This past few days, I unboxed the MKR1000 and was able to get it to connect properly to my laptop and check it via the Arduino IDE.
LED blinking so that's a good start!
I uploaded a library I found to blink the LED for one second and then off for one second so it looks like a fade of light on then fade light off. Its actually pretty cool compared to the blinking LED.
It worked so I verified that I had the correct COM port, that libraries are able to be uploaded into the device and that it executed code properly on the MKR1000.
I have done quite a bit of research on how I will use the audio on the SD Card.
Whatever I create, I will have to make WAV files so I will have the files converted to this format.
Bit Resolution - 8 Bit
Sampling Rate - 16000 Hz
Audio Channel - Mono
PCM format - PCM unsigned 8-bit
I want these settings so they do not require hardly any space and coming out of a piezo speaker, I want to test how it sounds and see if I need to put an audio amplifier.
I have considered a device that has a built in head phone jack, volume control and it also has record, play and stop buttons on it.
When you have a headphone plugged in, the speaker is muted and when the headset is unplugged from the jack, the speaker is enabled.
I think being able to control volume is very important depending on the location that the device will be used.
Don't want it blaring in a quiet area like a library or not being able to be heard if the device is in a store where it can get noisy.
I will update further as I proceed on this part.
I recently ordered a 5" TFT LCD touchscreen and adapter to connect to the MKR1000 that will display the images.
Next is connecting the SD card TSX00004 SD Proto Shield.
I will do that within the next day or so and update you all on the progress.
This past week I also have been researching a GUI that will run on this Arduino device.
I am thinking C# or JavaScript code to create the interface so it has the following:
Option 1.
Have 4 buttons across the top with a different image in each
Have 1 large button across the bottom with a specific image
Option 2.
Have 1 large button on the left side of the screen
Have 4 buttons on the right side of the screen with a specific image.
If anyone knows of any GUI generators that work on an MKR1000 or have any suggestions, I would appreciate the feedback.
I will post another blog this coming week one what it will look like. I get the LCD on the 19th.
Thanks for reading this!
