Hello, I've designed a PCB with a schematic nearly identical to the STEVAL-WBC86TX. The only modifications are a capacitor and coil size change, which I've also implemented on a development board for direct comparison. On the development board, my ...

Hello, I am using an STM32G061K6T (only MCU I could find in stock at the time) and I'm try to communicate with an EEPROM via I2C.I have the SCL and SDA mapped to PA9 and PA10, respectively with 3K3 Pull up resistors. SDA pin is pulled up and stays up...

When i the touchscreen on my LCD it occassionally presses somewhere else on the screen to where i have pressed.The simulation on touchgfx works perfectly which means it isnt the code ive implemente in the virtual functions. Only assumption is that th...

Hi, I am using a Nucleo F401RE with ILI9341 LCD Display and Touchgfx. I have managed to get the display working with a single framebuffer but the RAM on the MCU isnt capible of handling the full screen size (320 x 240), so i will have to use partial ...

Hi, Yes when the STWBC86 is powered from 5V it works, but only charges at about 60mA. But when its powered from 12V the IC gets to 100 degs then the over temperature protection kicks in.What do you mean adjust the input voltage? Thanks,Mike

Hello. Thanks again for your help. I will send a snippet of my receiver circuit when I am back at my desk (tomorrow) and I’ll also send across the coil information.My receiver is powered from my lipo battery 3.7v nom. I guess this is an issue?The lay...

Hello,Your post was helpful, thank you. I've discovered some interesting results:I was initially powering the development board with a 5V USB supply.My transmitter PCB, however, is designed for 12V operation.When I reduced the voltage to 5V on my tra...
