HelloI couldn't find it on the official website of the product.I have download UM2270 document but couldn't get firmware source.Where can I get the source code described in the UM2270 document.Best Regards,J.P Hong
Hi everyoneI'm going to use STLD40D Driver IC for my TFT LCD. For driving LCD backlight, I'v chosen this Driver from ST. But I can't figure out the function theory of this driver. could you please explain for me the STLD40D function theory and how to...
Can LED2472G be used as a shift register to drive signal relays with coil current of < 30mA. Can they be used as generic shift registers too?Thanks!Håvard.
ContextI'm working on building an LED Cube for no other reason but my own self learning. My intention is to use 12 LED1642W to support a 8x8 grid of 3 channel RGB LEDs, with a 13th LED1642W to multiplex the cube's layers. As a minimum viable model, I...
Hi, I have an IC in hand which is written "HVLED01A" on it and I want to know its product number.I wonder is that same as "HVLED001A" product number or it is different IC? Thank you in advance.
Hello,I would grateful for some clarity on the expected bit order when writing to the configuration register of the LED1642GW.Whilst it is clearly documented that CFG-0 is the LSB, and CFG-15 is the MSB of the serialised word, it is not clear to me w...
I have a project whereby I intend to cascade 13 LED1642GWPTRs, in order to control a number of RGB LEDs.As an "in-progress-check", I have currently placed only two LED1642GWs, each as the schematic below, with SDO of the first chip connected to SDI o...
HiWe observe sudden changes and flickering especially at low level luminosity.attached oscilloscope capture_1 is taken at one of green LED channels. During the dimming cycle, the ghost pattern causes momentary flashes in LED brightness.again oscillos...
Testing the LED1642GW using the X-NUCLEO-LED16A1 expansion board. I appear to have the communication working using the digital keys for LE on a GPIO output and a SPI interface. I can read and write the configuration register and write brightness valu...
