Content for LPC845


Based on the Arm® Cortex®-M0+ core, LPC84x is a low-cost, 32-bit MCU family operating at frequencies of up to 30 MHz. The LPC84x MCU family supports up to 64 KB of flash memory and 16 KB of SRAM. This family features exceptional power efficiency in the low-current mode using the FRO as the clock source. The peripheral complement of the LPC84x MCU family includes a CRC engine, four I2C-bus interfaces, up to five UARTs, up to two SPI interfaces, capacitive touch interface (enablement coming in Q3), one multi-rate timer, self-wake-up timer, SCTimer/PWM, one general purpose 32-bit counter/timer, a DMA, one 12-bit ADC, two 10-bit DACs, one analog comparator, function-configurable I/O ports through a switch matrix, an input pattern match engine, and up to 54 general-purpose I/O pins. This device is fully supported by NXP’s MCUXpresso Software and Tools, a comprehensive and cohesive set of free software development tools for Kinetis, LPC and i.MX RT microcontrollers. MCUXpresso SDK also includes project files for Keil MDK and IAR EWARM.

DIY ‘Meta Clock’ with 24 Analog Clocks

“The year 2019 is coming to an end, so it is perfect time to finish a project I have working on for the last few weeks: a ‘meta clock’ built with 24 individual analog clocks, controlled by a network of …

DIY Stepper Motor Clock with NXP LPC845-BRK

“This project is about building a stepper motor clock around the NXP LPC845-BRK board. The design is using a combination of 3D printed and laser cut parts and costs below $15. The GitHub repository (see links at the end …
