[SOLVED] I2C LCD - Setup instructions for 16x2 Oct 23, 2012, 11:37 am Last Edit : Nov 16, 2012, 02:55 am by ianbren Reason : 1 Like many on this discussion group, I bought an I2C LCD device for my Arduino only to find that the documentation is either non-existent or, if it does exist, just wrong. nRF52832(Preview版)が載った、nRF52 Preview-DKというボードを持っている。 PCA10036とも言う。 今週、東京や大阪で行われた説明会では、PCA10040というボードが配布されたようだ。 PCA10. MAXCNT Electrical specification PDM Electrical Specification. Many hardware specific module (I2C, GPIO, ADC etc. As masters are usually micro-controllers, let's consider the case of a data transfer between two microcontrollers connected to the I2C-bus (see figure above). This is a simple short and easy tut. nRF52832 SPI/I2C master example with SSD1306 OLED. When I try send transactions larger than this the transactions fail (even after playing with a larger timeout etc).
