FT800 XMOS
Ok did a couple more test. Learned the hard way about the swap.. Basically on the FT800 you have to swap out the new screen for the old one. So if you plan to update just a portion… you might have to rewrite the entire screen. Well this is what it seems like right now. Perhaps im doing it wrong.
Im doing this from scratch and without using any functions from the FTDI code, only the definitions.
But so far its pretty good i guess… now to play with TOUCH and actual IMAGES!
Code for above (well MAIN code)
int main ( void )
{
init_ft800();
BeginBITMAP();
FT800_STR(10,10,0xFFFFFF,31,"Jason Lopez");
FT800_STR(10,60,0x00FF00,24,"AtomSoft.wordpress.com");
FT800_STR(10,86,0x0000FF,22,"XMOS startKIT 1V2");
FT800_STR(10,104,0xFF0000,22,"FT800Q Display IC");
FinishBITMAP();
while(1);
return 0;
}
Finally
Could it be?!?!
After some modifications to my board and finally got it working. Ill post details in the morning
Running on StartKIT from XMOS!
2.8″ TFT on XMOS
Ok ive had this TFT from RadioShack for a while now and never really use it but i think this is a good time to test it out. Im using the startKIT from XMOS as the controller.
This LCD is originally a 5v product. To make it a 3.3v item simply remove the 3.3v regulator and jump the input and output pins like I have done here. Notice that in case i want to use it on 5v again i left the IC (vreg) taped to a area on the pcb as to reuse it 🙂
Using the code attached/linked below you can control your LCD as well. This code was converted from the original code from the LCD Info link below. There is no TOUCH portion as of yet. I got tired and decided to leave it for another day. I will be using an IC to convert touches. The IC i will be using is the ADS7843. So expect code for that one of these days.
Here are some images as proof of code working.

XMOS Remote Test 3 – Wireless (Bluetooth)
Now with bluetooth as wireless com and status led to show a incoming signal (D1 on STARTKit) . Works better than i hoped… the PCB has a 3.3v regulator on bottom to drop down the 3.7-4.2v lipo… its a LDO Regulator.
Here is a video, enjoy!
XK-1A Development Kit
It has been a few years since i talked about XMOS and i finally decided to order one. I ordered the XK-1A Development Kit.
The XK-1A is a low cost development board for exploring multicore micro controller designs based on the XS1-L8-64 multicore microcontroller. Multiple XK-1A boards can be linked together in a chain and two I/O expansion areas are provided for connecting additional components to the XK-1A. Design files for example add-on boards are available, including an SD card reader, a Bluetooth adapter and a Control Card.
The XK-1A is available as a kit with an xTAG-2 debug adapter that can be connected to the XK-1A to provide a JTAG interface to the board from a PC, or as an individual board if you want to chain multiple XK-1As together (one xTAG-2 can be used for several boards).
Features
Single XS1-L8-64 device
400 MIPS
8 cores
64KB RAM
8KB OTP memory
128KB SPI FLASH
Four user-configurable LEDs and two push-button switches
Two 20-way XSYS connectors for xTAG-2 debug adapter and additional XK-1As
Two 16-way IDC headers for connecting additional components
24 I/O user expansion
The XK-1A can be powered directly from the xTAG-2 connector or from an external 5V power supply.
That was taken from the XMOS site. I have no EXACT projects in mind for it but for a 8 core MCU it will be so fun to tinker with.
I do plan on getting some bare MCUs and making my own development pcbs. I had to cut out this image from the PDF of the XK-1A for me to print clearly. Its the schematics.
I should have this in this week (Wednesday) or at least i hope Fedex works on time 🙂
XMOS no more…
I decided to forget about XMOS. I decided to go with ARM. ARM seems to be a nice budget choice. Especially in these bad times. A ARM IC can cost as low as $3. XMOS minimum is like $7. Also the ARM programmer can be made or bought for under $20. (parallel) The XMOS programmer is $50 minimum.
As you can see the price is important. ARM speeds are great but harder to implement parallel type code. But the price is main thing right now. So ARM here i come..
XMOS
Ok enough is enough. I have spent tons of money on little things. I want a XMOS !!! Instead of me saving my money to buy it, i end up spending it on little things which im sure i dont really need.
I plan on saving as much as possible and ordering a XMOS XK-1 and some bare XMOS uCs. This time im serious. So far i have $0 Saved lol.. its funny right? yeah…
Anyway i will save up $120-$130 for the XK-1 and some XMOS uCs and parts for it. Lets see how long it takes.
