StrangerM got a reaction from bluehash in [POTM] dAISy - A Simple AIS Receiver
OK. Good news. It are some my steps. Your project -> Energia. Tekmanoid->Arduino. And It`s my boat (Stranger :-))

StrangerM got a reaction from bluehash in [POTM] dAISy - A Simple AIS Receiver
Thanks you!
There is a photo of already finished device.
I did the project simply. I collected all C-files in one. So it turned out better because of features of the Energia compiler. I added h-files in the project. I changed interrupt operators and input-output operators. It does not look well, nevertheless the device works. Now the project is disorder and contains errors. Therefore I would not like to publish it, but I can send it to you (as author of the project :-)).
PS Sorry. I collected not all C-files in one. And I added not all h-files in the project. I used needed files from your project. It was in April (or May)and I don`t remember everything well.

StrangerM got a reaction from Fmilburn in [POTM] dAISy - A Simple AIS Receiver
Hi to all. I have made dAISy with 4463. Has carried the project on Energia IDE platform. And I used a differential transformer on an input of the receiver. I have checked up work of the device on a distance about 1 kilometer. The device works.
I liked this idea. The idea is simple and beautiful. ?hicken, accept my congratulations from far Russia. Accept my respect. Also accept my small support in the form of purchase of one dAISy.

StrangerM reacted to madias in [Energia Library] ILI9341 TFT 2.2 port
Ok, I've merged the newer version of the seeed library with the energia port.
Text rotation is now possible, but very disappointing and bad integrated, but for my purposes it works.
Note that the background color of the text wont work anymore, I've included a dummy variable for compatibility reasons.
Modification and an example attached.

StrangerM reacted to spirilis in [Energia Library] ILI9341 TFT 2.2 port
Got my new displays in, and got one working with the same text example... Tiva-C TM4C123GH6PM LaunchPad used here.
Two things:
1. Please include the FastDigitalWrite lib, I didn't have that; I found it over here: http://forum.stellarisiti.com/topic/675-solved%C2%A0launchpad-stellaris-on-energia-miso-erratic-behaviour-on-spi0-and-spi3/ (the SPI_all_ports_LM4F.zip file, I copied the FastDigitalWrite.* files over to get it working)
Looks like @@Rei Vilo wrote this one.
2. The Tiva-C shows as board not supported... Here's what I did to both FastDigitalWrite.h and TFTv2.cpp:
// Board check #include "Energia.h" #if defined(TARGET_IS_BLIZZARD_RB1) || defined(TARGET_IS_SNOWFLAKE_RA0) #else #error Board not supported. #endif Moved the #include "Energia.h" up above, then checked for the TARGET_IS_ definition instead. SNOWFLAKE_RA0 is in preparation for the new TM4C129-series LaunchPad FYI (that silicon uses TARGET_IS_SNOWFLAKE_RA0 in the TivaWare headers).
Anyway, pics or it didn't happen:
Pinout is mostly self-explanatory, Vcc/GND go to the 3.3V Vcc and GND, SCK goes to the boosterpack-standard SPI SCLK pin (PB4), SDO (MISO) goes to the boosterpack-standard MISO pin (PB6), SDI (MOSI) goes to the boosterpack-standard MOSI pin (PB7), then RESET/LED/DC/CS is your choice and you define them in the object initializer statement in setup().
All in all, what a sweet LCD! It's my first TFT for MCU work so I'll be gushing over it. Time to dream up some projects :-) And good work on the port!

StrangerM got a reaction from COSMIC13 in liquidcrystal_i2c library from Arduino and LCD 20X4
I use liquidcrystal_i2c library from Arduino with Energia (10) and LCD 20X4 (from China :-)) for Tiva-C launchPad. The address of my LCD driver is 0X27. I have used in example ( Energia_HelloWorld_20_4_I2C) 2 I2C module (PD0- SCL, PD1-SDA) (default module - 3).
PS Attention!!!!!!!!!!! I changed the lib & the example.

StrangerM reacted to spirilis in PWM changes depending on the code it's running
Ok:
#include <wiring_private.h> void setup() { // put your setup code here, to run once: pinMode(PF_0, OUTPUT); } void loop() { // put your main code here, to run repeatedly: PWMWrite(PF_0, 256, 200, 15000); while(1) delay(100); } Saleae Logic16 shows a waveform with width=52.1uS, period=66.68uS, frequency = 14.997KHz. Pretty close. 52.1/66.68 = 0.781343, 256*0.781343 = 200.02 so that looks right.
Running this:
#include <wiring_private.h> void setup() { // put your setup code here, to run once: pinMode(PF_0, OUTPUT); } void loop() { // put your main code here, to run repeatedly: PWMWrite(PF_0, 256, 200, 15000); delay(100); } ...produces ALMOST the same thing, but every 100ms there's a single pulse whose width is 101.65uS instead of the typical 52.1uS.
Running this:
#include <wiring_private.h> void setup() { // put your setup code here, to run once: pinMode(PF_0, OUTPUT); } void loop() { // put your main code here, to run repeatedly: PWMWrite(PF_0, 256, 200, 15000); } Produces no waveform at all; the signal goes HIGH after Energia starts and then stays there with no transitions.

StrangerM got a reaction from spirilis in Hello from Sankt-Peterburg.
Hello from Russia. I like my boat. :-) And I like to make smart things for my boot. In addition I am old radio-amateur and a scientist (control systems, power inverters of AC drive (not programmer)) :-).
