Is there an IC which converts I2C/ UART/ SPI commands (or any standard communication interface) directly to DALI2 format? DALI seems similar to 1.2k baud UART in a sense, but is encoded in Manchester format and has its own start/stop bits. I'd like to reduce SW development for DALI driver bit-banging if possible by using a DALI-capable chip.
Thanks in advance!
Microchip have some parts that support DALI such as PIC18F26K83 using a modified UART peripheral. You still need the high voltage and polarity insensitive interface circuit externally but this could simplify your design.
Whether this is suitable depends on your application. I believe it can be used for control gear (slave) and for single master with receive capabilities, but if you need multi-mastering as defined in IEC62386-101 then check with them - the data sheet isn't clear how it copes with timing windows defined in the standard.
Infineon has IC's and kits for Dali. Since it is a mix of technology low V uC and AC rectifiers, it's not just an IC.
