Hi,
I want to use the F28069 piccolo stick for real-time Ethernet applications with IEEE1588 clock synchronization.
Until now the only two ethernet controllers which can handle it are the 2 mentioned in the title.
Unfortunatly, they are only physical controllers (so they require that the mac is either software in the mcu or a hardware which can handle them) and at the same time use MII, which isn't implemented in the F28069.
I found plenty other PHY+MAC for ethernet (SPI interface) but they can't handle IEEE1588 hardware, and a software implementation of the standard is too slow for my needs.
Could someone recommend me a solution? I'm using the stick also for 3 ADC, blinking 4 LEDs, and 2 PWM signals based on reference sine.
If I should change the controller could you recommend me one which comes with a small evaluation/development kit like the control stick.
Of I could even work directly with the microcontroller (wouldn't actually like it since that's not the purpose of my project) for as long as I could implement it on a 2 layer PCB.
Thank you very much.
Best regards,
Emanuel
Emanuel,One option is to instead move to the F28M35x device. It's a dual core C2000 device in which the C28x core is open to doing control processes and the M3 core is set up for Ethernet. The M3 has an MII interface and has several examples which show how to use the MII with a Ethernet PHY. The only real kit that could show this off is the TMDSH52C1 Experimenter's Kit: http://www.ti.com/tool/tmdxdockh52c1Depending on your application, the Stellaris series of MCUs may be a better fit. http://www.ti.com/lsds/ti/microcontroller/arm_stellaris/kits_modules.pageThank you,Brett
