Dear Experts,I am using a USB3300 chip as an external HS 480Mbit/s USB PHY with STM32F446 MCU. Using CubeMX to generate code and add USB CDC Middleware. As I connect the USB Cable from the PC to the USB3300 chip no COM port is detected. Didn't find ...

Hello,Is there any documentation or source code to use ULPL with USB3343? Even I am not cleared USB3343 chip could be used for external High-Speed USB support to STM32F407. Or suggest me any chip with low complexity, I aim to achieve high-speed data ...

Dear Experts,I need your assistance. I am attempting to change the memory address of DMA2 during runtime. I am streaming ADC data through UART. The ADC operates at 10MSPS using Timer1, and the tim1_up event triggers DMA2 Stream5 in circular mode. My ...

Dear Experts,I have 4 inch RPI LCD 480x320 SPI based on the ILI9486 display driver. Like inside ArduinoIDE, there is a Library manager where we can find so many TFT-LCD libraries with STM32 board support, Is there a common place to find libraries for...

Dear Experts,I need your help, I am interfacing 16-bit DAC LTC1668 50MHz with STM32F411CCU6. I have used Timer 4 as 1MHz CLK for DAC, on Half Pulse Complete interrupt I update the GPIO Port (Port A A0-A7 are D0-D7, Port B B0-B7 are D8-D15). But Facin...

Hello @FBL I couldnt understand how clock is not operating accurately. I took measurements of clock it is 60MHz and with nearly 50% duty cycle. As my oscilloscope bandwidht is 100MHz it can't measure accurately. So, what is the option now?

Hello @FBL According to the datasheet of USB3300, the CLK pin is only an Output pin. The Vdd voltage is 3.3v.I have attached the waveforms of CLK(Yellow), DIR(Purple), NXT(Blue), STP(Green). This time I used a 10x probe and my scope is 100MHz. Here b...

Hello @FBL I have checked that there is no activity on DIR, STP, NXT, and Data pins of ULPI.I am getting the Clock signal of 60MHz from the USB3300 Chip but it's not the proper squarewave. When I connect it on the PC the USB Device is detected but wi...

Hi,I think FT232HPQ IC is a good start for the person who is new to USB protocol. With this chip, STM32H7 could be used?

Hi,No, I don't want to stop the data capturing from ADC.Why external ADC? Because I need a Higher sampling Rate of 10Msps 20Msps 30Msps. For now, I am working on 10Msps.Sorry to change the topic, but I am working on a data communication system. I hav...
