Floating-Point Demo in C on a Sharp PC 1403
มุมมอง 1583 หลายเดือนก่อน
Using the LittleCCompiler, after the upgrade to introduce floating-point variables (though still experimental). C code can also interact with BASIC fixed variables A-Z, as shown. Source code here: github.com/ffxx68/sharp-pc-software/tree/main/LittleC_Compiler.
PC-1403 demo of a print on LCD using the ROM routine
มุมมอง 1625 หลายเดือนก่อน
This video isn't that exciting in itself, but it's here just to show that - after some struggling and long debugging sessions - I finally managed to find the ROM routine to print strings on the PC-1403 LCD. I used the MAME debugger to catch the entry point, then replicated the surrounding ASM code, in a C program for the "Little C Compiler" (github.com/ffxx68/sharp-pc-software/blob/main/LittleC...

CE-140F emulator - first demo on PCB

Showing and testing the PCB version of the emulator
CE-140F emulator demo with LOAD and SAVE
มุมมอง 280ปีที่แล้ว
Here's the first demo on my Sharp CE140-F Disk Drive emulator with the complete SAVE and LOAD cycle, both in ASCII and binary mode, which now allows to work on BASIC files on a regular (Windows, Linux...) PC and share them with the Sharp PC. Find code, schematics and additional technical info on GitHub: github.com/ffxx68/Sharp_ce140f_emul
FILES command example
มุมมอง 61ปีที่แล้ว
This is the CE-140F emulator on the MBED board processing the Sharp FILES command, to show the list of files on the SD card (two files in this examples). Also shown is a bit of debug info from the board.
Sharp CE-140F emulator DSKF command response
มุมมอง 682 ปีที่แล้ว
The first demo of the Sharp CE-140F emulator, showing receive and processing of the 'DSKF 1' command, returning the emulated disk free bytes.
First complete processing of a disk command
มุมมอง 2302 ปีที่แล้ว
This is the first time I managed to process a disk command on the Sharp PC, receiving back the proper response by the CE140-F emulated on my Nucleo board.
Sending file using serial port
มุมมอง 3.8K2 ปีที่แล้ว
Second demo of this interface for Windows, or Linux, with the Sharp PC-1403. Here I'm using the serial COM port to send the file over to the Sharp. Latest version of the board source code is still found at os.mbed.com/users/ffxx68/code/send_to_sharp. A circular buffer is used to adapt the different speed of the two ends, with serial working at 600 baud and tape emulator around 500 baud (with an...
STM32-to-PC1403 first demo
มุมมอง 1732 ปีที่แล้ว
Here's my first demo of a prototype project to interface a Nucleo STM32 board (an L053R8 model in my case, featuring 32K Flash and 8K SRAM: os.mbed.com/platforms/ST-Nucleo-L053R8/) with my dear old Sharp PC-1403. The aim was just to demonstrate (myself!) the feasibility of such an interface. The Nucleo board is basically emulating a cassette player, by modulating the bitstream with the 2Khz/4Kh...
Renesas tablet JB first demo
มุมมอง 24211 ปีที่แล้ว
This is the first functioning demo of JB ported onto the Renesas tablet platform, to my knowledge. It includes WiFi connection and HW-accelerated EGL graphics (SGX). It's just a short demo to demonstrate the potential of the platform and hopefully will capture the attention of developers who are willing to help, joining our porting project at groups.google.com/forum/?fromgroups=#!forum/renesas-...

As you can see from video, the touch is properly received by the EventHub module, but somehow is not dispatched to the window, which is the locker screen in this case

Nice project you got !
Great Job
Where can I get or build the storage device?
They're not on sale, but I have some remaining (NOT including the Nucleo controller board, which can be sourced elsewhere locally) - where are you located?

Is there an equivalent of INPUT# PRINT# for reading and writing data from the floppy disk or is only load/save of programs supported?
Hi , the commands implemented so far are DSKF, FILES, LOAD and SAVE. I'm now concentrating on the move to the pcb production. I also hope that, with the physical hardware available to more people, some developer would jump onboard along and help with the implementation and debugging. But if you meant whether the original drive supports INPUT# and PRINT#, the answer is yes. See the manual (github.com/ffxx68/Sharp_ce140f_emul/blob/main/CE140F_OPERATION_MANUAL_EN_DE_FR-compressed.pdf)
@@ffxx68 Ah ha! I didn't know where those commands were documented (since they aren't in the main manual). I just got myself at PC-1403 so I'm looking forward to trying out your code on Arduino.
Great idea!
Very nice! I saw the way that you have different paths for the data lines in your schematic. Clever. :) In short order I'll have my first Sharp PC, and I may have to build one of these. Probably less than $50 for all of the parts. Is the Keil compiler free? I saw your note about keeping the +5 volt separate, what about only allowing power in from the Disk Drive emulator so you could save your batteries on the PC? And the NUCLEO-L432KC is the way to go. I did a weigh scale board for fork trucks that transmitted the weight on the forks via an Adafruit 900Mhz Feather board. It also used level converters like what you have. Finding the correct feather footprint for KiCad was a problem, but it wasn't much more than tying the footprints together.
Hi - nice to hear interest in my project! Yes, Keil is for free. I'm using the online version: studio.keil.arm.com/auth/login/. I've also moved schematics to KiCad, but still reviewing it before publishing on GitHub. I've also selected a convenient PCB manufacturer (AISLER, in Europe), which estimated the build with SMD components for 46 Euro, for a single board, 72 for 5 (L432KC excluded; it's about 15 Euro each). But, I'm still reluctant to go, as it's my first PCB make project and I'm not quite sure it's 100% correct. I'm looking for reviewers...
@@ffxx68 Post it when you feel that it's ready and we'll take a look. As for getting it right the first time, I wouldn't know what that feels like. :)

Great news on the progress! Absolutely amazing that there will finally be an alternative to the extremely rare CE-140F.
hopefully I can finalize a pcb version too.. but it's not close yet (support welcome!)
Oh my, that looks extremely promising, my friend!
Excellent!!! This is what many Sharp users are looking forward to!
well done, I have question what do you know about Lua script? Im trying to get some help :) Regards, Marcin
Sorry, I can't help about Lua. But you can try asking, maybe someone else...
Nice! I have done something similar with the TI-74 and TI-95.
New build released. Follow up on our discussion group
First demo of JB on a Renesas tablet, to my knowledge, including WiFi and SGX HW-accelerated graphics, mostly to show the potential of this platform. Follow ups on the project discussion board please, at: groups.google.com/forum/#!forum/renesas-emev-osp
Wow, that's great!. Congrats
