Re: PIC 18F46K22 support

So, I will receive a PIC32 sample in few days, and then I going to buy a PickIt 3. Do you know what is the "basic" schematic to make a PIC32 running ?

Re: PIC 18F46K22 support

I just found that Xilinx FPGAs can "auto-program" just by connecting them to a serial memory through SPI. So I think I can use a 1Mb SPI EEPROM. (does the MM EB006 can program EEPROM chips?) Edit: Wow, FPGA are very expansive :shock: I think that starting with two PIC32 would be not bad :m...

Re: PIC 18F46K22 support

I will use 240x136 resolution at 16bpp.

FPGA looks interesting, I never used this kind of IC. I maybe will use this if it's not too hard to program (is it programmable via a PIC ?)

Re: PIC 18F46K22 support

I think Im going to use two PICs: one designed only to render the framebuffer from its internal SRAM, and another one which works with a parallel RAM, and sends the new framebuffer through SPI. Or maybe using the 2 PIC on the same RAM, but how? Edit: @ Benj: hum okay I see, so it would be better to ...

Re: PIC 18F46K22 support

@JonnyW : My final goal is to make an RC Car (or maybe a drone without mechanic parts, it depends on my lifter researches :roll: ), with an onboard camera. The controller then receives video, and has a touch interface. But first, I'll just make a simple terminal, then 2D and 3D graphics with a port ...

Re: PIC 18F46K22 support

Ok I see, I also found the 18F46K20. I can do a TQFP to PDIP board, but I only have a soldering iron and some unsolder tape to solder the chip on my board. I already thought of using separate chips, but the bus system is too slow. Finally I'm thinking about using PIC32, because it will very powerful...

Re: PIC 18F46K22 support

Sorry but I don't think it has 128KB RAM, but 128KB Flash program memory, right? But it is a 80 pins chip, so I can drive the LCD and the SRAM with the same chip (LCD takes 20 IO, and SRAM takes 29IO), the only problem is that it has a TQFP package, and I never tried to solder this kind of component...

Re: PIC 18F46K22 support

Ok, thank you. Actually I want to drive a TFT LCD that I picked in a Sony PSP. It is really easy to drive (it just has CKL, HSYNC, VSYNC, DISP_ON, and 24 pins for color) and it has 480x272 resolution. Heres the datasheet: http://www1.futureelectronics.com/doc/SHARP/LQ043T3DX02.pdf Currently I use a ...

PIC 18F46K22 support

I'm interested in programming with the 18F46K22, but it is not in the support list of EBlock USB Picmicro multiprogrammer (EB006).

Is there any way to get it working ?

Thanks.
