hi.
I have a PiFace (shim) RTc clock that I try to use on an old rpi2 (b+)
So I have enabled i2c in /boot/config.txt with
$this->bbcode_second_pass_code('', 'dtparam=i2c=on')
Then, for the moment I do that manually
$this->bbcode_second_pass_code('', 'modprobe i2c-dev
modprobe i2c:mcp7941x')
and finally
$this->bbcode_second_pass_code('', 'echo mcp7941x 0x6f > /sys/class/i2c-dev/i2c-1/device/new_device')
but then I have no rtc device.
Moreover when I run$this->bbcode_second_pass_code('', ' i2cdetect -y 1'), I got no device found on the bus.
So I wonder what do I do wrong ? I followed what is said in this thread viewtopic.php?f=31&t=8243
I wonder if the piface RTC is defective. By carefully looking at it, it seems to lack a soldering at one point. The photo make it non obvious because it appears as if there is a big bulk of soldering whereas there is none.
If I compare that to the official photo of it
Any help ?
Thanks
