Hi I have IMC30A eval board and I want to use the PFC feature to provide  pfc and universal input voltage. But I cannot find any resources to calculate the required inductance for the application. 

Design requirement:

Input voltage: 85 to 240VAC(50-60Hz)

load current max 2.5A(RMS)

Please help!

Hi,

I am working on bringing up a custom board. We have a lot of experience with the IMC101TF048XUMA1 and have integrated this into our design. I am using a iMotion-Link to attach a PC to the board for programming. I am trying to establish the initial communications and to program the initial Firmware onto the IMC101TF048XUMA1.

I can see the UART signals (0-5V) arrive at RX0, pin 45 on this part, but there is no response.

I have also verified on an oscilloscope that the signal is as expected. It arrives at the pin with clean transitions, and I used the same 'scope to verify the UART signal as a series of 4 bytes from MCEDesigner - as you can see on the plot below. Here you can see the incoming signal on the bottom trace. Of course, to look for the response I also zoomed out and looked to the right and found no response from the TX0 pin 46, nor did the MCEDesigner app connected to the port.

One thing I did notice is that the pulses measure at an equivalent of 113.2kBaud rather than 115.2kBaud. This is what the iMotion-Link generates. Is this enough to cause the signal to be rejected by the IMC101?

Any thoughts on any reason why the  device might not respond to this signal?

Here's a schematic snippet for reference. We are using 5V for power, and power is applied to the board.

I am currently using EVAL-M3-302F  with EVAL-M3-CM615PN for an application. I can properly control the motor using the MCE designer.  But to be able to control the motor externally I want it to be done using the UART1 of the chip. I have read in another post on community that UART 1 can also be used for user application without going through the MCU core(A core).

I have followed all the necessary  steps to configure UART1 for user application. I use the example script provided for both(buffer and fifio mode). But It failed to communicated with my external microcontroller. When I probe pin 64 & 63 of the IMC302A-64, the pins are at zero volt. Does this mean that UART1 is not active? 

How can I do this properly ? 

MCE Designer becomes unresponsive and no longer able to turn off the Motor every time I tired to run PFC first and then run Motor.
But there is no problem if I turn on only one(either pfc or Motor) and run.

The  tools that I use for this application are: EVAL-M3-302F for controller and  EVAL-M3-CM615PN for power board. I have the latest version of MCE designer installed which is v2.3.1 and the MCE wizard that I have is v2.3.1. The firmware package that I use for board is IMC302A-F064 MCE Software Package v1.3.3
