I2C channel not selectable on ARM?

Post by jlangbridge »

I'm having difficulties when communicating between ARM components using I2C. My master, an F303, can communicate with a PCF8574AP, and blink lights to my hearts content. An ARM slave (F030 this time) can't receive anything. The bus does work, since the IO expander picks up communications, but the slave never seems to see any communication. Also, on the component configuration, I can set my address, the GPIOs, but I can't select the channel (this device has three, and when attempting to do something similar on Arduino, the channel selection is available). Any ideas?

Hi,
Sorry, we don't yet support slave mode on I2C, or SPI, for the STARM families

Thanks for your answer. Is there an ETA to that? For the time being, we can use UARTs, but I have another problem with UART, I'll post that separately.
