Swordfish

I'm using an18f47q43 for some software spi comms and the slew rate looks a bit slow compared to other pics at approx. 200ns, I noticed the datasheet has mention of slew rate control so I tried adding the following after setalldigital SLRCONA = 0 SLRCONB = 0 SLRCONC = 0 SLRCOND = 0 SLRCONE = 0 and al...

odd, sorry for the delay i thpought i had replied,

i get this, from work and my mobile.

I'll try again from home.

anyone know what's happened to the firewing website?,

anything we can help with?

I have a work around now but I don't like it. I have 2 pcb's connected via rs485 if I check ISRRX.DataAvailable too often (1ms) i seem to get modifications to my input string where I collate and check the incoming packet. even though if i send the input byte to a debug output the bytes coming in are...

I'm having some really odd problems with receiving data over usart using the isrrx2 routine using a 47q43 part. I had a look in the library folder for interrupts and noticed there is a xvISRRX2.bas file should i be using this for the q43 series?. PS is there a prefered method of checking how much da...

Thanks Gerry that works really well, although..... I spent much too long trying to diagnose a problem that didn't exist because I didn't realise i had to select the umc button on the mcloader and i doesnt really show that its selected. thanks again for your help on this i really appreciate it. Richard

Thanks Gerry I'll have a look at this tomorrow

Thanks Gerry,

I was expecting the pins to use portc.6-7 but the datasheet was unclear on the tx1 pin it just said it was remappable.

anyway portc.6-7 are fine for me.


Thanks

Any luck with this Gerry?

I really don't want to hassle you as you are generously offering your time, but i have a breadboard on my desk ready to try it before i finish a board design, and i'm unsure what the default pins are likely to be.

Thanks Gerry

Hi I thought i would start a fresh thread on this as it may be useful to others. start with the basics as I have no idea what I'm doing and it may help others. 1. I looked in the swordfish folder for the umcloader app, firstly is this the most up to date app or should I be looking for download? 2. w...

yeah you think the disable input would be ideal and i was using it, but....... there is an obscure Tb321 application note which suggests that you can get shoot-through faults. if you don't start with certain configurations. although i'm starting to think that only applies to the original part. there...

Hi 'm having small issue with A switching IC it's a hip4081a and there is an issue where is can blow itself up on start-up if its pins and brought up incorrectly. long story short... i need to either use the clc's to invert the pwm output onto a different pin and also set both to low on startup or e...

Thanks David

I'll have a try at this when i have a board to try it on and some time.

Thanks Jerry, I'll look at getting some q43 parts and get them working in the current project. I'm feeling bad about not starting this as a new thread. is there a specific website dedicater to umc? do i need to add anything to the swordfsh code to "use"/skip over the bootloader? Thanks again Rich
