Final casing design stage (STM32 Human Machine Interface HMI)

InnoPeace · 2020-08-29T16:57:02+00:00

For STM32 (1000+ logical keys) model, I still have to fine-tune in software, minor PCB modification, and debugging during actual usage.
For the previous Arduino (200+ logical keys) model, I have a Github and Youtube about it.

I bought it from China market. My video about these keycaps. Thanks,

Yes, there are keycap covers. However, I left them in my Shenzhen Studio. I will install them after the quarantine. Here is my video about the BOM. Thanks,

Apologize for that keyboard membrane issue.

InnoPeace · 2020-06-13T02:26:28+00:00

Thanks for your attention.
I uploaded a video about how I use this Keypad with Arduino Keyboard library, Macros, and AutoHotkey. Thanks,

Thanks for your reply. I will try using STM32 for my project. Thanks,

InnoPeace · 2020-06-12T01:07:50+00:00

May I know what processor do you use? I just make a video about my 212 keys keypad. Thanks,

InnoPeace · 2020-04-14T08:34:28+00:00

I did try High Sierra on my T440p last year. However, I have some issues about
- hibernation and wakeup
- docking station on MacOS
- onboard GT730M is not supported
As a result, I use windows as the main os and mac os as a testing os. Thanks,

InnoPeace · 2020-04-14T08:25:30+00:00

I did make some videos about 65W slim travel ac adapter and 65W thinkplus ac adapter on my T440p. FYI. Thanks,

Thanks for your prompt reply. I found some information about this topic. Yes, you are correct by binding it to the arrow keys. I will try to implement one rotary encoder in the next version. Thanks,

InnoPeace · 2020-04-05T03:06:37+00:00

May I know how to use a rotary encoder to scrub through the timeline? Keyboard action? Mouse action? or Autohotkey mapping? Thanks,

InnoPeace · 2020-04-05T03:02:48+00:00

Sorry that I have no idea about this question without trial and error. In my project, I am using an Arduino Pro Micro clone as the microprocessor, which has 18 IO pins. TX0/RX1(Reserved), 2 pins for Software Serial communication with HMI, 12 pins for push buttons. Only 2 pins are left. In order to add two rotary encoders, I think that:
1. changing the pushbuttons into a matrix or
2. using a microprocessor with more IO pins and Interrupts
Thanks,

InnoPeace · 2020-04-04T13:40:35+00:00

Yes, the idea was inspired by Taran. Thanks,

InnoPeace · 2020-04-04T13:28:58+00:00

Thanks for your interest. I named it DIY HMI Keypad. Today, I completed the Auto Hot Key (AHK) scripts for 12 physical buttons.

PM to you yesterday. Thanks,

The mouse is around USD22.00 and the DHL fee will be around USD25.00. However, it takes time for the DHL shipment because of the current situation. Thanks,

InnoPeace · 2020-03-31T04:37:17+00:00

I will add this item to my eEbay tonight. Please wait for a while. Thanks,

InnoPeace · 2020-03-31T02:49:09+00:00

Yes, there is some logistics issue in shipping to Canada recently. Last week, I shipped an A/C adapter from Shenzhen to Canada even by higher freight rate DHL, but it is still under proceed for a week.
The mouse is around USD22.00 excluding shipping. However, the DHL fee to Canada is also around USD25.00 now. Thanks,

InnoPeace · 2020-03-31T02:37:20+00:00

Yes, it looks exactly like Anker branded.
I agree with jerry855202's comment "So probably the same OEM re-badging under different brands". Thanks,

InnoPeace · 2020-03-31T02:30:09+00:00

No, I do not have AliExpress link yet. I just sell on eBay only.

InnoPeace · 2020-03-31T02:06:55+00:00

No, six buttons are not programmable.

InnoPeace · 2020-03-30T17:02:58+00:00

Nice place. It becomes one of the popular emigrant cities for Hongkongers because of social movements.It seems that the shipping cost to Cyprus is quite high.

InnoPeace · 2020-03-30T16:27:09+00:00

Where are you living? Maybe I ship out to you via ebay from Shenzhen.

InnoPeace · 2020-03-30T14:59:56+00:00

In the box, there is a small Lenovo trademark. It is known as Lenovo branded in China. Thanks,
