsprung
Dafür steht @[email protected] mit meinem Namen =P -
Call me weird, but I actually like getting a bluescreen on kernel panics now:
tux ~ # grep '^CONFIG_DRM_PANIC' /boot/config
CONFIG_DRM_PANIC=y
CONFIG_DRM_PANIC_FOREGROUND_COLOR=0xffffff
CONFIG_DRM_PANIC_BACKGROUND_COLOR=0x0000ff
CONFIG_DRM_PANIC_SCREEN="kmsg"Maybe I should change the background color to 0x0000aa and use a different console font for a more authentic experience, though? 🤔

Als letzte Option noch die Verbindung eines #Calliopemini 3 über #WebUSB probiert. Formale Kopplung ok:
const device = await navigator.usb.requestDevice({ filters: [{ vendorId: 0x0D28, productId: 0x0204 }] });
Beim folgenden await device.open(); kommt jedoch direkt access denied. Alle nachlesbaren Ideen halfen nicht, u. a. mit einem Tool namens »Zadig« WinUSB-Treiber nachzuladen. Fehler bleiben gleich, aber man zerschießt sich damit auch die bisherigen funktionierenden seriellen Zugriffe.

So I looked at the #datasheet (https://files.waveshare.com/upload/2/29/7.5inch_e-paper-b-Specification.pdf) to find what I had to do to display some red colour. It seems I have to send 0x04 for each red #pixel, 0x03 for black and 0x00 for white.
Checked the existing #driver and, sure enough, it sends 0x03 and 0x00! This seems to be the right way.

How I found the Game Genie codes using FCEUX:
1) By looking at the CHR ROM, I knew I wanted to use tile 0xd2 instead of 0x0a and 0xd7 instead of 0x0e.
2) I looked at RAM in Hex Editor. A copy of sprite data was at 0x0700-0x07ff. The cursor was in the 2nd sprite slot, so the tile was at 0x0705.
3) I set a breakpoint on 0x0705 write in Debugger. It found STA $0701,X. The previous instruction was LDA ($00),Y. Whenever that was run, RAM 0x00 contained 0x98 or 0x9d, RAM 0x01 contained 0xd8 and Y was 1, so a byte was being copied to A from RAM 0xd899 or 0xd89e.
4) Indeed, during gameplay, CPU address 0xd899 contained 0x0a and 0xd89e contained 0x0e.
5) I used https://www.nesdev.org/nesgg.txt to create the codes:
- XSOSOEZA = "if the CPU tries to read a PRG ROM address that's currently mapped to CPU 0xd899 and contains 0x0a, return 0xd2 instead".
- NSOSVETA = same but 0xd89e, 0x0e and 0xd7, respectively.
