Holtek 5V wide voltage Cortex-M0+ touch-enabled MCU-EEWORLD

Collect

Holtek has launched the HT32F542xx series of 5V wide voltage Arm® Cortex®-M0+ Touch microcontrollers, which have a maximum frequency of 60MHz and provide up to 28 touch keys. They can pass the CS (Conductive Susceptibility) 10V dynamic test and also have a built-in LED controller with automatic scanning function.

It is suitable for various electrical products, such as air fryers, rice cookers, smart door locks, washing machine panels, etc.

The HT32F54231/54241 series has a Flash capacity of 32KB/64KB and an SRAM capacity of 4KB/8KB. It provides up to 24 touch keys and supports automatic detection in Deep Sleep Mode 1/Deep Sleep Mode 2, making it suitable for low-power product applications. In addition, it provides a wealth of peripheral resources, such as USART, UART, I²C, SPI, 10-channel 1Msps SAR ADC, etc. Packages include 28SSOP, 32/46QFN, and 48LQFP.

The HT32F54243/54253 series has a Flash capacity of 64KB/128KB, an SRAM capacity of 8KB/16KB, and provides up to 28 touch keys. The peripheral resources cover the HT32F542x1 series, and additionally provide 6-channel PDMA and 2 sets of comparators, suitable for a wider range of applications. Packages include 32/46QFN and 48/64LQFP.

In addition to supporting professional IDE manufacturers such as IAR and Keil, Holtek also provides a learning board (Starter Kit), ICE tool e-Link32 Pro, peripheral driver library (Firmware Library), touch key library, application sample code, etc., with Holtek ISP (In-System Programming) and IAP (In-Application Programming) technical solutions, it can easily upgrade the firmware and help customers shorten the product development schedule.

ARM9 system clock and serial port (non-flow control + non-FIFO + query mode)

The purpose of the experiment is to set the system clock and input a character on the serial port. After receiving it, the board will add 1 to its ASCII value and output it from the serial port.

uC/GUI transplantation example on ARM core S3C44B0X

uC/GUI is a graphical user interface (GUI) software package for embedded systems launched by Micrigm. Since uC/GUI is written entirely in ANSI-C, it is independent of the processor and can be easily ported to different operating systems and embedded microprocessors, and can support graphic LCDs of different sizes.
