Well I'm busy now fixing my truck leaking water pump, by the way i did quick test with no wire connected to T_IRQ pin. Screen starts up and work correctly other than no touch of course.:confused:

;) I love it so far. TFT TIRQ interrupt signal must be used for this example. v1.2 Addition: TFT TIRQ interrupt signal. v1.1 Addition: set up touch rotation independent from the screen rotation. //Rotations 1...

Hey Mike glad you are having fun. The touch is probably part of the issue, I bet if you use the T_IRQ pin it will look a bit better.

tft.drawRoundRect(180, 200, 120, 40, 6, ILI9341_CYAN); :D

Hi KurtE I was also busy today printing but this orange piece in the middle ILI9341 TFT front bezel seat.:)

;) from polling gps.Poll_CFG_TP5(true); // Polls CFG-TP5 (0x06 0x31) - Poll Time Pulse 0 Parameters

Oh you must have other GPS messages running like maybe NMEA? in UBLOX.c : // prevent _gpsPayload array overrun error, currently set @ 150 if (c < _payloadSize) { _fpos++; } else { ...

Yeah this is the reason i asked because inside the UBLOX library on last update i did try to implement this functionality with simple gps.USE_Ucenter(true); Command, Unfortunately i was running into issues. If you...

Just wondering how are you connecting to u-Center Software? USB FTDI chip?

I got to see if i can implement the T_IRQ pin that's good idea, reducing the SPI traffic.:D Oh and the orientation for the touch might be a bit more tricky, some of this displays have the touch upside down so you...

I also edit my serial3.c buffer size, maybe this is the start up issue? //////////////////////////////////////////////////////////////// // Tunable parameters (relatively safe to edit these numbers)...

Try uploading one more time or connecting disconnecting the USB cable? You can only get PPS signal with satellite lock (fix type 3d), probably around 4 satellites. One time I was waiting 10 minutes to get satellite...

Hey Mike that's good news.;) I'm assuming you running it with the new GPS that has the PPS pin broken out.

Hey Mike can you give this a shot, don't forget (set up your GPS port and TFT pin definitions). v1.1 Addition: set up touch rotation independent from the screen rotation. //Rotations 1 or 3 = Landscape mode only ~...

I see take a break man, I can't fix this today but you are digging in the right place (it's just the code issue). The change will have to be done in 2 places: 1st. in #ifdef TFTCalibration and 2nd. in ...

Hey Mike no problem thanks, It's my bday today so I have plenty of family over just wondering if you having any luck with the touch part? ;)

Sort of I'm trying:rolleyes:

I can send you one tomorrow if you need one quick i got about a hundred of these 2.8" :D

In kinetis.h @ about line 765 and down. But for testing youre good for now, F_BUS @ 36000000 = SPI @ 18000000 hz EDIT: I got this on my display ILI9341 Test! Display Power Mode: 0x2 MADCTL Mode: 0x2 Pixel...

I am using Pjrc display, note some of these displays are picky about the reset pin. Https://www.Pjrc.Com/store/display_ili9341_touch.Html

Don't overclock for testing, in fact you better off slowing it down. I had issues with long wires and i was also overclocking the F_bus. Run this: void setup() { // put your setup code here, to run once: ...

No, but you are claiming to be a beginner? PCB circuit designing and soldiering doesn't sound like beginner to me? EDIT: And to be specific yes it will work I was just trying to offer the easy way out.

If you're a beginner then get one of this https://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Delectronics&field-keywords=ftdi Just make sure it's the 3.3v version if you're on teensy 3x. EDIT: You got teensy...

Hey thanks for the advice I'm no expert either but it's definitely a fun.:) I guess I'm just going to experiment a bit thanks KurtE, doing this on HICTOP CR-10S printer, we'll see how it goes.

KurtE interesting project you got going here, nice. I am sort of new to the 3D printing, I was just curious if you needed to print any support for the ventilation slots in the prototype box if you don't mind answering....

Thanks Mike. LOL my to do list is like small circular buffer, between my two kids and demanding wife things get quickly over written;).

Hi all For what it's worth I am releasing my quick TP5 (0x06 0x31)Time Pulse Parameters configuration editor based on ILI9341 TFT + Touch interface. It's not perfect, you can only change settings for Antenna cable...

@ defragster Oh that was you thanks, yeah the banner was extremely hard to implement:cool: Well here is one more from Frank B. //...

