Re: Low Power 2.4 Inch 128x64 ST7565 Serial LCD Display (HCMODU0245)

This is a nice display with low power consumption of about 660uA, and together with the HCDisplay library easy to use. I have done a quick evaluation using the example given above. The active screen area is less than the screen size and is 1.7"x1". giving a diagonal of 1.9" I have also noticed when ...

Re: 84 x 48 LCD Display / Nokia 5110 - (HCMODU0105)

I tightened the tabs on holding the bezel to the pcb whilst pressing firmly on the bezel. It now works! I think I will solder the tabs in place to make sure. Thanks for the advice. I also noticed by accident that that the display works perfectly without Vcc being connected. Although it takes about 1...

Re: 1.8 Inch 128x64 ST7565 Serial LCD Display With Backlight (HCMODU0246)

Very pleased with this display. Ideally suited to low power applications -
Screen is clearly visible in daylight even without backlight reducing power consumption to less that 1mA.
HCDisplay library simple to use with this device. Thanks

Re: 84 x 48 LCD Display / Nokia 5110 - (HCMODU0105)

Further to my post today. I removed the bezel and noticed that there is no connections between the the display and the breakout board pc. Back of the display itself there is just a rubber pad where the contacts should be.

Here's a photo

Re: 84 x 48 LCD Display / Nokia 5110 - (HCMODU0105)

Thanks for your reply;
I can control the backlight from the sketch in the way you describe. So no compile errors.
Will try again and do what you suggest but maybe I've damaged the device in some way - I am operating at 3.3v using a Pro-Mini so can't have blown the pins.

Re: 84 x 48 LCD Display / Nokia 5110 - (HCMODU0105)

I have recently puchased the NOKIA type B display.
I am experiencing difficulty displaying the example given
I have connected according to the diagram given
I am using the latest version of the HCDisplay library.
Nothing is displayed.
This example works for the type A display.

Re: HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules

I carried out further tests on the HCWireless Libry v1.0 using two Nanos Tx/Rx and the 433Mz Modules. It is possible to assign TXpin to other that pin 8 but not the Rxpin. I have looked at the code and can't see why this is happening. Further to compatabilty with LGT8F32 processors I thosug if there...

Re: HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules

Thanks for the reply. Regarding the HCWirelss library not being able to set the Rx pin to other than pin 8. I have tested this out again using Arduino Nano and your 433 Mhz Rx/Tx modules on multiple pins. the Tx pin can be set to any pin OK but I have tried changing multiple Rx pins to other than 8 ...

Re: HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules

Futher to my recent post regarding using the HCWireless Library compatability with the LGT8F328P QFP32 development boards I have carried out further tests and I can confirm that the HCWireless Library is compatible with this device as long as both the TX MPU and RX MPU are set to a clock frequency o...

Re: HCWireless Arduino Library for 433MHz Wireless Tx & Rx modules

Thanks for the reply. I'll use the RadioHead ASK library with the LGT8 MPU. The board will also be driving a NOKIA lcd display using the HCdisplay libray which it does very well exceeding the the performance of the AVR Pro-Mini.
