POWERAVR NXP LPC1768 board

very useful man. I have the same board and didn't come with a manual.

@madpuri Thank you. Please do not hesitate if you have any questions regarding the use of the board or how to program it.

hello dear i m new 1 i want to switch to arm processor from 8bit controller i only want to see that how you transfer program to board and which compiler you are using. i m interested to see your computer screen when you transfer sample program to board

@assad3345 Thank you for your interest in our development progress. It's great to hear that you thought about chaging to 32-bit microcontrollers, though unfortunately you can't "swab" to another processor, using the same code, without making a good amount of changes - especially not when going to 8-bit to 32-bit, as you have to take care about optimizing too. With this board we use the uVision C compiler from Keil. This compiler is very flexible, and supports many different processors.

Awesome Review.

Hi, I have same board but I cant program it by using usb. I dont know what I´m doing wrong. I would want to know how to see the memory program of LPC1768 in my PC, like a mass storage device. I tried it by connecting usb_device (CN12) to my PC, and selecting D- and D+ jumpers but it doesnt works. Could you please explain to me step by step how to do this? Thank you in advance.

@gma90 You would have to download, compile and program the "LPC1700 secondary USB bootloader" on to the chip :)

@mindthomas thank you midthomas. I have send you a private message, please read it.

Beware: The most important informationon on the CD about this board is written in chinese.

@madpuri: There is a manual but in chinese language only

Hi mindthomas and thanks for awsome video review! But I'd like to ask you can 1768 motor control functions be used with this board or there is special development board which has motor driver interface?

Thank you. The motor control feature in the LPC1768 and similar is simply an expanded PWM subsystem, so yes you can use this board for motor control development. Though there are no specific motor connectors on the board you still have access to all the I/Os and therefor you can easily connect the board to your motor driver circuitry.

Very Nice review...

I agree to disagree, I believe the most important document you need from the manufacturer is only the schematics. Once you have that all you need is the datasheet for the microcontroller "LPC17xx User manual" from nxp. You should also visit ARM website to learn about the Cortex-M3 processor (datasheet) core and Thumb-2 instruction set. If you implement (learn) your design that way, you will have a deeper understanding of what you are doing than looking at examples written by somebody else.

@mindthomas Hi Thomas, you mentioned the board contains a JTAG connector but it is not needed because it contains J-LINK chip. Is it possible that it to debug other targeted board? what I am asking is can we debug other board using the onbord J-LINK via the JTAG connector?

Hi. Yes it should indeed be possible. According to the schematic all of the JTAG lines from the on-board J-Link chip is actually connected to the JTAG header thru a series of 120 resistors. The the JTAG header connections go to the chip itself thru a series of 0-ohm resistors. You could have a try and see if you can manage to program an external chip with the JTAG connector without having to modify anything. Though I think it would be necessary to remove R36 to R42 (0-ohm) to get it working.

Hi Thomas I am using the LPC 1769 for a project with Nintendo DS TouchScreen and a PHILIPS LCD Graphic Display PCD8544 (used in Nokia phones). Appreciate if you could help me to make these devices work. Best Regards

Hi. Well the PCD8544 is a common but simple display that was originally used in the well known Nokia 3310's. It is actually pretty simple to control with simple SPI-a-like command writes. Please have a look at the following page where you can find a Arduino library for the display. It should be straight forward to port this library to the LPC1769. ladyada.net/products/nokia5110/ Regards Thomas

Hi Thomas.... Yup, I've look through the link given. I do not understand why straight-forward porting from Arduino Library is possible in LPC1769. They are using different types of codes, am I right? Could you guide me bit more ? Another one is the Nintendo DS Touch Screen, which I need some of your experience to guide me too ? Thanks alot. Best Regards

I own the exact same board! The contents of the CD were sketchy though...

Hello , very nice demo I just ordered a board . and waiting for delivery but i am very new to embedded programming . can you tell me . if i wan to put my own program what compiler will i have to use and where i will find some sample program for this device . I am mainly interested in making an internet search facility for websites .you think it a good idea for making some thing like on this device.

