I am working on a project using the STM32F407. I am using the CMSIS drivers for most of the peripherals as well as using CMSIS-RTOS-RTX and the MDK-ARM Network Component. I need to use one of the I2C peripherals with a master/slave protocol. The I2C needs to be able to send and receive variable and unknown length messages to other STM32 devices. When sending the device acts as a master and when receiving it acts as a slave. The protocol already exists and cannot be changed to include the message length so I cannot use the CMSIS driver (it needs to know the message length for the slave receive functions). I can achieve what I want by using the STM32F4 Standard Peripheral Library but this doesn't seem to be directly supported by MDK-ARM. How can I use just the I2C part of the standard peripheral library alongside CMSIS? Any help gratefully received!
Hello, as far as I know the Standard Peripheral Library is no longer supported, now they use the stmcube library that also has a driver for I2C but its different from the one that used to be on the Standard Peripheral Library. You can also use the old versions of the stm support pack and the old cmsis pack they both support the Standard Peripheral Library.
Hope it helps,
