All,
I've built a data logger for a small electric race car using an Arduino Nano. The data is logged to and SD card and displayed on some OLED displays across a 6 foot wire. I've had TONs of problems where my Arduino would lockup and I'm pretty sure it's due to the I2C bus. After installing some pullups, current limiting resistors and shielded cable, i think i've solved my lock up problem. However there's not enough RAM for larger fonts. Hence I'm moving everything to a Teensy.
I would like to change my display to a 2.4" TFT SPI to get bigger fonts, the display is SPI and i've got a working prototype (all mounted on a breadboard). It works like a dream, but I'm not sure how reliable it will be if i have a 6 foot wire to the display. Anyone have any insight as to if the SPI is more reliable in this configuration?
Thanks in advance.
