Hi everybody, I would require some help on an I2C link between TSL2591 and my nucleo nano F303K8T6.
I did it working well on the mbed website TSL2591_F3, but I want to use SW4STM32 environment and also CUBEMX.
Using my scope I can see that on in mbed configuration that I have I2S clk and data that can be decoded :
but when I use my code ( was working fine on e stm32F411re ), I get this signal :
I kept the same time base to show you the speed difference.
I generate my project using cubemx and in the system clock configuration, I have this config :
In the top right corner I can see the I2C clock speed at 8MHz, I would like to change it but I do not find any solution to reach 100kHz.
Can I get the system clock configuration from mbed at any way ?
Thanks for your help.
Well, after a lot of investigation, I had a look at the nucleo f303K8T6 schematic. This board is delivered with straps between I2C and SPI signals, the after removing it, it worked well.
