Re: I2C failure rate

I've succeeded in using the MCP9600 thermocouple reader chip with Raspberry Pi. Thought I would post my solution here since this thread is the only result when searching the forum for MCP9600. Slowing the bus down by a factor of ten (i2c_arm_baudrate=10000) I still got communication errors. So I use...

Re: Raspberry Pi3 I2C baud rate setting

I can change the I2C clock speed on my Pi 3B+ by editing the /boot/config.txt file and adding to the line dtparam=i2c_arm=on to make it dtparam=i2c_arm=on,i2c_arm_baudrate=10000 Before making the change I measured the I2C clock pulses at about 8 microseconds long using an oscilloscope. After making ...

For me I can use 2 of those 3 things, but if I connect bluetooth mouse & bluetooth keyboard with WiFi enable...

Re: Raspi 3 model B Bluetooth observations

hi ds18s20! I have the same problem, but I've discovered that if you turn WiFi off then the keyboard works just fine. Also see this topic: https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=181410 I'm using Logitech K380 keyboard with Logitech M535 mouse. Both are actually bluetooth and I'm usi...
