Alright, I got my CAN stuff working in ID/mask mode, with 'all accepted' values.I need to setup a CAN filter to only receive STD ID of 1512 (0x5e8).I'm confused why this doesn't work. Using SPL looking at the CAN examples. I saw IDList, and this se...

I'm trying to get my STM8AF5288 to read CAN from a TJA1050.I had it reading perfectly. 1Mbps @ 16Mhz. Using time_seg1 of 8, tim_seg2 of 7, prescale of 1. SJW1.The sending unit is an Arduino attached to an MCP2515 and TJA1050. Verified with anothe...

Trying to think about it in binary....0x5e8 - 010111101000Appending RTR of 0, IDE of 0 to the end.0x17a0 - 01011110100000Now, in IdMask mode, this appears to work:/* CAN filter init */ CAN_FilterNumber = CAN_FilterNumber_0; CAN_FilterActivation =...

Alright, it looks like there is something wrong in my PCB design. Using an external TJA1050, I am able to get CAN to the STM8 again.

I used a logic analyzer to check the signals going into the TJA1050. Everything looks good.I was thinking, I do the CAN_Init(), but never do anything for the interfaces. Do I need to declare RX as input and TX as output? Pull high, pull low, push-...

Checked clock on CLK_CCO, verified a solid 16Mhz.Power looks great throughout the board.Because it was working before, I suspect there is something in the code somewhere.Keeping on it. STM8AF series seems like a great package for small auto applicat...

Here is the code I'm testing with right now, which previously worked. Changed transmitter to go back to 1Mbps, so I'm using the sample code that should be reading 1Mbps. /* MAIN.C file * * Copyright (c) 2002-2005 STMicroelectronics */ #include "...
