Hello, I've had a look at the STEVAL-WBC86TX PCB design and have concerns on the routing over the split plane. The STM Webpage doesnt seem to work for the STEVAL-WBC86TX but ive managed to find the Gerbers. You can see in the images below, the top la...

HelloI think its a config issue with my STWBC86, but im not sure. Im having a strange issue where the CHG pin on my recieve circuit is dropping to 0V for roughly 300us which triggers an interrupt in my system to think that its been woken up. This ha...

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,Thank you for your reply and thank you for the clarity.Do you have a Declaration of conformity document for the EVM? This would be useful to get an undertsand of what will be required for my product.And do you know why the EVM has been taken down ...

Oh the blip also happens when the transmitter is powered from 5V

Hi, Thanks for your fast reply. I already have it set to half bridge mode, but to be sure I've used your attached config.Unfortunatly im still seeing the issue where my CHG line drops very very brifefly every 2s

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
