Customer is debugging 100 kHz I2C Slave connecting to a host from SW_I2C_slaa703a.pdf app note/code.
>>With 8-MHz MCLK, software slave I2C can achieve 100-kHz SCL clock frequency using assembly code and 43-kHz SCL clock frequency using C code.
P. 7 (and my scope confirms 43 MHz SCL clock with FR2111_SW_I2C_Slave coming from FR2311_HW_I2C_Master ), seems to say to use ASM for 100 kHz.
>>The provided assembly code supports only IAR Embedded Workbench IDE.
From p. 8 of app note), looks like the assembly version is IAR and not CCS. Do we have a CCS version?
Have seen posts like the following with people manually converting.IAR assembly to CCS
How hard would converting be for about 400 lines of FR2111_slave_i2c_isr.d43? Just syntax or lots of assembly instruction differences?
[Quick comment. we were able to run an FR2433 version of the SW I2C C code, successfully writing ~83 kHz SW I2C Slave with FR2433 running 16 MHz clock (from the I2C Master FR2311 Launchpad).
So might not need the FR2111_SW_I2C_Slave_withASMcode]
