Re: MAX3100 on SPI...

Hi Folks, Well the serial cable showed up yesterday, and this morning I found some time to do some tests with the MAX3100 driver. Note for various reasons I'm testing with kernel 3.6.11, however, the behaviour is the same, and the MAX3100 driver has not been modified in over a year. Found why the Pi...

Re: MAX3100 on SPI...

It's available as a module. I -think- you need to still hack the kernel ala http://www.bootc.net/archives/2012/05/19/spi-on-the-raspberry-pi-again/comment-page-1/#comment-24218 That said, I just tried this, but the Pi is hanging the moment I load the spi_bcm2708 driver, but I cant debug via serial p...

MAX3100 on SPI...

Hi Folks, My MAX3100 SPI UART chip arrived today along with the breadboard and wiring gubbins. I've wired up MISO to Dout, MOSI to Din, CS [ to ground], Vcc to one of the 3.3V pins, Ground, double checked every connection, but can't seem to get the max3100 driver to create a /dev/ttyMAXn device file...

SC16IS762 via I2C or SPI...

Hi Folks, I finally have a SC16IS762 demo board, that I want to hook up to a Pi. I've seen suggestions that there is indeed a driver for it, but couldn't find it referenced in the kernel source. Anyone know where I could get a patch ? Alternatively, assuming the driver is unavailable and/or not full...

Re: kernel patch for Dallas 1-wire interface

Doh! My bad, I hadn't loaded the w1_therm module. That'll teach me to do these things early in the morning. All works great now, and I'll add the third one tomorrow

Sorry for the noise

Re: kernel patch for Dallas 1-wire interface

Hi Folks, I have three DS18B20's, and have installed 3.2.27+ on my raspbian image, and modprobed the w1-gpio module. I see the /sys/bus/w1 directory populated. cat /sys/bus/w1/devices/w1_bus_master1/w1_master_slaves shows the two I have currently connected, while w1_master_slave_count also shows a c...

Re: FTDI USB Serial Hangs

Ubuntu doesn't run on the Pi as far as I'm aware (at least no recent version). Do you mean Ubuntu on the PC ? or Are you running 9.04 ? If the former, indeed, there is no problem on the PC platform, and in fact I understand there is no issue on other ARM platforms, the issue is Pi (or USB Controller...

Re: mini UART vs PL011 Deathmatch...

Hi Tony, Ah, yes, that explains everything, thanks. Darned annoyance, although I think I might be able to do the NTP PPS stuff GPIO anyway, so I'll look into that [Seems others have already done it] To The HW guys/Foundation, if you ever do a Pi "Master" version, please consider bringing this serial...

Re: FTDI USB Serial Hangs

Can't help suggestion wise, but can add my voice to the chorus I'm afraid. I have a FTDI USB<->RS485 adapter, with an FT232R in it....Usual locking up after trying to access the device. The odd echo blah >/dev/ttyUSB0 works fine, but too many operations and it hangs...

mini UART vs PL011 Deathmatch...

Hi Folks, While googling to try and resolve the famous FTDI USB issues, I discovered that the Pi actually has two serial ports "on-board", not just the 3 pin mini UART that I knew about. I understand that in fact there are two serial ports "on-board". The mini-UART 3 pin 3.3v port, as well as the PL...
