DISP102 PCB DispIDC-20 TFT13

DISP102 PCB DispIDC-20 TFT13. My camera doesn’t do the 1.3″ IPS display justice, the display is sharp and crisp to the eye.

This is a 1.3″ 240×240 IPS display, connected by ribbon cable, instead of the onboard 1.8″ 160×128 TFT display. This enables the DISP102 PCB to support many different SPI displays, and creates options for physical arrangement.

We are calling the off board display connection format DispIDC-20. Options include :

  • 1.8″ ST7735 TFT 160×128
  • 1.8″ ST7735 TFT 160×128 with touch panel
  • 1.3″ ST7789 IPS 240×240
  • 2.0″ ST7789 IPS 320×240
  • 2.4″ TFT 320×240

The DispIDC-20 connection enables a number of different display configurations – see the product page for further information

DEV010B STM32F091RC OLED Development PCB

Posted on by

We are developing smaller HMI for mobile plant that doesn’t have the luxury of space for large operator interface displays

The DEV010B was designed for an OLED display (SEPS525 160×128 colour OLED) such as a UG-6028GDEBF01

The board include a boost converter for the OLED and FPC connector

Pictured here with a driver for a TFT ST7735 160×128 display (we are looking at the display options for our DIN001 and DIN002 distributed system controllers)

The DEV010B has 8 pin JST SH for development with the JTAG and Boot and bootloader UART pins available, and separate headers for SPI2, IIC1 and IIC2 and UARTS (including UARTS with RS485 EN signals)

BLE CC2650STK Development – Switch Contact Monitor

Posted on by

bit of an update on BLE – voltage free switch contact monitor – low power – with contact wetting boost circuit

We are using the TI CC2650STK and have a small development board with our boost circuit. We are using periodic monitoring to have a low average power consumption. Depending on the setup – up to 5 years on a SAFT LS14250 cell.

 

BLE001_SwContMon

We have setup a contact state and click counter, and have the data in the advertising, so no connection required to obtain data.

BLE001_SwContMon_EvoThings_Advertising

We will put up a board design for this application soon.

Current Measurement – Wide Dynamic Range

Posted on by

We needed to measure the current consumption of the wireless IO points we are developing using the CC2650 and CC1310.

We decided to put together our own device that uses multiple LTC6102 devices – one setup for µA and one setup for 100’s µA.

The Headers suit the TI launchpad configuration, the target is a TI TM4C129E Launchpad with Ethernet Interface. The TM4C129E has a fast ADC, sampling at low MHz is possible.

STM32F405 PCB (CORE405R Host for DSP DEMO)

Posted on by

New PCB design for a new potential job demo.

(Two Way Radio SELCAL / 5 TONE / SEQUENTIAL TONE decoding and encoding)

Using a STM32F405 for its floating point (using DSP for this application)

In this case we are using a Waveshare CORE405R PCB (I can’t buy the parts that cheap, and their board already has the basic support ready to go, big time saver for a demo)

includes support for

  • micro SD card socket
  • USB host socket
  • D25 for IO for the demo (RS485, 2 analog inputs, 2 analog outputs, 2 open collectors / drains, power supply)
  • expansion IDC (for anything else later)
  • 320 x 240 TFT lcd (ZEAL 2.2″ TFT module) (under the PCB)
  • IIC user switch and leds next to the TFT (under the PCB)

I have ordered 10 boards, only using 3 so far

Will exchange a board (just the pcb – no parts) for a coffee if you are in the Sydney area

Temperature Monitoring System on Mobile Machine

Posted on by

Starting on a new project.

A Temperature Monitoring System, on a mobile machine (a civil engineering machine in this case), with a LED Matrix display for the operators, and hand held control device for the owner / supervisor.

The system will be developed in phases…

  • Phase 1 monitor 5 Temperature Points (PT100 sensors) and display colour bars and top temperature
  • Phase 2 addition of a hand held monitoring / setup device for the machine supervisor / owner
  • Phase 3 data logging (download through handheld device or by PC connection)
  • Phase 4 addition of flow and pressure sensors
  • Phase 5 valve control and process control decreasing the operator load

To shorten the development cycle we will be buying in RS485 modbus modules for the IO.

The Controller (Modbus Master with 3 RS485 ports, Ethernet with internal switch, CAN port) and the display controller are being developed in house.

We will put up some more information as the parts come in and the system develops.

CC430F6137 433MHz CC1101 Radio Networking

Posted on by

Hi All

I have been using the CC430F6137 for 433MHz network development lately

The boards I found to develop with are from AliExpress (search for CC430F5137 development board, look for the seller King Lei, and ask for the CC430F6137 433MHz demo board with the prototyping pads and footprints under the board, as shown below)

Making it an easy start into CC430 development.

 

 

Led Matrix Display

Posted on by

I picked up some colour LED modules for daylight readable displays.

From Aliexpress Store Shenzhen LCCL Opto-Electronic Science & Technology Co., Ltd.

Shown below driven by a LPC1768. (The normal commercial application uses FPGA to handle an array of these display to build a large screen)

The displays use a serial -> parallel led drive, data in is 6 bits wide (2 rows clocked in at once, RGB), and uses two 74HC138s to select 2/32 rows. This appears to be a fairly typical arrangement for this type of display. (the smaller displays only clock in a single row, but the principle is the same)

AliExpress Colour LED Display Module driven by LPC1768 The display shown is a P4 (4mm pitch between pixels), P3 is also readily available.

I intend to enclose this in an IP rated box with a few basic IO and RS485 and CAN ports.

There will be a single screen and a 3 screen version (That would be a LPC1768 for each display) giving a 96 pixel x 64 pixel display.

Please contact me if you would like any further information.