Please explain what you mean with "internet search facility"? Are your idea to be able to use the touch screen on the board to search the internet, fx by using Google? As you can also see in this video, the board comes with a great range of demonstration projects - from simple LED blinks and button press projects to more advanced RTOS projects with Touch LCD support.

Any gui package disponible for LPC1768?

Are you thinking about any specific library? Regarding regular LCD use there is a library for the display that comes with the example codes. But by using the uC/GUI library you definitely get the full GUI experience with Touch options and cool graphics and windowed applications.

Hi Thomas, I am just practising LPC1768 board but having a problem. I load a USBaudio.hex file from code samples that attached along with the board but the windows not regconized. Please release a advice let me know how to solve it? Regards, Huy Tran

Hi Huy. I am not aware of the problem you are describing, but maybe you could try and give some more specific details on the error you get on the computer? Have you tried debugging the microprocessor code and see if it halts/hard faults anywhere? I have uploaded the HEX file I have compiled for the board. You can download it here: tkjelectronics.dk/uploads/usbaudio.hex Regards Thomas

Hi Thomas, Thank you for replying. That meant is i have tried connecting between LPC1768 board and PC but the PC have noticed that "the device not regconized" at on the right under corner of the screen of PC. Please let me know The LPC1786 board have been gotten any driver to run USBAudio? Thanks. Regards, Huy Tran

Hi Huy. Have you remembered to set the proper USB jumpers on the board to enable USB Client functionality and NOT the USB Host. I remember there are at least one jumper that has to be changed and set properly if you have been using the USB Host mode before. Regards Thomas

This video is a good introduction. Would anyone be able to point me to some instructions on how to program the LPC1768 via the on-board jlink using the keil software? I'm having difficulties finding good reference material on how to get started. Thanks.

We are programming the board with the on-board JLink using Keil. Please have a look at our written review about the board, where we also describe how to program it with Keil: blog.tkjelectronics.dk/2011/09/review-poweravr-nxp-lpc1768-board/

You might be able to compact it all and make a real pipboy! :D

Hi mindthomas: 
Thanks for the instruction video.
But I have a problem on updating my firmware now. It's not working when I short pin 1,2 on jumper JP10.  And short pin 1,2 on JP11 JP9.  My computer cannot detect any USB device in such condition. So, could you give me any suggestion?    

Thank you very much.     

Is the documentation in english or in chineese  or mixed in english and chineese
while the mixing is done in the following way:

The unimportant things are written in english and the important things are written in chineese. ?????????????????

A good documentation of such of such a big board in a good englisch has a value of 500.- Dollars. allone for the documentation.

Did the ST-Link JTAG Debugger work with this board and IAR Compiler ?

Thanks for the video. where can I download the examples for my board.

hello, im searching since months for a graph fonction to show my ecg signal on the display of this board(lpc1768)...i need some examples to represent a graph on this board.
thanks u guys for answers

@mindthomas please help me please...do you know how i can converter my ecg analog signal do digital on this board(lpc1768)

can this board be programmed using USB? Or does my computer need a RS232 serial port?

Can this board be programmed with the arduino IDE ?

i bought this board the cd content is in chinese....any one have the english content....

Great video. But the written Review from WayEngineer doesn't have the zip file you mentioned

i have an ILI9846 and everything I write to the display get's displayed as i'm writing. how do you only update part of the display? it sucks because everytime I do a clear display it flashes black. I made and wrote my own library. but it doesn't turn the CS on again until it's done. it's a 16 bit parallel interface. this is the same right?

Can you please tell me where I can buy this board?

I really need that board. It is discontinued in the market. But may be someone have one to give or sell . I'd be very very thankfull. to be sent in west africa.

I am very interested in purchasing the LandTiger V2.0 LPC1768 development board. However, I have been unable to find a reliable supplier or any available stock online.

Would you be able to recommend a trusted supplier or point me to someone who might have the board for sale? Alternatively, if you know of anyone who would be willing to sell their board, I would greatly appreciate the contact information or any assistance you can provide.
