k64f lcd panel adafruit free sample

I like to know how is the board connected and connected to which pin for the KL25Z and the LCD display for the LCD to work as i myself got the adafruit TFT LCD

Hi motoo-San is it possible to achieve this oscilloscope by using one kl25z board or I need more than one kl25z board to achieve for the LCD display and the oscilloscope. Is it possible to do with only the adafruit TFT screen.

Hi Moto-san, does that mean that the input signal will be probe for my oscilloscope and the kl25z will be able to power up my Adafruit LCD Dsiplay.Does that mean that the KL25Z is my power source to power up my adafruit LCD. Is it possible to achieve the oscilloscope if i do not connect my adafruit LCD to my KL25z. Can i connect my adafruit LCD display and my kl25z seperately

Hi Moto-san, I have trided the oscilloscope and is able to work, after that i try to connect the function generator that you provide to LCD it is able to work but after some time the TFT adafruit is unable to work for the touch screen is unable to work. is there anything to do to rework LCD touch screen

I have been trying to initialise my Adafruit 7" TFT for some time but no matter what combination of programs and library"s I try I have only ever got a blank white screen at best.

I have been mainly using David Smarts RA8875 library https://os.mbed.com/components/RA8875-Based-Display/ and variations of it. Somebody has made a fork of it for use with the K64F"s but this still does not work. https://os.mbed.com/teams/FRDM-K64F-Code-Share/code/RA8875_KeyPadDemo/

In the area of IoT (Internet of Things), one obvious need is to have a way to send and receive data with an internet protocol. MQTT (or Message Queue Telemetry Transport) is exactly like that: a light-weight Machine-to-Machine communication protocol. With the MQTT protocol a microcontroller (or ‘client’) can send data and/or subscribe to data. For example to the Adafruit.IO:

In this article I show the basic steps to get MQTT running on the NXP FRDM-K64F board using MCUXpresso IDE, lwip and MQTT. lwip ois a small and open source TCP/IP stack which is widely used. To keep things very simple in this first post, I’m using it in bare-metal (no RTOS) mode with no encryption/security. The principle applies to any IDE/toolchain, as long there is a lwip port available for your board and IDE/toolchain. I’m using the MCUXpresso IDE as it nicely integrates with the MCUXpresso SDK which includes a lwip port for the FRDM-K64F.

With MQTT I can publish/subscribe data on the internet. It is light-weight, open source and makes it ideal for any IoT kind of applications. Using it with the FRDM-K64F and lwip took me a while to get things working (I still face some issues in combination with FreeRTOS, so this is likely subject of a follow-up post). Another thing which I have not covered here is the need for secure connections: using an unencrypted MQTT port 1883 is not something to be used for sensitive data. Instead, port 8883 with SSL/TLS should be used. Yet another reason for a follow-up post I think?

To download. click the DOWNLOADS button in the top right corner, rename the uncompressed folder Adafruit_ILI9341. Check that the Adafruit_ILI9341 folder contains Adafruit_ILI9341.cpp and Adafruit_ILI9341.

Place the Adafruit_ILI9341 library folder your arduinosketchfolder/libraries/ folder. You may need to create the libraries subfolder if its your first library. Restart the IDE
