About the I2C of STM32F030C8; from the datasheet, PIN 42/43, 45/46, They all could be I2C1; pin 21/22 or 35/36, which is I2C2?
please review the datasheet,--4 Pinouts and pin descriptions-- from the datasheet, both PIN 42/43 and 45/46 could be I2C1; both PIN 21/22 and 35/36 could be I2C2; which is right exactly?