This is useful sometimes. void setup() { // put your setup code here, to run once: CPUspecs(); } void loop() { // put your main code here, to run repeatedly: }

Well I got ;) this: Not finish yet, will release it later (issues), unless you guys need it now let me know.

Thanks for zipping;), I've been out with the family for a few days.

Mike Nice links. To answer your question no not yet, was taking a power nap except on my keyboard (made a mess;)), had too much fun with the scope. There's a few other things I'm thinking about tweaking before...

Sounds good let us know how it goes.:rolleyes: Be careful hooking up the signal to Teensy, I'm not sure if it's my scope yet or the wiring but i am getting large voltage overshoot.

Yeah that was the idea anyways it's all good LED is still blinking;) I figure if i removed the LED i will not need the resistor so I can solder on top of the entire SMD package.

Support configuration command for uBlox Library added, will release it soon needs clean up. gps.SetCFG_TP5(15, 50.000000, 50, true); // UBX-CFG-TP5 (0x06 0x31) - Set Time Pulse 0 Parameters. // Possible...

I know this is a bit confusing, but I'm not even messing with this (UBX-TIM-TP (0x0D 0x01) Time Pulse Timedata setting). I hope I don't have to:confused: This is the one I am looking into (UBX-CFG-TP5 (0x06 0x31) Time...

It seems I can set the frequency between 1Hz to 24 MHz. Just curious if this is my GPS only, haven't done any scope testing yet. Long story short I'm trying to add support configuration command for uBlox Library...

Pin change interrupts There are two ways you can detect external events on pins. The first is the special "external interrupt"on the Atmega328-(Arduino UNO) pins, D2 and D3. These general discrete interrupt events, one...

Just to let you know the Teensy 2.0 (ATMega32U4) has 4 INT External Interrupt and 8 PCINT Pin Change Interrupts. Add Interrupt pins to Teensy 2.0

Hey guys i know this is a bit off topic but it's too funny not to post. My first master and slave SPI implementation on ATmega328P. I even had a nickname for this ( MonsterSlaveDuino ).;)

I've been doing this for about 2 years already but between ATmega328P Slave and Tennsy 3.6 as Master. Of course the ATmega328P can only handle 4Mhz SPI communication.:( The part responsible for SPI communication on...

All good points except my first two (Serial1-Serial2) are already busy with my custom UART implementation (not much left from the Teensyduino implementation). I'm using Serial1 for Chrysler--CCD (Chrysler Collision...

Whoa that's a good catch thanks man.:eek: It could have been an ugly bug to find later on, lucky me there is not too many messages exceeding 255 bytes

Yeah it does look interesting so far.;) I will try faster baud rate when i have more time. TX bytes @ 89576358 no errors I'm thinking about implementing Monitoring Message command ~ UBX-MON-IO (0x0A 0x02) I/O...

Sounds good tanks. I don't believe it's Teensy issue here, i believe the limiting speed is the GPS Hardware here. Ok so I've been running stress test of this 1500000 baud rate. Basically i used u-center and enable...

No problem As far as the division I'm not sure without the hardware it's hard for me to give you advice on this. In the post that you show the error the Teensy 2++ appears to be running on 8 MHz Perhaps you should...

Your defining the pin as 45, I'm not sure if Teensy 2++ has that many pins? Edit this 1st ok Connect the sensor to pin PD0 Edit this: #define RG11_Pin 45 to #define RG11_Pin 0 this is correct

Okay i don't have Teensy++ 2.0 but they are based on AVR MCU which i believe you have limited number of interrupt pins, unlike Teensy 3.x series, all pins have interrupt capability. You should use only PD0, PD1, PD2 or...

Update #3 Ok so finally i had time to finish up this work-in-progress ver.1.0.2 @ Mike I hope you still around i did manage to implement the commands CFG-NAV5 (0x06 0x24) and CFG-RATE (0x06 0x08) Gps.SetNAV5(3,...

? The highest SPI speed you can get is 60mhz, this is on teensy 3.6 runnning @240mhz with F_BUS speed set @120mhz .

Woah lots of good info in the links you provided. Unfortunately life is getting in the way, so far i only got the CFG-PRT (0x06 0x00) implemented properly. Thanks.

Perhaps this is a dumb question, is it possible to run T3.6 as slave @ 30 megahertz SPI if the F_BUS is running @ 120 megahertz ?.
