Phew, glad to hear

Try Prescale = Fosc/32 ... etc

That does sound odd. I suspect the SPI, could you try running it slower, or perhaps change the sample point to “Middle”?

Could you remove the sending from the Flowcode project, and just do the receive?
Maybe flash a LED or output when the message is received?

I am having trouble absorbing all the information
Are you concluding that a message is being received, but that the data is being read incorrectly?

Yes, what I meant was that the pins PC14 and PC15 are not working properly as inputs because the 446 device uses them for the low speed clock. It looks like this isn't fully disabled by default. I'm still looking into how to fully disable the clock and setup the pins as inputs (i.e. all the register...

I think the issue is due to PC14 and 15 being related to the LSE. I recall that on Nucleo boards some jumpers need changing to switch out the oscillator components. If the input isn’t working on your board either, then it looks like some config is missing, but I’m not sure what yet. None of this rel...

I've just had another look at your program,
you need to do a CheckRx(0)
Because Rx buffer 0 is set to accept all, it will receive the message with ID 5, not buffer 1

1. What should i have for settings in RX buffer 0 to filter out that i only recive ID 5 ? Mask ? Filter ? Where the Mask bit is 1, the Filter bit will be checked to match with the receive ID bit So if Mask is 0x7ff and Filter is 5, then only message ID 5 will be received 2. call component macro Che...

Could you separate out the problems by first just sending a message and see what the CAN analyzer makes of it? For the messages transmitted from the PIC/Arduino, what bus rate does the CAN analyzer indicate? Does it detect any errors? It might help if you replaced the 500mS delays with a fixed count...

Hi Karthick
Are you using your own PCB, or are you using an ST Nucleo board?

See attached
This reads the pin state into the variable sod_di
Hope it helps.
Are you also saying that you need to turn the pull-up on, read, and then turn off again?

Hi Jorgen,

I thought there might be a virtual drive, in Windows File Explorer, like F:DIS_F
If not, try changing the attached file in C:\ProgramData\MatrixTSL\FlowcodeV8\FCD\ARM directory

Hi Jorgen,

When you plug the board into USB does it appear as a virtual drive?
The programmer is looking for the name "DIS_F", maybe it is something else?

Hi Karthick, Attached is the updated version. I have moved the reading of SOA_DI into a macro/function such that only the C code is executed on the target build. This is done with the correct selection of a new property SIMULATION, which needs to be set to NO before you do a build to target. (There ...

Hi, Unfortunately, the pull-up, pull-down feature of the ST ARM IO is not directly implemented within Flowcode. However, it can be done with some C code, but there is a complication. Flowcode access to IO usually also sets up any port/pin direction. For the ST ARM implementation we use the HAL libra...

Select Pi3, it will work the same

Hi, Here is some C code to get us started, It uses Port A pins 0 and 1 for the encoder signals, this is the initialisation ... // Setup Port A0 as TIM2 CH1 input // Alternate function mode GPIOA->MODER |= 2; // Set to AF1 GPIOA->AFR[0] |= 0x0001; // Setup Port A1 as TIM2 CH2 input // Alternate funct...

Hi,
Thanks for confirming.
I've updated these already
So you can run the full update.
Thanks

Hi Sacha, It's difficult to give a general/generic answer to this. It is possible to call the HAL functions from Flowcode, using a C icon within Flowcode macros. We could probably best help by taking one example, can you give an exact example of what you want to do? Please give all information that ...

Have you set the AVR SS pin as an output?

Try setting "Toggle CS" to "Yes"

In theory it should be possible to utilize the ST HAL libraries,
but it won’t be trivial and it’s something I haven’t attempted yet.
Could you consider a UART to USB bridge, FTDI, CP210x etc?

Hi,
No, sorry, we don't yet support the STM32 USB peripheral in Flowcode.

Thanks Martin

Hi Martin,
