Yes, in my previous post you can see that I've tried also with that values with no luck :( I'm really frustrated :mad:

Not sure if this is what you ask for, but I've checked the programmer options, OSC is setting to HS, there is a option for HS w/PLL on but it's not enabled.

Can you verify the BRG values?

I've got the BRG values using Microchip Can Bit Timing Calculator (from www.intrepidcs.com), it claims to be compatible with MCP2510, I think that the values are same for my MCP2551, also tried with...

Well, I've connected the board to a PC using a CANUSB adapter listening at 100Kbps, but does not receive anything. This is the code (18F258+MCP2510 20Mhz):



define OSC 20

TRISB = %000001000...

Thank for your step-by-step guide! I'll try to begin with the project this weekend.

I've post in PBP pro but nobody seems to know, so let me post here since is a CanBus question:

I've a small proto board (without datasheet) connected to a Can network and I'm trying to make a very...

Hi

I've a small proto board (without datasheet) and I'm trying to make a very simple app but I don't know how to do. It has a 18F258 (20Mhz clock) and MC2551 and I want just send a CAN command,...

I'm not english spoken, but USART is on RB.1 (RX), I can not use that PIN, just RB.6 for incoming data, and RB.6 as far as I know, can not be managed with interrupts.

It's a finished PCB and I'm...

But that way is intended to use the INT port. I'm using a PCB with 16F628A, INT=RB0, and the port I must observe is RB7, so I can not see how to use Darrel's way :confused:

How can I control when data is incoming? I have a pcb with Max232 and it sends/receive data, this is a portion of the code:



'Waits 200ms until 129 is received, then store next byte in I, if...

So Mister_E answer is wrong, I'm always talking about a PIC+MAX233! Without the Max I can comm with the PC (can receive from, but not send to)

Can you explain me what are the difference between...

Something does not works :(

I'm testing with another board, just a 16F628A 20mhz OSC and a MAX233 that sends 'D00000' or 'D11111' every time RB.4 changes, it works ok if I use True Mode T9600...

I can try it, would be enough a 47k resistor?

With OPEN transmission does not works, nothing happens, I think that mode is for direct connection to the PC.

I'v solved the mistery of the broken PICs (just a programmer bug), anyway if someone...

I have a board with two 16F628A and one Max233, and I want to share it with the two PICs.

Apparently it works ok but one of the PICs has been damaged (I can't reflash it), I've tried with another,...
