I want to know if i can use the STLED524 with 64 LEDs or is the device just working when all 120 LEDs are connected.

I have configured One way authentication mode and able to connect to the server successfully.After getting socket ID, I am using AT+SOCKW command to POST and GET.e.g. AT+SOCKW=00, 18<CR> (18 length is example)POST /api/Frames HTTP/1.1<CR><LF>DATA......<CR><LF>AT+SOCKW=00,18<CR>GET /api/Contracts HTTP/1.1<CR><LF><CR><LF>and in response always getting HTTP:400 Bad request error.Please give a technical person contact number of ST employee, or please suggest solution on this.

Hello,we are using STR73x for our application.We developed our own CAN boot loader that can download our application code ​to the flash and reboot the system.  The reboot works fine.But we decided to change the application codes such that it does not reinitialize oscillator clock selection (CMU block) and does not turn off PLL and relock it again, the CAN fails to work but the UART debug still works correctly at the right baud rate.  we are confused on what may happen.  That is why we want to ask if CAN is configured with MCLK which is driven by PLL clock or by OSC clock.  Can you please let us know what else can impact CAN clock source like that?Thanks,Henry

Hello,How to programme this MCU? What tool can use? Ic no ST10F273-CEA

Lightning surge protection level should meet the standard:IEC61000-4-5Common mode：2kV, normal mode：1kVMalfunction：Level3Destruction ：Level 1Mainly concerned on the PoE PD part and the Antenna part

Hi, I want to use the IDW01M1 under Arduino IDE because I already have the code to scan an UID of an NFC on this IDE and I want to send it with an http request but I can't use the IDW01M1 under Arduino IDE

eDesignSuite is able to provide only the value of the inductance, I would like to know even the value of the resistance at 13.56MHz.

2M2i is a discontinued product?If there is a discontinued product, what is the substitute product?

It looks like on the datasheet schematic that I/O1 and I/O2 are hooked to the same circuitry and therefore can be used as either D- or D+ depending on which orientation is convienent. However, in every example schematic that I have found I always see D- on I/O1 and D+ on I/O2.Can someone please confirm whether I can use either I/O pin for D- and D+?

If I leave all of the PullUp and PullDown pins disconnected does it matter if the USB Connector side data lines connect to D+/D- OUT while the Controller side data lines connect to D+/D- IN?This would be the opposite of what is shown in the datasheet but judging by the simplified internal schematic I think it may make no difference.

Hello, ​I am using the above mentioned Wi-Fi board oIn my project. Wi-Fi security is my concern, because the http server works in MiniAP mode which only has Open or WEP security. WEP can be trivially cracked. Is there any possibility to enhance security? Can I run http server in STA mode with WPA2 enabled. Can the MiniAP be enabled to use WPA2? ​Thanks!

Hi, i'm looking for ST9309 - 137651 Transistor data sheet or equivalent. I beleive this transistor is obsoltet now so i'm searching for an equivalent transistor. This transistor is on my Bose accoustimass powered subwoofer. appreciate any help you can give me.

Worked in burst mode from 50V HV, then lower output voltage till 120VAC input, and almost totally powered off when input VAC above 135V. The ZCD resistive divider is 82 kOhm and 12 kOhm. Transfomer has 100 turns, 7 and 7 turns respectively. Lpri about 2.7 mHn. I tried 1.3 mHn and 0.9 mHn too. The same results.  Why?Did anyone have some problems like that? Is anyone know how to calc an impulse power transformer for STCH02 design? 

Hi,I'm using the STEVAL-3DP001V1 which has a SPWF01SA module on it. The default firmware of the module has some webpages already prepared for the 3D printing application. However I would like to customize these (or even make my own) webpages. In the manual of the evaluation board there is a mention of a gen.bat file which is nowhere to be found in the STSW-3DP001 (the embedded source for the board).So how can I customize or generate a webserver for the SPWF01SA module ?

Hi i have to replace some stripfets part number stp50ne10 they are obsolete and i need a modern replacement they are used for dc 24v brushless moter cotroller

There are our test and verify procedure of defective IC as following:Our terminal client found IC function disabled issues(no voltage drop value and no voltage output) and feedback------- engineer found disabled IC through confirmation and analysis( engineer measured the 1th pin and 3th pin's voltage drop value of disabled IC used multimeter,no voltage drop value display,see Pic1)-------Disabled IC recovery normal function and change OK(when  engineer took down Disabled IC used iron and re-install IC on the PCBA,through iron's high temperature, disabled IC recovery normal function and change OK. engineer measured the 1th pin and 3th pin's voltage drop value of IC used multimeter ,have voltage drop value display,about 0.543V ,see Pic2)------after 48 Hours of aging testing with current of this IC it was disabled again(no voltage drop value display,see Pic:3).Through the above test and verify procedure wh

Posted on February 16, 2017 at 23:54I want to use the STM6600 controller to manage the power ON/OFF of my microcontroller system.
