ok, thank you. I am not the biggest fan of wine but maybe I will give it a try.

Best regards,

Btw, on Linux machines, you may install REX development tools using Wine 2.0 or later. Although we test the development tools in Wine regularly, please note that this is meant for experienced Linux users and only a very limited support is provided.

Best regards,

I will migrate my environment soon. Then I will have access to a Development-station with MS Windows. I still own the PIO Board.

Would it be possible to try your libpio in front to fully setting up REX? Is it in a deb package on your site?

Thank you very much again,

our PIO driver is based on the libpio.so library however we implemented it in our own way - this can be reason why it is possible to use PIO boards on newer RPis such as RPi 2 or RPi 3 with REX Control System. It seems that Intellisys doesn't support PIO board any more (my personal guess according to their outdated website).

Fully supported operating system for REX Development Tools is only Windows at the moment. However it is possible to use it also with WineHQ (should be compatible with Linux and also Mac OSX).

I would recommend you to try REX Control System by following Getting started with REX and Raspberry Pi .

If I can be of assistance, feel free to contact me.

the Pi B+ is working. Thank you again for your config.txt. I compared it and also copied it but unfortunately with no new results. When I look for strings in the libpio.so I only see reference to the chipset bcm2835.

bcm2835_delayMicroseconds
bcm2835_st_read
bcm2835_st_delay
bcm2835_gpio_write_multi
bcm2835_gpio_write_mask
bcm2835_gpio_set_pud
bcm2835_spi_begin
bcm2835_spi_end
bcm2835_spi_setBitOrder
bcm2835_spi_setClockDivider
bcm2835_spi_setDataMode
bcm2835_spi_transfer
bcm2835_spi_transfernb
bcm2835_spi_writenb
bcm2835_spi_transfern
bcm2835_spi_chipSelect
bcm2835_spi_setChipSelectPolarity
bcm2835_i2c_end
bcm2835_i2c_setClockDivider
bcm2835_i2c_read_register_rs

I can't find any reference to the chipset of the Pi 2 bcm2836. I also tried to contact someone at Intellisys. Bad luck. In the past these guys were really helpful and friendly but I think the system is not really supported anymore?

Is Rex completely independent from the libpio.so? Is it possible to write small c / python programs with Rex or do I have to use the GUI on MS Windows? Is there are MAC or Linux port?

Thank you,

demarque

thank you. I tried already to Pi 2 model B. First I also thought that it must be a hardware / failure related issue - but after trying the 2nd one I do not think so any more. I ordered a Pi B+ - at the moment I would bet, that this one works. I will inform you.

Regards,

demarque

the Raspberry Pi I tested is Pi 2 model B.
Here is my config.txt file.

According to your posts it seems to me like some hardware issue on your Raspberry Pi.

If there is anything I can test for you, please, let me know.

Cheers, Tomas

It is weird.

I've checked it again. No luck. Maybe the Pi GPIO's are damaged? Can you provide me with you config.txt? I tried to interface with the PIO directly.

#include "/var/tmp/pio/libpio.h"
#include <unistd.h>

int main (void)
{

        int RTC_status;
        int RTC_year;
        Pio_SYSTEM_Init();
        RTC_status = Pio_RTC_Start();
        RTC_year = Pio_RTC_Year_Read();
        if (RTC_status == 1) { printf ("The clock is started successfully %i\n");}
        if (RTC_status == 0) { printf ("The clock was just started %i\n");}
        if (RTC_status == -1) { printf ("The clock is not started %i\n");}
        printf ("The current year is : %i\n", RTC_year);
}

The output is:

The clock was just started 0
The current year is : -1

The c code works on other Pi's with the same PIO

Thanks again
