I am using FT810 with FTDI VM810C "credit card module", which uses the FT810. I am trying to get my program to work with either the Riverdi or 4D modules which use FT812. I can't seem to get either to work with the settings in MB Pro / VTFT that I use for the FT810 board. Any thoughts? I am using mi...

I am using FT810 with FTDI VM810C "credit card module", which uses the FT810. I am trying to get my program to work with either the Riverdi or 4D modules which use FT812. I can't seem to get either to work with the settings in MB Pro / VTFT that I use for the FT810 board. Any thoughts?

Yes, I understand the limit. My question is whether there might be a trick to repeatedly refill the buffer and send packets successively within one interrupt event. If so, what would the sequence be? Do I have to repeatedly clear the buffer or just change the contents before sending the next packet?

I have the same problem as Mike. I need to transfer 512-byte packets to efficiently move my data, otherwise it takes 8 interrupts from the host to transfer all the data. Is there maybe a trick to force the larger block of data to be transferred based on one interrupt? Like maybe creating a loop to c...

OK. More data... If I load the v1.3.0 bootloader firmware from the mikromedia+ for PIC32MX7 web page, everything works perfectly. If I compile the USB_HID_Bootloader project from the compiler examples folder, and then load that, I'm back to the problems. Does this project create v 1.3.0 hex code, or...

Hi, Please can you specify which PIC32 is used with bootloader? PIC32MX795F512L Did you check your Project settings? Yes, they appear to be normal. Which settings are critical for the bootloader? Also please check Bootloader Project settings and your circuit? I have now tried it with my Fusion 7 bo...

I am trying to use the bootloader in a product so that users can upload firmware changes, but I am having trouble with the bootloader running properly. Sometimes it doesn't start and I have to power cycle the board once or twice before it is recognized by mikroBootloader. Then after programming, som...

Thanks...

I have msgs after compiling like...

0 1144 Used RX: 32 (100%) Free RX: 0 (0%) Used RX: 32 (100%) Free RX: 0 (0%)

I don't explicitly write anything to this memory. Do the libraries do this? Should I be concerned that it's at
100%? Is there a way to manage this memory or does it matter?

Thanks. I ordered a microProg, but it takes time to arrive. In the meantime, I was able to program the external board using 5 wires from the Fusion MCU socket to the appropriate pins on the external MCU. Hi, We usually do not recommend to our users to use on-board programmer from development boards,...

Can I use the ICD in Fusion to program an external project with a 10-pin programming header? Can I just connect the Vcc, Gnd, MCLR, RB6 and RB7 connections on the ICD connector to the appropriate pins on the external board? I don't need to debug... just program the PIC on the board.

The documents are not publicly posted and are protected by non-disclosure agreement, but I think it's safe to describe the audio output circuit. I will send you a private email. You might also consider emailing them about getting the documents and signing the NDA. Hello lpmsr, I haven't heard someth...

Yes, that's correct. My current crystal is 3.58MHz, but I have some 10MHz crystals which I guess I should use since it gives me more flexibility. Current draw is not an issue for me.

Hello CS. I was planning on using the circuit published by FTDI for their eval board, which has a multistage filter following the audio output of the chip. Is this similar to what you did? How much better are the results? I decided to offload the audio for my application to a VLSI chip like the one ...

Your settings look OK for my purposes, except maybe for Boost and OS. I was planning to use OS=128 and Boost=1. What crystal frequency are you using?

Thanks.
