USB source code

Hi,

We are looking for any examples of assemble code to implement a USB UART function in a MC9S08JM8CLC part. We do not know C, only assembly. We simply want to send commands from a host PC through an API we are having written to upload and download data from the JM device's RAM and Flash memory. I realize that most USB stacks I have seen are in C but was hoping someone my know of some code availble in assembly.

Thanks in advance for any help.

Paul

Like you, I work in assembler so I have converted the CMX HID

example C code for the JM60 into Codewarrior assembler source.

The HID has the advantage of not need a PC driver, although

data transfer is limited to ~ 10K/sec.

If this is of any use to you, email me.
