App note from NXP demonstrating capacitive pin channels expansion on LPC804 MCU with SWM (switch matrix) and scan sequences. Link here (PDF) The CapTouch module on LPC804 supports only 5 channels by hardware. Normally, the device with up to 5 channels can fulfill some simple use cases. But if more channels are required by the […]

App note: SPI flash programming algorithms for LP546xx
App note from NXP giving step by step guide on creating flash programming file for MDK and also using pre-compiled flash programming algorithm which can be used directly. Link here (PDF) LPC546xx has external spi flash interface(SPIFI) which can R/W external flash with single/dual/quad mode. It also supports XIP mode which means code can be […]
