Hello all, I have a STM32L552MEY6P. I am using it as a slave and setting an address. Using the MX cube set the speed for 400kHz. I have a Rasberry pi trying to do an address detect. Whenever I turn on the clock stretch, I get a read at address 0x50....

Hello all, I have a design that is designed with a STM32. The SWDIO pin and SWCLK pin are pogo test points and difficult to solder wires to connect to the ST link programmer. The design has the BOOT0 pin pulled up to VDD. The I2C lines are the only ...

Hello all, Thank you for the replies and I finally got some updates and was finally able to get back to this. I agree with everyone that the problem was with the level translation. I was able to resolve it. I ended up using a PCA9517 level converter....
