Hi,
Are the LEDs bar-graphs all in series (numbered 1 to 100) ? or are they 5 separate bars of 1 to 20 each ?
For a 1 to 100 configuration, do you need a bar (multiple LEDs lit at a time) or dot (single LED lit at a time) type indication ?
Regards,
Smokey

How do I display the audio level from the Line-In port of my PC Sound Card on a real time bar-graph display on-screen ?
I have read that some sound cards / chipsets support a feature to read the digital value of the audio input level directly. Not all sound cards support...
As far as I know, you cannot run the MSP430F149 at DCO freq. as low as 32KHz. For this low frequency, you need to use a Watch Crystal (32.768 KHz) on the ACLK osc.

Are you triggering the INT on the right edge ? It cannot take 100 clks to get from port pin change to start of INT routine - it looks like your INT is configured for rising edge while you are looking at Falling edge (or Vice versa!)

Hi,
There is a company in Taiwan called Yuan Dean Scientific. They have a range of suitable products - incl. an RJ-45 with built-in LEDS and Magnetics. I have used their product. However, I do not know if they have a version with LEDs & WITHOUT magnetics. Maybe you can try. The contact person...

Thanks !
I have seen this app note from Philips before.
For this project, I am looking for a 'C' version (preferably written under Keil51 V7.x). I need to embedd the code as part of a larger firmware. I would like to use the PC-Keyboard Interface as a separate...
keyboard interfacing with 8051
Hi!
I am looking for a ready to use 'C' code (Keil51 V7.x preferably) to interface a standard PC AT keyboard to a standard 8051 micro.
I plan to connect the Keyboard CLK line to an Ext. Interrupt on the 8051. and sample the data line (on a standard port pin with...
There is a company in Taiwan that makes a range of RFiD tags & readers. Te company is called Goldkey : www.goldkey.com.tw
However, they sell their products via dealers. One of whom is www.sunbest.com.tw
I have used their products. They are quite good and reasonably priced.
The RFid Tags are...

It looks like a lot of mfrs are waiting in the wings to launch their own module version of CSR and Broadcomm chipsets. Most of them are at final testing stage.
TI is joining the fray with a super high integration single chip solution - priced at uS$ 4.00 for 10K...

Hi Phil,
It looks like you have some inside info on what's cooking at CSR ... in this regard do you know the status of the BC-2 Class 1 solution ? is it ready ? released ? ..
I need a class 1 solution for the extra range (100m). I am not able to find a BC-2 solution...
bluetooth bluecore01m
Hi Yellowtooth !
I gave up on the idea of a GSM Antenna on the PCB - used a regular L-type whip antenna - works well - project completed - everybody happy !
On the Bluetooth front, I want to use the bluetooth module as a black box - I have read the BlueCore Serial...
bluecore02-external datasheet
Hi guys,
I am embarking upon an experiment with CSR BC2 module using the UART interface. I know of many applications / drivers that use the module under win98 / linux. My application requires the module to work with an 8bit MCU (8051).
Is there a simple set of...
Sorry, the last sentence (in my last posting) was not complete ..
" ..we have a number of customers interested because of our low cost solution (HHT + GSM = < US$ 250.) "
