We have received the attached waveform file from EInk and need to convert it for the firmware. Can you convert it and return, or direct us to a tool that will let us to the conversion?
Second, we would like to enable REGAL waveform support within the MX6SLL processors going in our product.
We are finalizing our first build of software for production and would love to include the best performing waveforms. The folks at E Ink mentioned that we may need the controller firmware from NXP in addition to the actual waveforms but they weren’t sure and suggested we talk to you. Any help would be appreciated!
Hi @max_tsai -
Our WBF file is covered by EInk NDA so I can't attach here but I can email it to you. What address should I use?
Am I understanding correctly that as long as we are using a waveform file with REGAL waveforms in it, then the hardware will automatically enable REGAL?
Please mail to email@example.com.
Yes. It's correct as the waveform including REGAL and assign the waveform mode (GLD or GLR) into driver.
I can convert the Eink WBF to firmware and also timing table. Please attach here.
REGAL is supported by HW waveform engine with 6SLL. EPDC driver support REGAL for 6SLL. When you assign the waveform mode from user space, driver will recognize it as REGAL.
